Adjustable Forkhead Scaffolding Jacks Guide

Adjustable Forkhead Jacks VS Fixed Forkhead Scaffolding

Scaffold forkhead jacks are with adjustable spindles. It can be positioned at different heights by running the jack nuts. Sometimes, it can also help with scaffold leveling.
Scaffold fixed fork heads do not have adjustable screw stems. Instead of the adjustable screw jacks, the fixed forkhead scaffold spigot joints are used to connect with the scaffolding verticals. Fixed forkhead scaffold connectors are made of scaffold tubular and steel stripes. They are versatile to be inserted into no matter the small or big hollows of the scaffold verticals.
Both adjustable and fixed fork head scaffolds could be used in concrete shoring systems. But when you use the scaffold post shore props, you need a fixed fork head. The reason is the top plate of the adjustable scaffold props are always with small holes. Only fixed fork heads are able to be inserted.

Adjustable Scaffold Forkhead Jack Dimensions

Wellmade designs the adjustable forkhead jack dimensions according to your scaffold types.
For example, if you use an OD48.3mm scaffolding system, like the normal duty ringlock, cuplock, kwikstage, quick lock scaffoldings. We will manufacture OD38mm adjustable forkhead jacks to match the scaffold’s vertical inner diameters.
If your scaffolding systems are heavy-duty shoring scaffolds, like Crab 60 scaffolding, Shoring Frames, and Shore System Ringlock, then OD48mm adjustable forkhead jacks are required. Because these scaffolding standards are made of OD57-60mm scaffold tubes. Thus OD48mm adjustable scaffold forkhead is matched well with them.

Hollow Type VS Solid Type Adjustable Fork Head Jacks

Hollow-type adjustable scaffold forkheads are made of tubular scaffolding. According to the scaffold tube types, you can find seamless tube and welded tube adjustable fork head jacks.
Hollow-type adjustable scaffold fork heads are the most common type of forkhead jacks. It is light in weight than solid jacks but can take heavyweight in the slabs and beams construction.
Solid forkhead jacks are not as popular as hollow types. They are made of solid steel round bars. The diameter of the solid forkhead jack stems can be 30mm to 48mm

Adjustable Forkhead Jack Finishing

For anti-rusty purposes, adjustable scaffolding forkhead jacks are always finished in painted or galvanizing.
Painted fork head jacks are cheaper than galvanized ones. But the anti-corrosion function is not as good as galvanized ones.
There are two types of galvanized forkhead scaffold jacks: hot dip galvanized and cold galvanized.
Hot dip galvanized forkhead jacks are the most durable. They can last more than 20 years without being rusty. Cold galvanizing is not as good as hot dip galvanized scaffold forkhead jacks, but the cost and prices are much less than hot dip galvanizing.
