Infrastructure projects such as freeways and railways often involve bridges with girders and typically conveyor systems have their long trusses.
Transporting those girders and trusses to the job site can be somewhat slow and tedious if transporting the conventional way with a prime mover and trailing jinker.
The trailing jinker is relatively ‘inefficient’ when compared with a prime mover pushing and manoeuvring from the rear.
Customer requirement of BOOM’s low profile prime movers often occurs in two different ways:
Example 1- Long heavy bridge girders and trusses
You can use a low profile prime mover at the front to pull and steer along the desired track and a low profile prime mover at the rear to both push and steer the rear end of the load around corners.
The rear prime mover can prevent the rear end dragging across / cutting the corner. In short, the corners can be turned more tightly. This is can be a big help when moving a long load around roadway corners.
Example 2 – Long heavy girder
You can use a low profile prime mover to assist with the manoeuvring of a long girder on a job site.
A case in point ... the final positioning of a bridge girder, for the final lift onto headstocks. One end moved by a low profile prime mover travelling forward and two cranes slewing the other end into position for the final lift.
