Title: Mobile support for jib cranes, in particular railway-mounted cranes
Inventor: BENDIX HORST PROF DR ING
IPC: B66C23/78
Filed: 1983-01-26
Abstract: The invention has the object of providing a mobile support with a minimum degree of expenditure, with which the jib crane is upgraded and its useful properties improved. The object of the invention consists in avoiding the manufacture of special, mobile support elements and using the transport vehicles which already have to be present to transfer the jib crane under certain conditions. According to the invention, the object is achieved in that the transport vehicles used for rail transport are used during the operation of the crane as carrying and travel elements. These support vehicles have devices for absorbing the vertical and horizontal forces in order to compensate track spacing differences and to compensate unevennesses in the plane of the track. In order to favourably apply the support forces, the support points are arranged over the bogie pivots of the pivoted bogies.

Patent DE-3342271-A1 (DE)
Title: Hydraulic control arrangement
Inventor: RASPER MANFRED ING GRAD
IPC: F15B11/08
Filed: 1983-11-23
Abstract: The control arrangement has a pump (11) which serves to supply a single-acting working cylinder (17). The latter is controlled via a reversing valve (31) and a directional control valve (25), both of which are actuated by one and the same electromagnet (36). When the working cylinder (17) is extended, the directional control valve (25) is hydraulically held by the pump pressure in operating position (I), which forms a blocking function through a non-return valve (28), although the electromagnet (36) is switched on, which at the same time controls the reversing valve (31) in blocking position (II). When the electric motor (10) and the electromagnet (36) are switched off, the directional control valve (25) remains in blocking position (I), although there is no longer any delivery pressure, while the reversing valve (31) is controlled in flow position (I). The pressure medium still delivered by the lagging electric motor (10) flows off into the container (13) via the opened reversing valve (31). Thus exact positioning of the working cylinder (17) is possible. <IMAGE>
