The motor transmits the power to the drum wound with wire rope through the reducer to achieve the lifting and lowering of the container; the electric drive realizes the deceleration; the disc brake is braked by hydraulic and electrical control; the position indication system realizes the depth indication of the container; The combined control system of machine, electricity and liquid composed of various sensors and control elements realizes the monitoring and protection of the whole machine; the computer and network technology are used to realize the transmission of information inside and outside the machine.
1. Adopt integral, two-lobed and four-lobed reels;
2. The reel rope groove adopts spiral rope groove pressed by engineering plastic lining, and a steel rope transition device is arranged between the layers;
3. The rear disc brake of the oil cylinder is adopted, and the electric-hydraulic joint control is adopted; the hydraulic station is divided into two types of medium pressure and medium and high pressure. The medium-pressure hydraulic station has two types of constant braking force electrical delay and hydraulic delay two-stage braking; the medium-high pressure hydraulic station has two types of constant deceleration and constant braking torque two-stage braking. The hydraulic station can be equipped with pressure sensors and pressure relays;
4. The main shaft and the reel are connected by a plane large torque friction;
