Ladder Operations
A ladder is provided on the left end of the cart walkboard
for material loading and routine lid/hopper maintenance.
This ladder pivots vertically, and is held in the raised
position by a spring-loaded pin. A gas piston regulates
tilting speed minimizing risk of injury during lowering.
Ladder Safety Information
Falling Hazard:
Never allow riders on the walkboard. Use only the ladder to
ascend the cart. Always face the cart when ascending or
descending the ladder. Use the hand-holds and handrails.
Make sure raised ladders are latched. A fall from the ladder or
walkboard could result in serious injury or death.
Regulatory Requirement:
Raise and latch the ladder for transport. A lowered ladder may
not meet highway clearance requirements that apply to your
operations.
Deploying Ladder

Use one hand to hold the ladder up, while pulling
horizontal pin

Using Ladder
1. Ascend and descend the ladder while facing the drill.

Raising Ladder

outside of the ladder frame.

Overhead Ladder Hazard:
Make sure horizontal pin at ladder left, near pivot, is fully
engaged when ladder is in the raised position. If the ladder is
not pinned in the raised position, it could swing down and
strike someone, or pinch a hand or arm, resulting in serious
injury. Always check the horizontal capture pin if you did not
personally set it when raising the ladder.
