BridgeCraneBridge cranes are widely used in various industries, primarily for the loading and unloading of materials. The hook is a crucial component of a bridge crane, often suspended on the lifting section's wire rope with the help of pulley sets and other parts. When selecting a hook for a bridge crane, it is advisable to choose high-quality products from professional manufacturers. Below,Shandong CraneIntroducing the operational requirements and precautions for the double girder overhead crane.
It's well-known that double girder cranes play a significant role in everyday life. Due to various factors, especially safety requirements, they must adhere to relevant regulations during operation.
1. Operators of double girder overhead cranes must pass an assessment and obtain an operation certificate before they can operate the machinery. Additionally, all personnel involved should carefully read the usage manual provided by the crane manufacturer before using the product.
Each crane should be equipped with a work diary and a mechanical service record book to document the crane's operational activities, facilitating handover checks and maintenance, and simultaneously, routine and regular maintenance should be conducted for double girder cranes as required.
3. Operators must correctly understand the relationship between the working range and lifting capacity of the double girder crane during operations. It is strictly prohibited to overload or lift beyond the crane's range. Operators must know the weight of the cargo being lifted and perform a no-load operation test on the lifting, lowering, swinging, rotating movements, and other safety devices. Only if no abnormalities are found may the lifting operation commence. During the operation, drivers should remain focused and closely monitor the ship's situation. A signal must be given before lifting cargo or changing the cargo's direction of movement.
4. During operation, cranes are strictly prohibited from lifting cargo over people's heads. Operators must strictly adhere to the "Safe Lifting" procedure, which involves lifting and straightening the rigging, aligning it with the centerline, and then safely lifting the cargo. The use of tow hooks is strictly forbidden. Operators should carefully listen to the mechanical sounds during work and immediately stop the crane upon detecting any anomalies, resuming operations only after the fault is resolved.
