Lifting spreader beam design.
A pair of connection points on top of the beam helps to minimise the bending forces within the section and as such a semi spreader will.

We have long term employees who take pride in their work.
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.
A lifting beam is under pressure at the single lifting point and therefore subject to shear and bending while a spreader beam is designed to work under compression and spread the load out evenly over a.
