A Frame Gantry Crane Design
A frame gantry crane is mainly composed of gantry frame, hoist trolley, running mechanism and electric control system, of which the gantry frame consists of main beam, end beam, supporting legs, end carriages, trolley track and so on.
Steel is the main substance used to fabricate gantry cranes, and carbon steel Q235 is commonly adopted to manufacturer the metal structure of the crane that does not require very high strength. For the high tensile strength and great yield limit requirements, low alloy high strength structural steel Q345 will be employed.
The gantry crane is usually equipped with electric hoist, such as wire rope hoist and chain hoist to help save manpower and improve the efficiency of lifting operations. This electric gantry crane is generally operated by a driver sitting in the crane cabin or a worker from the ground. It can also adopt a combined operation method, such as cab control and wireless remote control, but these two methods cannot be used simultaneously.

With regard to running mechanism, the gantry crane can be designed into rail mounted and mobile type. The rail mounted gantry crane has a fixed rail path, whereas mobile gantry crane can achieve a more flexible lifting movement. It can be either wheel mounted or rubber tyred type.
To realize an optimal performance, the A frame gantry crane supplied by our company is designed with anti-swaying device, anti-collision device, limit switch and so on. For open-air uses, the gantry cranes are suggested to be outfitted with rain cover, windproof and anti-slip device to prevent the damage of the equipment and components as well as fatal accidents.

How to Take Care of Your Gantry Crane?
Inspections and preventive maintenance enable you to keep a close eye on the equipment wear and tear so as to avoid crane breakdowns and property losses. Therefore, a periodic inspection such as once a month and once a year should be conducted.
For some critical components that directly affect the performance of the crane, a frequent inspection and preventive maintenance should be done to make sure they are in good working conditions. However, many crane users are unsure as to which is the best frequency for inspection and maintenance. There are a few factors determining the frequency of inspecting and serving your crane, including A frame crane design, frequency of use and environmental conditions. To determine a proper frequency, the crane users should monitor the actual machine usage and watch for the signs of wear.
In addition, gantry crane operator training is essential as most crane accidents result from human errors. Improper usage will not only lead to premature wear and breakdown, but cause serious and even fatal accidents. Therefore, crane operators should be deemed competent to operate the equipment and strictly follow operation manuals and rules.
