A pivot-forming crane element for a rotating portion of an element-mounted crane includes a framework on which a motor-driven orienting system, a hoisting winch and a dispensing winch are mounted. The motor-driven orienting system includes a pivot mechanism about an orienting axis and at least one orienting electric motor cooperating with the pivot mechanism to make the framework pivot about the orienting axis. The hoisting winch is provided with a hoisting electric motor cooperating with a hoisting drum around which a hoisting rope is wound. The dispensing winch is provided with a dispensing electric motor cooperating with a dispensing drum around which a dispensing rope is wound.

A holding device for use with a telescopically extensible crane boom (57) in order to keep a load handling tool (4) in a given parking position in relation to the crane boom. The holding device (1) comprises: an attachment (10) to be fixed to an end of a telescopic crane boom section of the crane boom; a tool holder (15), which is detachably mountable to the attachment (10) and configured for engagement with the tool in order to support it against the crane boom and keep it in the parking position, the tool holder being provided with a sliding member (28), through which the tool holder is configured to slidably rest against an external surface on the crane boom; and a locking mechanism (16) for locking the tool holder and the attachment to each other when the tool holder is mounted to the attachment.

Hoists, platforms and davits are described as well as methods of securing same to telecommunication and other towers. The hoists, platforms and davits may be secured to the towers on a temporary basis using clamps. The clamps may include brackets and cables. The cables may be attached to the brackets, may wrap around the outer surface/perimeter of the tower pole/leg and may use tension to keep the bracket in place.

A crane for lifting and transporting loads includes a base frame for transferring the loads of the crane onto a support surface by a plurality of wheels. The wheels are capable of rotating relative to the base frame so as to change the camber angle of the wheels.

A crane, in particular a pick and carry crane, may have a front chassis with front wheels and a back chassis with back wheels, the front chassis being articulated relative to the back chassis so that the crane can travel whilst carrying a load suspended from a boom. The back and front wheels have independent suspensions which are capable of connection to one another so that movement of a left wheel influences movement of a right wheel, thereby improving the handing of the crane, particularly over rough terrain.
