Spreader Beam (Spreader Bar)

Converts single lifting point to double or multiple lifting points, uniform force on the load and keeps it horizontal, avoiding tilting, bending deformation or slipping of long objects during single-point lifting, especially suitable for horizontal lifting of easily-deformable long objects such as steel beams, plates and concrete components.

A single crane hook can achieve double or multiple lifting point lifting through the balance beam, no need for double-hook cranes, reducing equipment cost; the number and spacing of lower lifting points can be flexibly configured according to load size, weight and center of gravity, adapting to long objects of different lengths and shapes, with extremely strong versatility.

Adjustable lifting beams have lower lifting points movable along the main beam chute, adapting to loads of different lengths; telescopic lifting beams have extendable main beams, further expanding the applicable length range; one lifting beam can replace multiple fixed-length lifting beams, reducing sling quantity and storage space, especially suitable for multi-variety, small-batch lifting occasions.

Main beam adopts I-beam or box beam welded structure, 经过 strength calculation and heat treatment, with good rigidity, strong load capacity and small deflection; equipped with safety pins, anti-fall baffles and other protection devices, reliable lifting point connection; safety factor ≥4 times, tested via 1.25× rated load static test, ensuring safe heavy-load lifting.

Using the balance lifting beam can quickly complete horizontal lifting of long objects, no need to repeatedly adjust lifting points and center of gravity, loading/unloading time shortened by over 50%; avoids rework and damage caused by load tilting deformation, reducing lifting loss; one lifting beam adapts to multiple loads, reducing sling procurement and storage costs, with significant comprehensive economic benefits.
