  • Tower cranes in construction, delivery, the logistics industry is essential staple goods handling equipment, tower and so heavy handedly crushing part is lifting mechanism, the performance and quality directly reflect the performance of the tower crane good or bad. At the same time, it is also the largest tower crane three organs of institutions of power, mainly composed of motor, gear, brakes, chassis and so on.
     
    First, let's look at the lifting mechanism in the motor section - tower crane used motor type and quality of decisions tower crane lifting performance, at present, widely used in lifting motors are: multi-speed motor, winding motors, variable frequency motor. Its performance and prices are rising by one, the same type of process is different from different manufacturers, their quality and price varies widely.
     
    Then, the tower is an integral part of the gear - currently a multi-level multi-tower cylindrical gear reducer, but because the market is very competitive, a different business philosophy is not the same, using the production process different, their quality and price vary widely. According to my understanding, some of the speed reducer factory in order to meet the needs of low-cost market, gear does not make heat treatment and surface treatment, this way, the performance of the product simply can not be guaranteed, life greatly reduced, soon appeared a lot of noise Case
     
    In addition, the reliability of the tower crane brakes in lifting mechanism is a direct impact on the safety performance of the tower crane, the choice of the manufacturer of concern. The tower crane with a metal frame structure is similar, the main role is to provide physical support for the lifting mechanism, its structure and the selection is reasonable also need attention.
