Gantry cranes are common industrial lifting equipment with a high site utilization rate. Gantry cranes are also called frame cranes or portal cranes, which are divided into single girder gantry cranes and double girder gantry cranes. They have a large working range, wide applications, and strong versatility. A gantry crane is indispensable lifting equipment for port freight yards. Gantry cranes must be operated by professionals. Pay attention to safety during the operation. Next, we will give you a detailed introduction to how to properly maintain the single girder gantry crane and double girder gantry crane, and what the precautions are for use.

How to properly maintain the single girder gantry crane and double girder gantry crane

• The main metal structure and main parts of the single girder and double girder gantry cranes can be inspected. Check whether there are welding cracks in the connecting welds and whether the main beam has residual deformation and instability. If problems are found, operations should be halted and corrected.
• When we inspect the single girder gantry crane and double girder gantry crane parts, we should pay attention to whether there is dirt or wear and tear. The wire rope should be lubricated regularly, and the dirt should be checked before lubrication. If some parts are seriously damaged, they should be replaced in time.
• More attention should be paid to the maintenance of the electrical part of the single girder gantry crane and the double girder gantry crane. For example, check whether the motor and wiring can be properly grounded.
• If the single girder gantry crane and double girder gantry crane are not used, the equipment needs to be placed in a dry and clean environment to prevent corrosion and blockage due to moisture and dust.

What are the precautions for the use of gantry cranes?

Single girder gantry crane and double girder gantry crane are a variant of bridge crane, also known as gantry crane, which is suitable for outdoor cargo yards, material yards, bulk cargo loading, and unloading, etc. Its metal structure is similar to a door-shaped frame. There are double-leg supports under the main beam, which can directly walk on the ground track. The two ends of the main beam can be equipped with outrigger cantilever beams.

• After the gantry crane operation (assembled type) is completed, carry out load test lifting (test lifting is divided into static load test lifting and dynamic load test lifting) and check the working capacity, carrying capacity, stability, and reliability of each system.
• Not everyone can operate the single girder gantry crane or the double girder gantry crane. They must be trained and obtain corresponding certificates before they can operate. Every time before driving, check whether the machine equipment is in good condition and whether there is any fault, and carry out safety inspections and maintenance on the equipment frequently.
• The work should be directed by specialized personnel, and other personnel should have a clear division of labor, and there should be no multi-person command.
• In special circumstances during operation, the heavy object should be slowly lowered to the ground to avoid suspension.
• When the gantry crane is working, it is strictly forbidden for people to stand below.
• When two gantry cranes lift an object at the same time, they should obey the command and keep pace.
• If there is a thunderstorm during work, stop working and cut off the power supply.
• After the operation is completed, the single girder gantry crane and double girder gantry crane should stop at the designated position, the upper, front, and rear of the lifting hook should be fixed with pads, and the power should be turned off.
