OPERATING CONTROLS AND PROCEDURES CD25
3-28 Published 1-06-2017 Control # 579-01
• The boom must be lowered to horizontal and positioned
over the front of the crane.
• The swing brake and turntable lock pin must be
engaged.
• The hook block may be reeved over the main boom
nose; the overhaul ball may be reeved over the main
boom nose or auxiliary boom nose. Each must be
secured at the tie down on the carrier to prevent
swinging.
• Tires must be inflated to the recommended pressure for
pick and carry operations.
• The hydraulic tank must be filled to the specified level;
the fuel tank must be over half full.
• No loads may be supported by the boom (i.e., no pick
and carry loads) while traversing a slope.
• All cribbing or other non-standard accessories must be
removed from the crane.
• Avoid holes, rocks, extremely soft surfaces, and any
other obstacles that might subject the crane to undue
stresses and possible overturn.
• Travel must be conducted with the assistance of a
ground person to warn the operator of any changing
conditions in the terrain being traversed.
The owner/lessee must take appropriate measures to
ensure that all persons operating or working with the affected
models are in compliance with Manitowoc Crane Care’s
recommendations. The operator of the crane assumes
responsibility for determining the suitability of traveling on a
slope. Traveling on a slope should only be attempted under
the controlled conditions specified in these guidelines, and
must be conducted with the utmost diligence and care to
ensure the safety of all personnel performing the operation
and/or working around the crane.
Should the operator need to traverse slopes outside the
criteria defined in the above guidelines contact Manitowoc
Crane Care for further guidance.
Traveling with a Load (Pick and Carry)
When traveling with a load, a designated person must be
responsible for the operation. Decisions, such as the
necessity to reduce crane ratings, load position, boom
location, ground support, travel route and speed of
movement must be in accordance with that person’s
determination. Specified tire pressure must be maintained.
The boom should be carried in line with the direction of
travel. Sudden starts and stops should be avoided. Tag and
restraint lines should be used to control swinging of the load.
Elevating Personnel
Preparation and Setup
NOTE: When using the crane for lifting personnel, the
crane must be inspected daily for anything
hazardous to the person(s) being lifted.
• Be sure the platform is securely attached to the boom.
Follow the manufacturer’s instructions.
• Ensure the crane has a firm and level footing.
• Place the travel select lever in Neutral (N).
• Engage the parking brake.
• Extend and lower the outriggers.
Lifting Personnel
• Before lifting, make sure there are no overhead
obstructions or electrical wires above the platform.
• A trained crane operator must operate the controls from
the operator’s cab. Using extreme caution, lift and lower
personnel smoothly and
ONLY at their request. The
operator should always alert personnel in the platform,
and in the work area, before moving the platform up or
down.
• Always lower the platform to the travel position (boom
fully retracted and lowered) before moving the crane.
NOTE: Make sure that required restraining items, such as
railings, chains, cables, body belts with lanyards,
etc. are in place and are properly used. Never use
CAUTION
Pick and carry is not allowed when the jib is attached and
used to lift the load.
