Abstract

Hydraulic rotate system for swing crane, which essentially is constructed with hydraulic motor (A), blend (B), two-ways valve (C) and steering valve (D). Blend (B) releases oil through, when the circuit supply of the crane is interrupted and allows thereby automatic the boom of the crane to place itself in the direction of the wind. By normal operation the shunt effect of blend (B) can if desired be eliminated through the valve (C), which is steered from the manoeuvring organ in case standstill braking is wanted by stop or powerful start of the rotate movement.
