Overhead crane is Hengjia in workshops, warehouses and empty field for material lifting material lifting equipment. Because of its ends located in the tall concrete pillars or metal bracket, shaped like a bridge. Overhead crane overhead bridge along the laying of tracks on both sides longitudinally running, you can take advantage of the space under the bridge lifting material from ground equipment obstacles. It is the most widely used, the largest number of a lifting machinery.

Gantry crane installation importance and characteristics
Since gantry crane is a special equipment, with higher risk characteristics, therefore, the gantry crane installations, security is particularly important to pay special attention to the following aspects:
(1) gantry cranes are mostly large structure, institutional complex mechanical devices, it is often difficult overall transport is often split after shipping the equipment to use the site as a whole assembly. Therefore, it is necessary in order to reflect properly installed crane overall eligibility to test the integrity of the whole crane and integrity.
(2) gantry cranes are used venues or buildings in orbit. Therefore, its orbit or install base, and the hoist crane itself, is able to complement each other well, and the ability to run whether they can adapt to meet strict requirements, must go through the proper installation and post-installation commissioning and testing concluded .
(3) Cranes high security requirements, safety devices must be complete and properly installed, in order to achieve a reliable, flexible, and accurate technical requirements.
(4) based on the importance of safe working crane, the crane was put into use in order to meet the operational requirements of various loads, it must be conducted according to the provisions of the crane load, full load, overload static and dynamic load tests. These tests must be the operating state of the crane mechanism or specific for a stationary state. This requires the crane load test after installation only after the transfer of use.
(5) gantry crane wire rope and other flexible member, and many other parts will occur in some of the initial elongation under load, deformation, loosening. It also requires the hoist gantry crane installation, commissioning loaded after correction for repair, adjustment, handling and fastening. Therefore, we must do a good job crane installation, commissioning, speed and a series of work in order to ensure the future safety of the crane normally used.
