Lifting Beam for Handling Large Power Equipment

The lifting beam (balance beam) used to lift large power equipment (such as transformers, generators, switch cabinets, etc.) is a lifting tool designed specifically to disperse the load and keep the equipment horizontal and stable. Its core function is to convert the single-point load of the crane hook into a multi-point evenly distributed load through the beam structure, avoiding deformation or damage of the equipment due to uneven lifting force. 

Core design adapted to power equipment
Uniform load distribution
Large power equipment (such as transformers, which can weigh up to 50-500 tons) are mostly rectangular, with a high center of gravity and easy to deflect. The following designs ensure uniform load on the hanging beam:
The lower hanging ears are symmetrically distributed (the spacing matches the equipment hanging point), so that each wire rope/chain is subjected to the same force;
The main beam section is designed as an "I" steel or box structure with high bending strength. The deflection during hoisting is ≤L/1000 (L is the length of the hanging beam) to avoid equipment tilting.
Protect equipment integrity
When the lower hanging ear is connected to the equipment hanging point, a flexible connection (such as adding rubber pads and using shackles) is used to avoid deformation of the equipment casing due to rigid collision;
For equipment without hanging points (such as large switch cabinets), the hanging beam can be used with special clamps (such as clamps, support arms) to disperse the pressure through multi-point support to prevent excessive local force.
Anti-overturning and stability
The length of the hanging beam matches the length of the equipment (usually slightly longer than the equipment), ensuring that the center of gravity of the equipment is at the center of the hanging beam during lifting to reduce shaking;
Some hanging beams are equipped with a level or inclination sensor to monitor the horizontal state of the equipment in real time and issue an alarm when abnormalities occur.

Application scenarios
Transformer installation: Lifting oil-immersed or dry-type transformers (weight 50-300 tons), lifting the transformer horizontally through the lifting beam to prevent the internal winding from shifting;
Generator stator lifting: Large generator stators (weight 200-500 tons) need to be lifted by lifting beams and special lifting equipment to ensure that the stator core is not deformed by force;
Switch cabinet transportation: When the complete set of switch cabinets (weight 5-20 tons) has no standard lifting points, the lifting beams are used with clamps to achieve multi-point support to prevent the cabinet from deformation;
Wind power equipment lifting: The wind turbine nacelle (weight 50-100 tons) balances the load through the lifting beam to ensure a stable lifting process.
