The Mechanical Handling and Storing of Material

TR ANSPOR TERS, BRIDGE OR CANTILEVER CRANES 441 These transporters command a range of travel of 1/0 ft. and are for loads of tons. They are used for shipping military stores at the Royal Arsenal. Temperley Patent Grab Transporters.—The more general advantages of a Temperley transporter are accentuated when the hoisting and transporting of material in bulk is effected by means of high speed grab machinery. These transporters are accordingly fitted with hoisting and transporting machinery, by means of which the operations of hoisting and lowering and that of transporting may be carried on separately or together without either operation in any way influencing or interfering with the other.

The load may thus be carried along the shortest trajectory from the point where it is picked up to that where it is delivered. The same machinery also gives complete command over opening and closing of the grab, these operations being effected either quickly or slowly in any desired position at the will of the operator. The grab may thus be lowered close down to the stock heap, and the material deposited with little breakage or dust. 1 he hoisting or lowering and the transporting may be conducted at varying speeds, and the grab may be transported either open or closed.
