Two companies have studied the number and type of entrapment injuries and concluded that the majority of injuries do not result from upward/ overhead impact, but from shear type impacts, caused when the operator was looking at the ground (rather than straight ahead) whilst driving. These type of injuries tend to result in a far more serious injuries.

As a result, the two companies decided that any new system should provide preventative and physical protection and allow the operator to be involved in setting the system. They also wanted it to be telematics compatible. The new system dubbed S.A.F.E (Self-Adjustment From Entrapment) includes an electronic cut out and physical barrier which can be used in conjunction with each other or individually, depending on the job and associated risks.

The electronic part is activated by the operator raising the platform to the ceiling or lowest obstacle height, holding a button on the console down for three seconds until the setting is confirmed by LED lights and a multi-tone alarm. The scissor lift will now only lift to that height until it is re-set as required. This takes care of upward movement crushing – as long as the machine is not moved to an area with lower obstacles without resetting.

The two companies then decided that a physical crash-bar type structure was needed to minimise the shear injuries caused when travelling. This has been achieved with a fold-away safety frame, based on the company’s Sanctuary Zone system for boom lifts. Ideally it should be extended before moving the lift, and can be quickly folded into the stowed position alongside the guardrails when working.
