Large-load take-up and pay-off machine applied to take-up and pay-off of steel wire cable

The utility model discloses a large-load take-up and pay-off machine applied to take-up and pay-off of a steel wire cable. The large-load take-up and pay-off machine comprises a rack, a hydraulic motor, an electro-hydraulic directional valve, a throttling valve a, an electromagnetic directional valve, a throttling valve b, an overflow valve, an anti-explosion remote controller, an oil tank, a one-way breather valve, a winch, a protection plate, a wireless transmission meter counter, a wireless transmission weighing instrument and a lifting lug. According to the utility model, people can be helped to switch the winding direction of the cable on the wire coil in a long cable test, and the influence of inductance generated by winding the cable in the same direction on the test and equipment is reduced. And meanwhile, people can conveniently switch the driving scheme according to whether electricity can be used on site or not. 本实用新型公开了一种应用于收放钢丝电缆的大载荷收放机，包括机架、液压马达、电液换向阀、节流阀a、电磁换向阀、节流阀b、溢流阀、防爆遥控器、油箱、单向呼吸阀、绞盘、护板、无线传
