Controlling the slew of any machine used in construction is an important part of the safety and productivity equation. This is a part of the site safety puzzle that is often overlooked by contractors and their operators but can be simply addressed with the right equipment.
Angle & Lateral Slew Limits
The Slew Control feature is a simple, cost effective slew limiting solution designed to guarantee safety and prevent machine damage when operating in confined spaces Angular slew restriction creates a V formation from the centre of the machine outwards to the maximum reach radius of the machine.
Lateral slew will require additional sensors on the arm of the machine, but will allow virtual walls to be set on either side of the machine or a combination of both. This will allow the machine to work within the safe area without the limitations that the angular V formation can give.
Setting the limit
The machine operator can quickly and easily set left and right slew limits or create a lateral virtual wall, all from the display. This will restrict the machine to working within the permitted slew sector, a very easy to use set up and it requires minimal operator training.
Reaching the limit
As the left or right slew limit is reached the “feather touch” proportional hydraulic control is released to cut off the relevant slew hydraulic service gently and safely thus stopping the machine from entering the exclusion zone.
The Slew operation in the opposite direction or back into the “safe” zone, is still permitted without any restrictions ensuring any reduction in productivity is kept to a minimum.
