Ladder General Information
The ladder on the left side of the mainframe provides
access to the walkboard for material loading and routine
lid/hopper maintenance. This ladder pivots diagonally,
and is held in position by a spring-loaded pin.
Ladder may be lowered, used and raised with wings
folded or unfolded, openers raised or lowered.
Falling Ladder Hazard:
Make sure the pin
is fully engaged when ladder is in the
raised (folded) position. If the ladder is not pinned, it could
slowly unfold during transport, striking other users of the
roadway or fixed obstructions. This could result in machine
damage, property damage, serious injury or death. The ladder
must be securely folded up for transport, and should be
securely folded for storage, to discourage climbing by
children.
Deploying Ladder
Use one hand to support the ladder, while pulling pin
to the right. Slowly swing the ladder fully down.
The gas spring provides resistance to ladder motion in
both directions. If the ladder swings freely, the spring
may be in need of replacement.
Using Ladder
Ascend and descend the ladder while facing the drill.
Use the handrails when on the higher steps.
Falling / Crushing / Overhead Hazards:
Allow no one to ride on the ladder or walkboard while the
machine is in motion. A simple fall could result in serious
injury or death. A fall in transport could result in being run
over by the cart or other vehicles. Someone standing on the
walkboard also becomes the tallest point, higher than the
transport clearance required.
Storing Ladder
The pin automatically engages the ladder during storage.
Carefully swing the ladder up, until you hear and see the
pin
seat itself with the ladder up and locked.
