Unit 12

Ex.4: E.g. Kirow’s cranes – carrying a jib and other necessary hoisting and controlling equipment, for work with, wheels of the pneumatic type, working below rail level and at boom heights beyond 15m, without a separate counterweight, useful in areas with limited space;

other types of cranes –for work with, rope-operated, not high, etc.

Ex.5: mobile – fixed, hydraulically operated – rope operated, prefer – not to be overfond of, high – low, better – worse, handle – bring down, versatile – one-sided, steel – wooden, available – unavailable, out – in

Ex.6: Various types of cranes are available, the type and size best suited for a specific operation being influenced by the following factors: the nature of the work on which it is to operate, the weight of load it has to handle.

Cranes of this type usually take the form of a frame carrying a jib, a winch, and other necessary hoisting and controlling equipment, the whole being mounted on a cast-iron bed plate fitted with road wheels of the pneumatic type.

At present rope-operated mobile cranes are being superseded by hydraulically operated ones in which all working operations but traveling are performed with the help of hydraulic rams.
