Ringlock Scaffold Base Collar

The base collar is a part of the ringlock scaffolding system. It is with a rosette ring, an inner tube, and a socket outer tube. During the construction, the base collar is used to form an initial ground level of horizontals for ringlock scaffolding system.   The ground horizontals are very close to the ground. This makes the ringlock scaffolding tower safer and more stable than other system scaffolds. So base collar is definitely the start element of the ringlock scaffolding system. That is why we call base collars starters too in the ring system scaffolding.

Base Collar Guide for Ringlock Scaffolding

The base collar is a specific ringlock scaffolding system part. Any other scaffolding systems(cuplock, kwikstage, quick lock, etc) do not have this special component.

What is ringlock?

Ringlock is one of the modular scaffold systems used popularly in global wide for the temporary and permanent support of construction.  It is with rings on verticals and ledger heads and wedge pins on horizontal parts.

Ringlock scaffolding is construction scaffolding formed by ringlock system components and parts.  The scaffolding is different from the tube and clamp system. There are all prefabricated and connected automatically. No need for assembly by the huge quantity of scaffold couplers and fittings.

Why use the base collar in ringlock scaffolding system?

Compare to ringlock standards, the base collar is very short in height and has one rosette. Same as the rosette rings on ringlock standard, base collar rosettes are used to connect with ringlock horizontals too during scaffolding tower and frame erection.

But base collar rings are at a very low position.  The low position makes the ringlock scaffolding horizontal lines near the ground.  The bottom horizontal lines make the whole scaffolding tower more stable. It also increases construction safety and scaffold tower load capacity. That is why ringlock scaffolding is commonly used in high construction scaffolding.

How to use ringlock scaffolding base collar in construction?

As one of the ringlock system components, the base collar is modular scaffolding accessories. The socket tube of the base collar is with bigger diameters. It is used to connect with ringlock standards. In construction, you just need to insert the ringlock standard inside of the base collar socket tubes.

Adjustable scaffolding jack bases are inserted into the inner tube of the base collars. Thus it joins together with all of the three components of ringlock scaffolding system: base collar, base jacks, and first ringlock standards.

Base collar rings are used to connect with ringlock ledger heads. While the wedge pin on the ringlock ledger locks and fixes them together.

For normal construction, short(normal) ringlock scaffolding base collars are required. But if you want to set staging scaffolding, you need to use the long-size base collars. That makes your required staging height possible.
