Abstract (en)
[origin: EP0291700A1] The invention relates to an inclined hoist with a truck which is guided on guide rails of the hoist and can be moved to the opposite roof side preferably via a cranked piece arranged in the ridge area of a building. The essence of the invention consists in the fact that a return winch is allocated to the material winch, the hydraulic control being made in such a way that the motor to which pressure fluid is admitted in each case draws the other respective motor with it, which turns off in a throttled manner in the closed circuit. In this arrangement, the circuit is made in such a way that only one spool valve is required. <IMAGE>
