Lifting Beam Vs Spreader Bar

A lifting beam is a below the hook lifting device that performs the same function as a spreader.

Lifting beam vs spreader bar. At the outset it is important to clarify the difference between a spreader and a lifting beam. Arrangement of a spreader bar spreader beam vs lifting beam. A spreader beam is designed to take primarily compressive loads as can be seen in the figure above. Choose from modular adjustable and two position spreader beams and fixed and adjustable fiberglass battery lifting beams.

The main benefit of lifting beams is the substantially reduced headroom required. Tsoc offers short span standard duty basket sling universal lifting adjustable lifting four point sack four point adjustable and adjustable telescopic spreader beams for cranes. Ini adalah penggunaan jauh lebih efisien dari segi bahan dan sebagai hasilnya mengangkat balok yang pada umumnya lebih berat dan lebih mahal daripada bar spreader. The lifting beam lain dengan lifting beam balok angkat terdiri dari balok panjang yang mengubah beban angkat menjadi momen lentur melalui balok.

Lifting beams are different to spreader beams because they attach to the crane from a single central point and can have several load attachment points along their base or adjustable points as shown above. It is a simple design with one lifting eye on the beam s topside for connecting the crane. Lifting beams on the other hand consist of a long beam that converts the lifting load into a bending moment through the beam. It consists of a body and a set of lugs just like a spreader bar but lifting beams generally have one lug on the top in the center and 2 or more lugs along the bottom.

Find the load capacity minimum and maximum spread and headroom that fits your application. Lifting beams and spreader bars are some of the most common types of lifting devices however the difference is often misunderstood. Lifting beams are more appropriate for lifting large unstable objects and can be used where low headroom is an issue. Lifting beams have a single centred lifting point on the top side of the beam to connect to a crane hoist or other lifting mechanism.

While both a lifting beam and a spreader bar is similar in that they create a connection point between the load and crane there are differences that make one better than the other in specific instances. This is a much less efficient use of material and as a result lifting beams are in general heavier and more costly than spreader bars. There will be two or more lifting points on the underside of. The main difference between a lifting beam and a spreader bar is the design which dictates the way the force is transmitted during the lift.

High quality spreader beams from grainger help lift uneven loads and keep them level for increased safety. If we resolve the forces on the whole beam we get the force diagram as above.
