Lifting beam vs spreader bar.
Lifting beams and spreader bars are similar but both have their own applications for lifting objects and are useful for different things.
A lifting beam is a below the hook lifting device that performs the same function as a spreader.
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 more appropriate for lifting large unstable objects and can be used where low headroom is an issue.
Pancari dated may 15 2002 dated june 14 2002 which include.
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.
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.
Under the beam are two or more slugs attached to and support the load via hook or sling.
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.
Both pieces of rigging equipment are used to transport loads with overhead lifts.
It is a simple design with one lifting eye on the beam s topside for connecting the crane.
Lifting beams and spreader bars are some of the most common types of lifting devices however the difference is often misunderstood.
The main benefit of lifting beams is the substantially reduced headroom required to perform the lift.
Therefore it does not require manufactured lifting beams that is lifting beams that are not custom designed to be proof tested and or marked.
Lifting beams on the other hand consist of a long beam that converts 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.
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.
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.

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.
The lifting beam lain dengan lifting beam balok angkat terdiri dari balok panjang yang mengubah beban angkat menjadi momen lentur melalui balok.
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.
