Lifting beam vs spreader bar.
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 main difference between a lifting beam and a spreader bar is the design which dictates the way the force is transmitted during the lift.
Lifting beams and spreader bars are similar but both have their own applications for lifting objects and are useful for different things.
Lifting beams on the other hand consist of a long beam that converts the lifting load into a bending moment through the beam.
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 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.
A lifting beam is a below the hook lifting device that performs the same function as a spreader.
The main advantage of lifting beams is the less required space above the beam to implement the lift.
The lifting beam lain dengan lifting beam balok angkat terdiri dari balok panjang yang mengubah beban angkat menjadi momen lentur melalui balok.
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.
Under the beam are two or more slugs attached to and support the load via hook or sling.
It is a simple design with one lifting eye on the beam s topside for connecting the crane.
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.
Lifting beams are more appropriate for lifting large unstable objects and can be used where low headroom is an issue.
On the other hand lifting beams consist a long beam that serves the lifting load into a bending moment through the beam.
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.

Therefore it does not require manufactured lifting beams that is lifting beams that are not custom designed to be proof tested and or marked.
The main benefit of lifting beams is the substantially reduced headroom required to perform the lift.
Pancari dated may 15 2002 dated june 14 2002 which include.
Spreader bars and lifting beams have quite a bit in common.
Lifting beams and spreader bars are some of the most common types of lifting devices however the difference is often misunderstood.
