Ladder Operations
Ladders are provided on the left and right ends of the
cart walkboard for material loading and routine lid/hopper
maintenance. These ladders pivots vertically, and are
held in the raised position by a spring-loaded pin.
Ladder Safety Information
Falling Hazard:
Never allow riders on the walkboard. Use only the ladders to
ascend the cart. Always face the cart when ascending or
descending the ladder. Use the handrails. If only one side of
the cart is used for access, leave the other ladder in the raised
position (as a railing). 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 ladders for transport. Lowered ladders may
not meet highway clearance requirements that apply to your
operations.
Deploying Ladder
Refer to Figure 35

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

Carefully swing ladder out and down.
Using Ladder
1. Ascend and descend the ladder while facing the drill.
2. Use the handrails when on the higher steps.
Raising Ladder
1. Swing the ladder up. The pin engages automatically,
and does not need to be held open.
2. Check that the tip of the pin is visible at the out-
side 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.
