If a boom truck is set up on outriggers without a front stabilizer, what is the working area typically limited to?

When a boom truck is set up on outriggers without a front stabilizer, the working area is typically limited to 180°. This limitation occurs because the absence of a front stabilizer compromises the stability and lifting capability of the crane, particularly when operating in the forward direction. The outriggers provide lateral stability, but without the front stabilizer, the operator must be cautious about extending the boom far forward or to the side, as this increases the risk of tipping the crane.

Typically, with full stabilization, a crane can potentially operate over a 360° range. However, when lacking a front stabilizer, the safe operational area is reduced significantly. Limiting operations to 180° ensures that the crane remains stable and that the risk of failure is minimized, allowing for safer maneuvering and lifting of loads without endangering the crew or equipment.
