TELESCOPIC jib, enclosed geart% box and a minimum jacking height of 4 ins., are some of the features of the M.E. Universal jack-crane made by Mann Egerton and Co., Ltd., Cromer Road Works; Norwich. The length of the jib can be varied from 3 ft. 4 ins. to 4 ft. 10 ins. in 6-in, stages, the respective load capacities of the jib being 30 cwt., 20 cwt., 15 cwt. and 10 cwt. A steel pin secures the jib at the position selected.
The enclosed worm gear has a ratio of 40 to 1, and as friction has been reduced to a minimum at all points, little manual effort is called for, For additional safety, a ratchet device is fitted to the winding-handle boss.
When used as a jack the jib can be loWered to within 4 ins, of the ground. When employed in this way, the lifting hook is replaced by a suitable attachment.
As a crane, a most useful application is that of removing an engine from a chassis. This is where the telescopic jib fully justifies itself.
Mann Egerton and Co., Ltd., is also responsible for a breakdown body, the design of which has been standardized
for direct fitting to certain Austin. Bedford, Corinne'', Fordson, Dodge and Morris Commercial chassis. These bodies, which are of all-metal construction, have a wide range of fittings.
