Choose from modular adjustable and two position spreader beams and fixed and adjustable fiberglass battery lifting beams.
Lifting beam vs spreader bar.
Under the beam are two or more slugs attached to and support the load via hook or sling.
If we resolve the forces on the whole beam we get the force diagram as above.
A spreader beam is designed to take primarily compressive loads as can be seen in the figure above.
Lifting beams are more appropriate for lifting large unstable objects and can be used where low headroom is an issue.
At the outset it is important to clarify the difference between a spreader and a lifting beam.
A lifting beam is a below the hook lifting device that performs the same function as a spreader.
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.
High quality spreader beams from grainger help lift uneven loads and keep them level for increased safety.
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.
It is a simple design with one lifting eye on the beam s topside for connecting the crane.
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.
On the other hand lifting beams consist a long beam that serves the lifting load into a bending moment through the beam.
There will be two or more lifting points on the underside of.
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.
Lifting spreader bar and adjustable beam lifts our lifting spreader beams and bars allow you to turn a crane hook into a multiple point lifting tool.
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.
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.
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.
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.
Arrangement of a spreader bar spreader beam vs lifting beam.
Find the load capacity minimum and maximum spread and headroom that fits your application.
