Drive, control and speed
The motor is a permanent magnet brushless maglev unit built to industrial grade, and damage to it is not easily done. Sites run either 110V or 220V single phase, and both are offered. High power and high efficiency mean that long time working is the normal mode rather than the exception. Protection covers temperature and overload, and speed is regulated stepless. The enameled wire tolerates 200 °C, and working capacity comes in 50% above the ED series.
Electronics are capacitor-free and commanded by an SCM, so performance holds stable and the power factor stays high. Plug and pull wiring is what makes operation straightforward and maintenance reliable.
Stopping, and what triggers it
Mechanical ratchet braking and resistive short-circuit control are combined in a dual braking system. Sintered brake linings of high friction coefficient are what keep the motor durable. A power failure, or a winch failure, brings braking immediately, and the outcome is high safety with a long service life.
The limit switch takes over at the top of travel: if the hook reaches a certain lifting height, or the wire rope is reversed, it is triggered to protect the machine and to stop it working.
Wire rope comes from a top imported brand, and its safety factor is 4 times that of ordinary machines.
Gear train, housing and finish
A high efficiency bevel drive reduction gear performs the reduction. Gears of this type go through special heat treatment and end up three times stronger than ordinary products.
Motor and gearbox sit in one aluminum alloy die-casting structure of strong toughness. CNC machining at high precision is what makes the running of the winch smooth and its noise low. The surface is powder coated to automobile grade for a nice appearance, and the unit stays compact.
