SAFETY INFORMATION RT540E OPERATOR MANUAL

motion between pinch points when performing
maintenance and to avoid such areas when movement
is possible.
• Do not allow persons to stand near extending or
lowering outriggers. Foot crushing could occur
Before performing any maintenance, service or repairs on
the crane:
• The boom should be fully retracted and lowered and the
load placed on the ground.
• Do not get under a raised boom unless the boom is
blocked up safely. Always block up the boom before
doing any servicing that requires the boom to be raised.
• Stop the engine and disconnect the battery.
• Controls should be properly tagged. Never operate the
crane if it is tagged-out nor attempt to do so until it is
restored to proper operating condition and all tags have
been removed by the person(s) who installed them.
After maintenance or repairs:
• Replace all guards and covers that have been removed.
• Remove all tags, connect the battery, and perform a
function check of all operating controls.
• Consult with Manitowoc Crane Care to determine if load
testing is required after a structural repair is performed.
Lubrication
The crane must be lubricated according to the
manufacturer’s recommendations for lubrication points, time
intervals, and types. Lubricate at more frequent intervals
when working under severe conditions.
Exercise care when servicing the hydraulic system of the
crane, as pressurized hydraulic oil can cause serious injury.
The following precautions must be taken when servicing the
hydraulic system:
• Follow the manufacturer’s recommendations when
adding oil to the system. Mixing the wrong fluids could
destroy seals, causing component failure.
• Be certain all lines, components, and fittings are tight
before resuming operation.
Tires
Inspect the tires for nicks, cuts, embedded material, and
abnormal wear.
Ensure all lug nuts are properly torqued.
Ensure pneumatic tires are inflated to the proper pressure
(refer to the Load Chart). When inflating tires, use a tire
gauge, clip-on inflator, and extension hose which will permit
standing clear of the tire while inflating.
HOIST ROPE
Use only the hoist rope specified by Manitowoc as indicated
on the crane’s Capacity Chart. Substitution of an alternate
hoist rope may require the use of a different permissible line
pull and, therefore, require different reeving.
NOTE: Hoist rope may be purchased by contacting
Manitowoc Crane Care.
Wire Rope
Always make daily inspections of the wire rope, keeping in
mind that all wire rope will eventually deteriorate to a point
where it is no longer usable. Refuse to work with worn or
damaged wire rope. Wire rope shall be taken out of service
when any of the following conditions exist:
• For rotation-resistant running ropes: more than two (2)
broken wires in a length of rope equal to six (6) times the
rope diameter, or more than four (4) broken wires in a
length of rope equal to thirty (30) times the rope
diameter.
• For running ropes other than rotation resistant: six (6)
broken wires in one rope lay or three (3) broken wires in
one strand.
• One valley break where the wire fractures between
strands in a running rope is cause for removal.
• Abrasion of the rope resulting in a 5% reduction in the
original wire diameter.
WARNING
Possible equipment damage and/or
personal injury!
Driving the crane with a tire and split-rim assembly under
inflated at 80% or less of its recommended pressure can
cause the wheel and/or tire to fail. Per OSHA Standard
1910.177(f)(2), when a tire has been driven under inflated
at 80% or less of its recommended pressure, it must first
be completely deflated, removed from the axle,
disassembled, and inspected before re-inflation.
