Compared with traditional mining hoisting winches, it has six major advantages
advanced technology
The new generation of permanent magnet synchronous speed regulation technology has a speed range of 0.01Hz~15Hz, which is 100 times more accurate than traditional hoist speed regulation, making the operation of mining hoist winches more stable.
safe and reliable
In the event of a system power outage and brake failure, the hoist can automatically enter a power generation state, generating electrical energy to slowly lower the mining hoist winch, fundamentally preventing the occurrence of runaway accidents.
Small size, light weight
The permanent magnet embedded mining hoisting winch has lost control of the reducer. Couplings, lubrication stations, and motors are installed inside the drum, reducing the weight of the main engine by 45% and the footprint by 50%. Equipment transportation and installation are more convenient, and infrastructure investment is significantly reduced.
energy conservation and consumption reduction
The permanent magnet built-in mining hoisting winch eliminates the power loss of reducers, couplings, and lubrication stations, and improves work efficiency by 15%. In addition, its characteristic of being able to feedback to the power grid under any load conditions can achieve a comprehensive energy saving of up to 30% compared to traditional mining hoisting winches.
Quiet and low noise
The noise level of the permanent magnet built-in mining hoisting winch can be as low as 60dB, achieving a quiet and comfortable operating environment in the machine room.
Low maintenance volume
The technology of permanent magnet motor is mature, with extremely low failure rate. At the same time, without the maintenance work of reducer, coupling and lubrication station, the daily maintenance of permanent magnet embedded mining hoisting winch is greatly reduced.
