What Is a Crane Girder?

Beam crane is a kind of crane. It is a crane composed of a bridge and a crane. The bridge moves longitudinally along the ground track, and moves laterally along the bridge. There are three working mechanisms including lifting, bridge walking and trolley walking. Driven by human or electric power. Mostly used to move goods in the factory building or workshop. It is used for lifting goods on different occasions such as factories, warehouses, stockyards, etc. It is prohibited to use in flammable, explosive and corrosive media environments.

Working institutions include:

1. The maintenance crane must be operated by a specially trained person and approved by the competent authority.

2. Crane operators must be familiar with the mechanical and safety performance of the cranes they operate. They must be familiar with and strictly implement crane operation regulations and safety regulations. They must be proficient in lifting operation skills. They must concentrate on their operations, obey commands, and operate with caution.

3. When operating the crane, the operator must obey the command of the commander, and the emergency stop signal should be executed immediately by anyone.

4. Every time before using the crane, the operator must first check the brakes of the crane,

Beam cranes should be checked on both sides before use

During use, inspect the machine every time to observe whether the machine has abnormal sounds and whether the operation performance is sensitive. When the hook is in the lowest working position, the wire rope on the drum must retain more than 3 safety rings. Jog the button, and observe the axial movement of the motor shaft visually, it should be within 1 ~ 2mm. Check whether the hook head rotates flexibly and whether the bearing is replenished every week. Regular monthly check

The operator must abide by the "No Ten Hangs" principle under any circumstances to prevent accidents. Before lifting, make sure that no one is crossing or standing in the moving area. Take the hook in the correct position, pay attention to check whether the hook is secure and secure, and lift the personnel after leaving the proper safety distance. Lifting speed and height should be appropriate, and movement should be slow and stable. During hoisting operations, the driver must cooperate with the ground commander to make the lifting, walking speed, and stopping as consistent as possible, and only one person can command at the scene. Sufficient lighting should be provided at night for lifting operations. During hoisting operations, hoisting must be performed according to the specified load, and overload operation is strictly prohibited. It is strictly forbidden to stand, pass or work under the suspended weight. When dangerous situations such as wire rope breakage, hanging objects fall, or failures occur during lifting, the machine shall be shut down in time for handling. Do not continue the lifting operation until the cause is found and the failure is eliminated. Maintenance and repairs are not allowed while in operation. If there is any abnormal noise during use, follow the procedure of stopping first, checking later, and removing the fault before driving. ^[4]
