What are the precautions for daily use of double beam gantry cranes:

As a manufacturer of bridge cranes in Shandong, today the editor will explain to you the precautions for daily use of double beam gantry cranes. Interested friends, let's learn together!

The casing of all powered parts of the double beam gantry crane should be equipped with reliable grounding devices to prevent unexpected safety accidents. The track of the car is not welded to the load-bearing beam by electric welding, and an electric welding grounding device should be used. The track of the large vehicle and the step-down transformer should be grounded on the bottom voltage side according to the drawing requirements. The above grounding devices should be inspected on time. The electrical equipment of outdoor gantry cranes must have excellent waterproof and rainproof devices.

The ladder, service platform, and aisle on the gantry crane should be equipped with protective railings of no less than 1 meter, with a total width of no less than 600mm, and equipped with partitions of no less than 150mm. When the relative height of a straight ladder or an inclined ladder with a tilt angle exceeding 75 degrees is higher than 5M, an arc-shaped safety protection ring should be installed. When the vertical ladder exceeds 10 meters, there should be a stair platform with guardrails every 5-6 meters.

When there are some people on the gantry crane, it is strictly prohibited for the driver to reclose and start the lifting equipment. During maintenance, the driver must follow the guidance of the maintenance personnel. The working address of the gantry crane should have sufficient lighting equipment and unobstructed lifting safety passages. It is prohibited to throw objects downwards from the gantry crane. Staff unrelated to work are prohibited from stepping onto the gantry crane at will. The wooden floor of the cab should be paved with rubber sheets or other insulation materials.

Drivers should master the structure, characteristics, and principles of gantry cranes, and carry out safety production technology testing, maintenance, and lubrication of key components on time. Familiarize and strictly follow the operating procedures to ensure safe lifting. Drivers must enter and exit the cab by climbing the ladder to the left and right, and it is strictly prohibited to exceed the guardrails and handrails with special tools.
