Lifting beam vs spreader bar.
Lifting beams on the other hand consist of a long beam that converts the lifting load into a bending moment through the beam.
The main benefit of lifting beams is the substantially reduced headroom required to perform the lift.
The lifting beam lain dengan lifting beam balok angkat terdiri dari balok panjang yang mengubah beban angkat menjadi momen lentur melalui balok.
Therefore it does not require manufactured lifting beams that is lifting beams that are not custom designed to be proof tested and or marked.
It is a simple design with one lifting eye on the beam s topside for connecting the crane.
On the other hand lifting beams consist a long beam that serves the lifting load into a bending moment through the beam.
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.
Both lifting beams and spreader bars are used to spread the load of an object that needs to be lifted to make sure that the lift is done successfully without damaging the goods being lifted.
Lifting beams and spreader bars are some of the most common types of lifting devices however the difference is often misunderstood.

They re below the hook lifting devices that stabilize and support loads and both are used to keep slings perpendicular to the horizon while moving.
Lifting beams and spreader bars are similar but both have their own applications for lifting objects and are useful for different things.
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.
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.
Under the beam are two or more slugs attached to and support the load via hook or sling.
Lifting beams 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.
Lifting beams are more appropriate for lifting large unstable objects and can be used where low headroom is an issue.
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.
Spreader bars and lifting beams have quite a bit in common.
Both pieces of rigging equipment are used to transport loads with overhead lifts.
The main advantage of lifting beams is the less required space above the beam to implement the lift.
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.
