CRANES SELF-MOBILE No. 1
For general handling of heavy or bulky stores at depots or in the field.
The crane is a hydraulically-operated slewing type mounted on a 7 ton chassis/cab. The jib is of the cantilever type with two articulated sections each of which can be raised or lowered hydraulically independently. The arc of slewing is 220° and all movements of the crane are controlled from the driving seat of the vehicle.
Three hooks are provided, one 2 ton hook in fixed position, one 26 cwt hook capable of being propelled along the front jib for a distance of 5 feet and one fixed hook on end of jib for lifting a load of 11 cwt. No ropes are employed as the hooks are fixed to the jibs. A locking pin is provided to lock the superstructure with the jibs forward over the vehicle cab when travelling on the road.
A toolbox of generous proportions is provided to accommodate sling chains, lifting beam and pole timber grab.
