Gantry Crane Wheel Design

2021-04-16|Product News

With the continuous improvement of production levels, the role of lifting and transport machinery has gone beyond being used as auxiliary equipment and has thus been directly applied in the production process, becoming an integral part of the main equipment on the flowing production line. In order to better adapt to the large hydropower construction projects in the construction of dams, applicable port loading and unloading work, large open-air factories and construction sites installation. The fittings and use of gantry cranes are vital.

To understand the use of machinery and equipment, you should first have an understanding of the equipment structure. The movement of gantry cranes depends on the role of the wheel set. The design features of the gantry crane wheels include the following.

gantry crane wheel

The wheels are used to support the load of the electric hoist gantry crane and to make the crane run back and forth on the track. The main forms of wheel damage are wear, hardened layer crushing and pitting. The material used for the wheels is generally ZG430-640 cast steel. In order to improve the wear strength and life of the wheel surface, the tread surface should be surface heat treatment, requiring a surface hardness of HB300-350, quenching depth of not less than 20mm.

Portal crane wheel set: crane running mechanism wheel level deflection value is an important technical parameter of the crane, deflection value exceeds the poor will cause whistle track, increase the running resistance, vibration and noise, aggravate the track and wheel wear, greatly reducing the service life of the crane, so all kinds of crane manufacturing technical conditions are to the wheel level deflection provisions allow the value.

Wheel set structure: The application of the control of the horizontal deflection value of the wheels of the running mechanism is mainly based on different product structures to take the appropriate technical measures. The more commonly used, process measures are also relatively simple design structure is: the wheels are assembled to the bracket to form a wheel set, for example, angular bearing box wheel set and trolley type 45° split bearing box wheel set, in the main structure of the crane, installed to adjust the horizontal deflection of the wheels after the appropriate fixed.
