Abstract

The problem solved by this invention consists in producing a workover installation, having remote controlled reversible electric actuation, without pneumatic system, having only one velocity step, with no-shock running and energy recovery. The technical solution consists in supplying the direct current electric motor (10), by converter, with operation with four dials (13). The supplying of a direct current electric motor excitation takes place through a simple controlled bridge (15), the automatic limitation of the speed thereof on the descending sense taking place depending on the handled load (4). The automatic actuation of the security brake assembly (2) is done at each load stop, with a delay determined by the delay relay (18) and, instantaneously, in case of failure, power failure, exceeding the crane reserve stroke or exceeding the admitted peak load.
