The "Stable Anchor Point" for Heavy Lifting: Fixed Double-Hook Lifting Beams
When hundreds-ton workpieces require precise repositioning, and when the lifting of large equipment allows no room for deviation—fixed double-hook lifting beams are the "power partner" of heavy-duty double-girder bridge cranes, ensuring stable and precise lifting operations in heavy workshops.

Its integrated, fixed beam structure provides a solid foundation: eliminating the risks associated with movable connections, the high-strength alloy steel welded beam allows for direct transmission of the force line of a hundred-ton load. During lifting, the beam remains stable and undeformed, ensuring the posture of heavy workpieces remains controllable, fundamentally avoiding the risk of displacement during large-scale lifting.
The collaborative design of the double hooks perfectly matches the lifting logic of double-girder bridge cranes: the two hooks evenly distribute the load, reducing the stress on a single hook and ensuring a more balanced lifting posture for long, heavy equipment—whether it's giant forgings, large tanks, or ultra-wide steel structures, lifting and repositioning can be completed in a horizontally stable state, eliminating the risk of unilateral force.
Its seamless compatibility with heavy-duty double-girder bridge cranes allows it to be used immediately upon attachment: no additional interface adjustments or modifications are needed; simply attach the crane hook and it's ready for high-load operations, perfectly meeting the fast-paced lifting demands of heavy manufacturing workshops.
It's more than just a lifting tool; it's a "safety redundancy" for heavy-duty workshops—the low failure rate of its fixed structure and the balanced load-bearing capacity of its double hooks transform 100-ton lifting from a "high-risk operation" into a "standardized procedure," accelerating the turnover of heavy workpieces while maximizing safety.
Fixed Double-Hook Lifting Beam (for heavy-duty double-girder bridge cranes) Core Application Scenarios:
It's a "on-demand" lifting partner in heavy manufacturing workshops, precisely matching high-load, high-requirement operating scenarios:
1. Heavy Machinery Plants: Lifting Hundred-Ton Forgings
When handling large forgings (such as rolling mill stands, marine crankshaft forgings) produced by 10,000-ton presses, the fixed double-hook lifting beam evenly distributes the load through its two hooks. The integrally welded beam has no connection gaps, ensuring the forging remains stable and does not tilt during lifting, avoiding damage from impacts and reducing the safety risk of single-hook overload.
2. Pressure Vessel Workshops: Lifting Large Tanks/Heads
For thin-walled pressure vessel tanks with a length-to-diameter ratio > 5 and ultra-thick heads, the double-hook lifting beam maintains the workpiece's horizontal position, preventing tank deformation caused by single-hook lifting. The low sway of the fixed structure ensures that tank interfaces and welds are not subjected to additional stress during lifting, meeting the precision manufacturing requirements of pressure vessels.
3. Steel Structure Production Workshop: Lifting of Extra-Wide Heavy Steel Components
For extra-wide (≥3m) heavy components such as main steel beams for factory buildings and steel box girders for bridges, the hook spacing of the double-hook lifting beam can be adapted to the width of the component, evenly supporting both ends of the component. Combined with the span of the double-girder bridge crane, this ensures stable movement of the component from the welding table to the painting station, eliminating the risk of lateral bending.
4. Heavy Equipment Assembly Workshop: Transfer of Large Machine Tools/Complete Sets of Equipment
In the assembly/transfer operations of large CNC boring machines and complete sets of rolling mill equipment in the workshop, the fixed double-hook lifting beam seamlessly adapts to the crane, ensuring smooth start-up and stop without impact. It allows for precise control of the equipment's lifting posture, preventing damage to precision components due to shaking.
