Ringlock Scaffolding

Ringlock verticals are the post legs of ringlock scaffolding, including 48 mm diameter ringlock verticals and 60 mm diameter high-load ringlock verticals. The verticals are made from steel or aluminium scaffold tubes with scaffold rosettes welded on at 500mm intervals, which are used to secure other ringlock scaffolding parts of horizontals, braces, and brackets in position from multiple directions, making the ringlock scaffolding the most flexible and versatile metal system scaffold for all types and shapes of construction and shoring. Ringlock scaffolding verticals are available in sizes from 0.5m to 4m, with fixed (unremovable) or bolted(removable) spigots. They are hot-dip galvanised for weather resistance.

Ringlock ledgers are horizontals of the ringlock scaffolding parts, made of O.D. 48.3 mm diameter round scaffold tubes with cast steel ledger heads used to connect to the (rosette) rings on the ringlock vertical legs and are secured by wedge pins with a rivet (called a wedge-head mechanism). Typical Ringlock scaffolding ledgers are O-ledgers (made of round tube), also called ringlock horizontals.  Ringlock horizontals are the basic ring scaffolding parts used to form temporary ringlock support frames and ringlock scaffold towers for construction and to receive O-hook scaffold planks, forming work platforms for access, birdcage, and stage scaffolding.

Ringlock U ledgers are another type of ringlock scaffolding horizontals, made of steel ribbed U profiles rather than O.D. 48.3 mm round scaffold tubes, with two ledger heads and wedge pins at both ends. They are also called U horizontals.  The U ledgers are European ringlock scaffolding parts designed to receive steel planks from both sides, avoiding plank-hook conflicts during erection.

Ringlock bay braces are the vertical diagonal members of ringlock scaffolding, also called diagonal braces, used to secure the ringlock vertical parts to the ringlock horizontal parts at a 45° angle, making ringlock frames and ringlock scaffold towers stable and safe during construction. Ringlock diagonal braces are made of O.D. 48.3 mm scaffold tubes with the ringlock system accessories of brace heads and wedge pins at each end used to fix the braces to ringlock rings.

The base collar is a starter component of the ringlock scaffolding system. They are placed at the bottom of the ringlock standards, providing an initial foundation near the ground, making the ring system scaffold more stable, safe, and sturdy under load. A 240mm long base collar is a component for normal ringlock construction, while 430mm base collars are used for ringlock stage scaffolds for events and staging, etc. Customised sizes are available.

Ringlock horizontal braces are plan braces of the ringlock system scaffold used to prevent the modular scaffold system from twisting and swaying during construction, adding strength and stiffness, thus making the scaffold system more stable and safe. Ringlock horizontal brace is also called a ringlock plan brace.

One board bracket is a console bracket for the ring lock scaffold system, used to support a single plank and form one-board-wide work platforms in the ring lock system side bracket construction.

Ringlock scaffold U brackets are also ring system side brackets. Compared to normal console brackets, ringlock U brackets are made of ribbed U-shaped steel profiles, making them convenient for receiving hook-on scaffold planks from both sides during construction and preventing plank hook conflicts. Ringlock U brackets come in one-, two-, and three-board options, depending on the bracket’s width.

Ringlock two-board brackets are used to support two boards and form a 2-board-wide work platform for the ring system scaffold. In the European ringlock scaffolding system, a two-board bracket, also called a 0.73m scaffold bracket, supports two 0.32m steel planks in the side bracket construction. The scaffold brackets bring the scaffolding platform closer to the building in ring-system construction, making the scaffold system more convenient for workers.

Ringlock scaffolding three-board brackets are console brackets of the ring system scaffold used to form three-board-wide work platforms in construction for workers. Three-board backets are the widest scaffold side brackets in the ringlock system, including O-types and U-types. In the European ringlock scaffolding, the three-board bracket is also called 1.09m scaffold brackets.

An access swing gate is a self-closing door installed at the entrances to scaffold ladders or stairs, providing fall protection during scaffold access. The scaffold swing gates are also called ladder access gates. In the ring system scaffold, there are two types of access swing gates: fixed-length and adjustable (extendable) access ladder gates. They are made of steel and are normally powder-coated in red, yellow, or orange. Galvanised swing access doors are also available.

Heavy-duty steel ladders are a type of straight steel ladder made of O.D. 48.3 mm round scaffold tubes with ribbed anti-slip step rungs and several strengthening plates. They are European ring lock system components in sizes 2m to 4m, equipped with two coupling spigots. In ring scaffolding construction, heavy-duty round steel ladders are secured with scaffold clamps to ring lock ledgers, providing safe access to high scaffolding. Ringlock steel ladders are made of steel material and hot-dip galvanised for weather resistance and long life.

Ringlock lattice girders are a type of scaffold bridge beam, typically equipped with four sets of wedge heads at each end, which connect to ringlock standards during construction. The scaffolding ringlock girders are 500 mm deep and up to 8 m long, made of O.D. 48.3 mm high-strength steel scaffold tubes and hot-dip galvanised. Ringlock lattice girder beams are designed for heavy loads and can support many scaffolding planks and form scaffold work platforms and walk boards, while also allowing a large span opening under the platform to avoid obstacles or vehicle access during construction.

Ringlock toe boards are available in steel and timber and feature an interlocking mechanism. The interlocking scaffold toe boards are secured by the wedge-head system of the ringlock system horizontals and set around the scaffold planks, providing greater safety for walk boards and work platforms for the ringlock stages, ringlock scaffold towers, and ringlock frames. Ringlock interlocking toe boards; no need for extra clamps for assembly.

320mm ringlock scaffolding planks are platform components of the European ringlock scaffolding system, called scaffold steel decks as well. They are made of steel profiles with hooks and wind-protection locks on each side, in widths of 320mm (32cm) and lengths of 0.39m, 0.73m, 1.09m, 1.4m, 1.57m, 2.07m, 2.57m, and 3.07m. The ringlock steel planks are available in two types: O-hook and U-hook. O hook ringlock planks work with the ringlock O ledger, while U hook ringlock planks work with the ringlock U ledger. They are hot-dip galvanised or pre-galvanised for anti-rust purposes.

Ringlock intermediate transoms are components designed to provide an open area on the work platform between two ringlock ledgers in ring system construction.  They have two hooks at each end connecting to the main tubes of the ringlock ledgers and secured by the wedge pins on the hooks. Deep-type ringlock intermediate transoms are placed under the scaffold boards to support them and increase the work platform’s load capacity, enhancing construction safety.

Ringlock truss ledgers are double horizontals in the ringlock scaffolding system, which can take more load and have two sets of wedge head locking mechanisms on both sides connecting to the ringlock system scaffold verticals in construction. The scaffold truss ledgers include two types: the O type and the U type. O-type truss ledgers are made of O.D. 48.3mm round steel scaffold tubes, which are designed to receive scaffold steel planks with O hooks.

Ringlock scaffolding U-type truss ledgers are another type of truss ledger in the ring system scaffold, but are made of steel ribbed U profiles rather than O.D. 48.3 mm scaffold tube, and are called bridge ledgers or double ledgers. Ringlock U truss ledgers are components of the European ringlock scaffolding, used to receive steel planks with U hooks from both sides and prevent plank hook conflicts during construction.  U truss ledger sizes are 1.09m to 3.07m.

The ringlock jack base is a levelling spindle component of the ringlock scaffolding system, consisting of a threaded screw stem, a jack nut handle, and a bottom plate. The scaffold jack base is height-adjustable and is used to keep the ringlock scaffolding level and to make the scaffold ringlock scaffold tower stable and rigid on uneven ground. The adj base jack screw stems can be threaded in ACME 4 TPI (4 threads per inch) or be coarse (quick) threaded in 8mm. Both E-galvanised (zinc-plated) and hot-dip galvanised are available for anti-rust.

Ringlock ledger-to-deck transoms are components of the European  ringlock scaffold system, used to connect to the ringlock scaffolding decks at one end and to the ringlock ledgers at the other end.  The components are designed to create an opening in the work platform during ring system construction, thus allowing access or versatility for constructions with special shapes/obstacles.  There are O-type (made of scaffold tube) and U-type (made of ribbed U profile) ledger-to-deck transoms (ledgers) in the European ring system.

Ringlock scaffolding deck-to-deck ledger is also called a deck-to-deck transom; it serves the same function as ledger-to-deck transoms, which create an open area for access and accommodate special shapes and obstacles on the work platform. The deck-to-deck ledger (transom) connects to the scaffold decks at both ends in ring-system scaffolding construction.  There are U type and O types according to the material used for manufacturing and sizes are one board, two board and three board to create 1-3 board wide open area.

Pin lock scaffold truss ledgers are a type of ringlock double ledgers, but designed with the same diameter for the top and bottom support tubes. They are double horizontal parts of the USA and Canada ringlock scaffolding system, also known as pin lock scaffolding. The pin lock scaffold sizes are 5′ to 10′, used to receive pin lock system steel planks and ensure the high load and safety of the ring lock scaffolding frames and ringlock scaffold towers.

Typical ringlock scaffolding is called a lightweight ringlock system, which is made of O.D. 48.3 mm scaffold tube, while the heavy-duty ring shore system scaffold is made of O.D. 60 mm larger-diameter scaffold tubes and S355 higher-grade steel, and is designed to provide heavy load support for high load concrete slab and beam shoring in infrastructural constructions like highway and bridge construction.

The all-round ringlock scaffolding system is a European ring system scaffold, originally designed by Layher Germany, featuring more scaffold system components and greater versatility for construction, staging, events, and shoring. The ringlock scaffolding conforms to EN12810 standards and has standard sizes of 0.39 m, 0.73m, 1.09m, 1.4m, 1.57m, 2.07m, 2.57m, and 3.07m in ringlock ledgers and horizontals. Wellmade is the OEM ringlock scaffold factory that manufactures compatible components 100% with the original Layher allround system.

Pin lock scaffold system is a type of ring lock scaffolding that conforms to CSA (Canadian STD) and ASTM(American STD) standards. The pin-lock scaffolding is made of S355 high-strength steel-grade scaffold tubes with annealed ringlock accessories to withstand the freezing weather in North America. Unlike the European ringlock scaffolding system, the pin lock ring scaffold ledgers are available in sizes from 2′ to 10′.

The multidirectional scaffolding system is a type of ringlock scaffold designed for Latin American countries such as Brazil and Chile etc. The ring system scaffold has special scaffold rings and ledger blades. Some Latin American countries also choose the European ringlock scaffolding.

Rosette clamps are scaffold fittings for ringlock scaffolding, designed to make the ring connection at any point in the ringlock scaffold system for increased load capacity or to connect around construction obstacles/shapes. Rosette clamps consist of two half rosettes fixed together by rivets and secured to the ring system scaffold by the bolts and nuts.  There are forged-type and cast-steel-type rosette clamps in the ring system. Hot-dip galvanising makes them more durable for repeated use.

Scaffold rings are ringlock accessories welded to the ringlock verticals, forming the modular system scaffold standards/legs. Scaffold rings are also called scaffold rosettes. There are scaffold rings for 48.3mm ringlock verticals and big diameter scaffold rings for 60mm shore system ringlock verticals. Scaffold rings can be made from S235 or S355 grade steel and can be annealed treated for frozen-weather resistance. The normal thickness of the scaffold rings is 10 mm, and OEM manufacturing is available.

The twin wedge head coupler is a cast steel ringlock scaffold fitting featuring two wedge pins and rivets at each size, designed to connect adjacent ringlock standards and secure them together in construction, reinforcing the ringlock scaffold tower and frames for greater load capacity and safety, and making the ring-system scaffold more versatile.  The twin wedge head coupler is also called a ledger-to-ledger coupler.  They are galvanised for weather resistance.

Span lock pins are scaffolding lock pins used to secure two ringlock scaffolding standards vertically by inserting the ringlock spigot between them, ensuring the ringlock scaffold tower remains stable. Span lock pins are widely used in mobile ringlock scaffold systems or when a ringlock scaffold tower needs to be lifted during construction and shoring.  The ringlock span lock pin can be round or square and is designed with two wires; thus, they are also called a square- or round-wire pin.

An Alu-ply platform with a trapdoor is an access platform part of the ring lock scaffold system, consisting of plywood decks and aluminium frames, with a scaffold ladder attached to the trapdoor for climbing up and down in high scaffolding ringlock construction. Alu-ply platform with trapdoor is also called hatch deck in the ring system scaffold; they are 600-640 mm wide and 1.07m to 3.07m in length. The scaffold ladders can be fixed on the platform or separated.

2.15m ladders with hooks are the separate access scaffold ladder of the trapdoor platform scaffolding ringlock. The hooks of the scaffold ladder connect to the hatch deck, forming the ringlock scaffold access system during construction. 2.15m scaffold hook-on ladders can be produced in steel or aluminium. Steel ladders are hot-dip galvanised for a long lifespan and rust resistance, while aluminium ladders are lightweight and easy to handle in ring-system scaffold construction. They are widely used in ringlock birdcage scaffolds and access scaffold towers.

Full aluminium scaffold hatches are also ringlock system scaffold access platforms with trapdoors and ladders, but made of aluminium decks and frames rather than plywood decks like the alu-ply platforms.  The full aluminium scaffold hatches are more expensive than the alu-ply trapdoor platform and are available in sizes of 600-640 mm wide and 1.09-3.07 m in length.

Ringlock scaffolding aluminium stairs are access components of the European ringlock scaffolding system, forming scaffold accessways for workers climbing up and down the high scaffold. The aluminium stairs are lightweight, easy to handle and assemble, and designed with hooks which can be secured with the ringlock ledgers in the ring system construction. Internal and external stair handrails serve as safety handles for workers accessing the scaffold, enhancing the safety of the ringlock staircase scaffold.

Aluminium stair base conf is a staircase component in the European ringlock scaffolding system. They are small, with only 2-3 steps. The small aluminium stair base is designed to provide initial access from the ground/floor to the ringlock scaffold system during construction, enabling comfortable access to the scaffold ring system.

Scaffolding steel stairs are access staircases for the ringlock scaffold system as well, which is made of steel sections. Steel ringlock stairs have greater self-weight. Compared to ringlock aluminium stairs, steel stairs are much cheaper and can support sufficient weight, and are therefore popular access components for immobile ringlock scaffold towers.

Reinforced horizontals are components of the European ringlock scaffolding system; they are designed to have reinforcing elements beneath standard single ringlock horizontals, but the reinforcing elements are lighter designed, compared to ringlock double ledger (truss ledgers). Thus, reinforced ledgers are also called LW (lightweight) reinforced horizontals, which can carry greater loads than the ringlock normal ledgers but are easier to handle during construction. The EU ringlock LW reinforced horizontals can be U-type and O-type for scaffold plank receiving and platform forming. Both U-type and O-type reinforcing ledgers are available in sizes of 0.73m to 2.07m.

A lift-off preventer is a European ringlock scaffolding system component that joins the ringlock U horizontals (U ledger, U reinforced ledger, U truss ledger, etc.) and is secured with hooks. It is used to prevent the scaffold decks on the horizontals from moving and lifting, and is called a deck stop. The ringlock deck stops are also safety ringlock scaffold parts for wind resistance, enhancing the safety of the ringlock scaffold frames and towers. They are 0.39m to 3.07m in length, matching the ring system U ledger sizes.

190mm scaffold decks are 190mm wide and 70.6mm thick (height), made of high-strength steel profiles, which are the platform components of the European ringlock scaffolding. Same as 320mm steel planks, 190mm scaffold steel decks are designed with O- or U-plank hooks that work with the ringlock O ledger or U ledger. 190mm planks fill narrow gaps on the ringlock work platforms, which have lower self-weight and are easy to handle. They are galvanised for weather resistance and long-life repeat use.

Ringlock wedge pins are ringlock accessories of ringlock horizontals, braces, and brackets, used to fix these ringlock scaffolding parts to the rings on verticals and secured by a rivet. Ringlock wedge pins are made from high-strength steel plates and S235 or S355 steel grade. When ringlock scaffold material is produced and exported to countries with cold/frozen climates, the wedge pins need to be annealed to withstand adverse conditions and remain stable and safe. Forged wedge pins are also available.

Ringlock brace heads are ringlock scaffolding accessories for ringlock facade (diagonal) braces, cast steel or cast iron, with a slot receiving the ringlock wedge pin during assembly, connecting to the rosette rings on ringlock verticals and secured by a wedge pin with a rivet in construction, thus forming a diagonal security and enhancing the stability and safety of the ringlock scaffold towers or frames in temporary scaffold staging and shoring support.
