Design Challenge - March 2010

modular mover - Visionengineering

The major problem of this challenge was to move as much material as possible, in the minimum amount of space. The idea is based on the dimensions of a typical crane component convoy: up to 20m long, 3.5m wide and up to 4m high. From these dimensions, we wanted to create a vehicle with minimum volume that can be deployed to deliver optimal capacity once erected.

For this, we have integrated a fuel cell engine with track motors, to provide the most versatile and clean propulsion possible. To this we add an adjustable frame that alters the vehicle height and position of the ropes to optimise the machine’s movement and stability, as well as deliver the usual ability to swivel 360°.

In addition, a tilting cab concept was employed. Ensuring compactness during transport, it is fully glazed to provide a wide angle of vision once the machine is operational.

The concept behind the boom and other lifting components is to use a structure composed of a large number of triangular modules, which assemble in the shape of a parallelogram. The basic parts are integrated into the vehicle during transport, while any extra modules required for length extensions are transported by another truck, along with the additional counterweights.

Thanks to this modular design, with the number of triangles and counterweights adaptable to the job requirements, we can obtain a large-capacity crawler crane that moves at the speed of an exceptional convoy, with a maximum of just two vehicles.
