Care should be taken during the set-up procedure to ensure that each adjustment is accurately set, extra time spend here will be saved tenfold...

USPT DAWSON CONSTRUCTION PLANT INITIAL ASSEMBLY ON THE UNIT The new sheet pile threader is delivered packed inside a sturdy aluminium case. Before use the cross slide and vice assembly need to be fastened together, this is a simple case of sliding one into the other, but care must be taken to ensure that this is done the right way round. On the vice assembly a zero has been stamped on the lower edge, this should line up with the graduations on the cross slide support.

USPT DAWSON CONSTRUCTION PLANT SETTING THE ROLLERS TO FIT THE PILE SECTION Before the Universal Threader can be used it must first be accurately set-up for the type of pile that it’s to be used on. In order to do this it’s recommended that two lengths of pile are cut 1 approx.1000mm long and the other aprox.200mm, these must be straight, clean and free from any damage. Stage 1 is to set the rollers, 1 Release the swinging arm clamp bolt. (Picture 3) 2 Slacken the two roller units on the swinging arm. (Picture 4) 3 Screw the 2 pile thickness compensating screws fully in, these are found on the...

(the cocking lever should be pointing upwards) (picture 20 , page 13) 2 Slacken the 6 clamp bolts. (Picture 8) 3 Slacken the bolts on the steady and the guide plates, the bolts for these parts have three positions to enable maximum adjustment, you may have to change the bolt positions later. 4 Engage the threading head...

(Picture 12) 10 Set both steadies so that they are in light contact with the pile. (Picture...

USPT DAWSON CONSTRUCTION PLANT METHOD OF OPERATION When the setting procedure has been carried out satisfactorily do a final check that all bolts that were loosened during the setting procedure are tight. With this check done you can begin to thread piles by the following method. 1 Place the roller unit onto the driven or part driven pile with the swinging arm towards the pan of the pile, (if you are working on temporary works then you will need a bridging platform to stop the roller unit falling through,) tighten the roller clamp screw. 2 Place the threading head into the roller unit will the...

USPT DAWSON CONSTRUCTION PLANT SAFETY Because of the nature of sheet pilling it is possible to damage the sheet pile threader if not used as intended. A crane and a sheet pile can exert tremendous loads on the pile threader if any change to the pile verticality occurs once the pile is secured in the vice unit. Before hoisting the pile make sure that there are no obstructions to the rollers, check for damage, welded on brackets, bent sections, damaged clutches etc. these faults are common on previously used piles and can cause severe damage to the threader as the pile is hoisted. When positioning...
