Maximum Crane Specifications - Size and Weight

Maximum Crane specifications – Size and Weight

The brief we have been given states that the crane must:

·         Be able to be disassembled and carried manually over 100m of rough ground.

·         Be able to be carried by a standard Land Rover size 4x4.

From research, it has been found that the average man can be expected to carry 25kg at knuckle height, meaning that any single piece of the crane should not weigh more than 100kg to allow it to be carried by four men.

Research into the capacity of a Landrover Defender 130, as recommended by Landrover for this sort of application, shows that the maximum load capacity is 1243kg, which when accounting for occupants (based on being 4 x 80kg workers) means that the maximum weight for the crane is 923kg.

The overall length of the vehicle is 5130mm which would be the maximum length for any part to be carried on the roof, assuming that the vehicle will be fitted with a full length roof rack. The dimensions of the load space of the vehicle are 1640 x 1060 x 1160mm, so will be the maximum size for any item to be carried in the load bed of the vehicle.
