Tower Crane Knowledge sharing：

Technical analysis of steel-speed adjustment of lifting mechanism of Tower
 Can produce a variety of tower crane model products, tower crane equipment, accessories, the factory has advanced tower crane research and development, production technology. Here, with the majority of Tower hoist users to discuss the tower hoisting mechanism with the steel-speed adjustment.
1. Rotor string electronic speed regulation of winding motor
This kind of speed regulation can change the speed of the motor by connecting the variable resistor in series in the rotor winding, and using the operation handle to send the main signal to control the contactor, so as to switch the resistance to change the speed of the motor, so as to achieve the requirements of smooth start and uniform speed regulation.

Some winding motor rotor string electronic speed adjustment, but also can increase the electromagnetic shift gear reducer, this way can use speed adjustment to double the number of stops.

2. Variable speed regulation
By changing the extreme number, the rat cage motor can obtain the working speed of the upper and lower gear and the slow positioning speed of the first gear. Basically, it can meet the speed regulation requirements of the tower crane and simplify the mechanism.

However, the impact of the gear shift is large, and the speed regulation range is 1:8. About, And can not run at low speeds for a long time. It is mainly used for light and small tower cranes below 40t.m.

The variable pole speed adjustment can also be added to the electromagnetic shift reducer to double the number of speed adjustment gear. This speed adjustment is mainly applied to the tower crane with lifting capacity of 450-900 kN.m.

3. Double speed winding rotor string resistance speed adjustment

The motor has two kinds of pole logarithm, which are regulated by two ways: string resistance and pole change.

 4. Double motor drive speed adjustment
This kind of speed regulation application is to use two winding type motor drive. The two winding motors are connected by a gear with a speed ratio of 1:2, one as a drive motor, and the other as a brake motor.

Double motor speed adjustment can also be driven by a winding motor plus a cage motor or two multi-speed cage Motors, which can obtain different speed regulation characteristics.

This lifting mechanism can speed up during load movement, and can achieve airborne descent at maximum speed, thereby improving production efficiency, lifting can be accurately in place, work smoothly, and have a large speed range of 1:40. However, the mechanism is relatively complicated, and its transmission parts need to be specially designed and manufactured. Mainly used in large and medium-sized tower hanging.

The Causes and Solutions of Serious Fault of Twisted Arm and Twisted Tower
The factory is engaged in tower crane design and production for many years, tower crane technology advanced, reliable quality, can produce a variety of models, provide the latest and most complete various types of tower crane prices.

Through this article discuss with everybody, how does tower crane frame and tower body twist pendulum serious do? The cause and solution of serious fault of Crane frame and torsional pendulum.

1. Fault causes: speed reducer failure.
Solution: overhaul speed reducer.
2. Fault causes: Hydraulic couplers overcharge.
Solution: bet according to the manual.
3. Fault cause: gear gear gear or rotary support poor.
Solution: rest.
