/MPROVEMENTS in ease of control and manceuvrability have received particular emphasis in the recent design of mechanical-handling appliances. Torque-converter transmission and powered steering. and braking have become standard features of many of the machines on show at the Mechanical Handling Exhibition at Earls Court, London, which opened on Wednesday and closes on May 17.
Latest types of mobile crane accentuate means for quicker operation without sacrifice of the ability to work in confined spaces. A number of fork trucks is now offered with engines running on liquefied petroleum gas, whilst the range of front attachments for such models includes devices which allow certain loads to be handled without pallets. Other developments in this field include mechanisms which remove loads from the forks, thus obviating the need for the truck to reverse in a straight line once it has deposited its pallet.
A variant of the fork truck—the reach truck—is now firmly established, having proved its worth as a space saver, being able to deal with loads that would
otherwise require larger conventional appliances. British manufacturers of mobile shovels and bulk loaders have developed machines which rival in size: and power designs which were previously available only from abroad.
The Exhibition is open daily from 10 am.6 p.m., and is organized by Mechanical Handling.
STATED to be operable in congested areas in which a lorrymounted crane could not be employed, the Rapier 4 fast standard mobile crane is introduced by Ransornes and Rapier, Ltd., Waterside Works, Ipswich (Stand 56). The machine has good manoeuvrability, although the driving controls are light to operate. It can lift 8,000 lb. at 4-ft. outreach up to 14 ft., or 3,600 lb. at 10-ft. 4-in, outreach up to 6 ft.
Incorporating a Ford 6D engine for mobility and a 4D engine for crane movements, the M.E.11 is a new mobile 8-ton crane produced by Thomas Smith and Sons (Rodley), Ltd, Rodley, Leeds (Stand 78). The six-wheeled chassis may be driven on four or all wheels, and the basic 25-ft. boom can be extended to 65 ft. Power-lowering equipment for accurate positioning may be specified. The machine can be used to operate a digger as an alternative to craning.
• Four models of a new range of 15 types of 6-45-ton Coles crane appear on Stand 57. Diesel-electric transmission has been incorporated by the makers, Steel's Engineering ProductS; Ltd., Sunderland, in these new-designs. •The engine of the prime mover is directly coupled to a variable-voltage generator which supplies current to the individual motors for the different craning movements.
The cranes revolve on large-diameter rings of double ball bearings‘obviating need for a centre post and affording better load distribution. Some models are self-propelled and others are lorry-mounted. The smallest, the 5510, can lift 6 tons at 7-ft. radius with a 25-ft. jib, whilst the S5012 can raise 45 tons at 10-ft. radius with a 50-ft. jib.
