Crane lifting beams are below-the-hook devices used to maintain and sustain weight during a Weihua overhead crane lift. The device’s primary purpose is to maintain the raising slings just under the beam at a 90° angle or near it. Therefore, the force should be straight to the vertical in this case.
In terms of its objectives and design, hoisting and spreading beams are frequently confused. The two, therefore, are technically distinct. The difference lies in the sort of force delivered to the beam. Although the load on a raising beam causes the beam to bend, the load on a spreading causes the beam to be compressed.
A lifting beam has a straightforward design, consisting of a beam with a single point of attachment or lug at the centre position. Therefore, attach the beam to cranes, hoist, or another lifting machine at the connection point after raising any weight. However, there are usually two or more uniformly distributed lifting lugs underneath a simple lifting beam. Therefore, these lugs sustain and connect the weight with a sling or hoisting hook.

Different brands and types of crane beams:
Crane lifting beams come in various brands, capabilities, and styles. As a result, it’s crucial to choose the proper beam to utilize with precaution. For example, you need to figure out the beam’s total efficiency as well as the capability of each particular raising point. At set or adjustable incremental, multiple and variable raising points for various sized weights should be provided by raising beams.
Crane girders are large steel I-beam sections that offer a stable track for overhead cranes to move on. Overhead cranes generally feature one to three cranes girders, depending on construction. The crane’s crab, or moving head, is equipped with a series of rollers that run on the beam’s top or bottom surface of something like the I beam. Only a crab girder is utilized in solitary girder systems. However, the crab girder is equipped with platforms at the other end and slides up and down—the unloading area on two extra crane girders when double girder or bridges cranes.
What does a crane beam look like?
During operation, crane girders, notably the crab girder, are continually exposed to a variety of load strains. All examples are the load’s vertical force, the crab’s lateral tension from accelerating or brakes, and the load’s transversal stress from swings. Crane girders are frequently strengthened by metal plates or channels throughout their mounted cross-sections to handle these loads. Crane girders must be properly graded and examined for signs of deterioration on a regular schedule to protect the safety of construction workers and the loads they transfer.
Cranes over bridges and double girders are significantly more versatile, allowing for three-dimensional hook movement. The crab may travel over the Weihua overhead crane to span the whole length of the area in these setups. Furthermore, unlike a monorail, the crane girder component may travel down the length of the room, covering a much larger area.
Crane lifting beams advantages:
Customizable lifting points on raising beams can be changed along the beam to fit a certain load. This property allows raising beams to be utilized in a wide variety of uses and to transport a wide range of loads. A lifting beam’s heavy-duty capability and strong construction are ideal for too variable weights. Do the same with materials that are delicate, such as thin steel plates or metal sheets. Therefore, the hoisting beam’s flexibility also enables it to manage to unbalance weights and regulate concave crushing pressures.
Lifting beams are appropriate for lifts with important limitations and low headroom requirements. Raising beams does not require a lot of elevation. Because they have one crane connection point. A lifting beam’s heavy-duty capability and inflexible construction are ideal for too variable weights. Do the same with metals that are brittle, such as thin metal plates or metal panels.
Before deploying a lifting beam, it’s critical to double-check your estimates. The computations’ principal goal is to model the operating values that the load will create. The load’s nature is quite important; is it strong or flexible? A flexible load necessitates a light beam, but a stronger load may require certain beam mobility.
Conclusion:
Lifting beams are frequently built for a specific application and should not be utilized for anything at all. The length of the Weihua overhead crane hook from which they have been carried will be part of this. Therefore, lifting beams should never be secured from improper hooks.
Here’s a good example of a lifting beam’s secure loaded and moving operation. The raising and manoeuvring of any weight are made faster through the use of a flexible raising beam with two elevating points and unique automated lifting hooks. At the same time, security is improved by keeping operators at a respectable distance from the load during the whole production process.
