Gen3 - User - Height Limiter & Sloping Terrain Operation

The Gen-3 safety system has the ability to limit the maximum height of the boom

This ensures the machine operates below a pre defined height limit threshold. This is useful when the machine is operating under power lines or inside a tunnel. When the Gen-3 calculates the boom has reached the height limit threshold, it will produce a hydraulic cutout - preventing the boom raise and boom extend functions of the telehandler. When the height limit is engaged, the height limit icon will be shown in the notification area.

Height Limiter on Sloping Terrain

The height limiter will adjust based on the slope of the terrain

The height limiter will take the angle of the carrier into account when performing the height limit calculation. The height limiter will assume that the height ceiling will adjust to match the slope of the terrain, so the height limit is always the same distance from the ground.

Example image below: showing two power poles on a slope.

However there may be some cases where uneven terrain such as small hills or bumps may cause the height ceiling to not always be the same distance from the ground. Under these circumstances the height limit threshold will need to be lowered to take the uneven terrain into account.

Example below showing: two power poles between a small hill

Height limit threshold will need to be lowered to take the uneven terrain into account

The height limit will only calculate the height of the boom and can not calculate the height of the attachment or the load. 

The calculated height will vary from the actual height depending on how the boom pivot is mounted to the boom. The height limit threshold will need to be adjusted accordingly.

Some machines can not support hydraulic cutouts of individual boom functions such as the raise and extend functions used in the height limiter. Before enabling the height limiter, ensure the boom raise and extend cutouts operate from the System Test Menu
