INTRODUCTION NBT30H-2 SERVICE MANUAL
National Crane and our Distributor Network want to ensure
your satisfaction with our products and customer support.
Your local distributor is the best equipped and most
knowledgeable to assist you for parts, service, and warranty
issues. They have the facilities, parts, factory trained
personnel, and the information to assist you in a timely
manner. We request that you first contact them for
assistance. If you feel you need factory assistance, please
ask the distributor’s service management to coordinate the
contact on your behalf.
Service and Repair
Service and repairs to the crane must only be performed by a
qualified person. All service and repairs must be performed
in accordance with manufacturer’s recommendations, this
manual, and the Operator Manual for this machine. All
replacement parts must be approved by Manitowoc Crane
Care.
Any modification, alteration, or change to a crane which
affects its original design and is not authorized and approved
by Manitowoc Crane Care is STRICTLY PROHIBITED. Such
action invalidates all warranties and makes the owner/user
liable for any resultant accidents.
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.
• Stop the engine and disconnect the battery.
• Controls should be properly tagged-out. 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.
Recognize and avoid pinch-points while performing
maintenance. Stay clear of sheave wheels and holes in
crane booms.
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.
• Perform load tests when a structural or lifting member is
involved in a repair.

controls, augers, varying control configurations, baskets,
