Delmag Lead Systems

Various applications in the foundation business require economical machines. Therefore Delmag offers a variety of compact solutions like lead systems fitting any model of hammer. They are light, but nevertheless very stable. Exchangeable guide parts enable easy adaption to swinging, rope suspended, hanging, swivelling and other leader types.

Delmag swinging leads can be attached to any model of crane with the proper capacity. Since the lead is not connected to the crane's upper carriage, it can be rotated 360° around its vertical axis. When using an adapter with rope pulleys to reeve in the crane rope, batter piles with an inclination up to 1:1 (45°) can be driven.

Delmag fixed leads can easily be attached to the boom point of crawler cranes. Usually a spotter, which connects the lower part of the lead with the upper carriage of the crane, is used to control the mast inclinations to the front, rear or side. Optionally a hydraulic mast slewing device which slews the mast ± 90° around the longitudinal axis and a hydraulic mast lowering system which lowers the mast up to 8 m below the ground are available. These features make it possible to work under restrained jobsite conditions and to drive piles to any required angle. Different adaption systems also give the possibility to operate other tools like drill heads or vibratory hammers.

Delmag rope suspended leads guide the hammer in "riding hammer" applications, either for driving sheet piles, H-beams or pipe piles on land-based or off-shore projects. Various models are available for pile sizes up to 4.200 mm of diameter.
