Maintenance Introduction
A regular program of periodic preventive maintenence is essential to prolong crane
operating life, maximize efficient service and minimize downtime. This section details a
series of checks and procedures which are to be performed at daily, weekly, monthly and
semi-annual intervals. These intervals are stated both in terms of calendar periods and
hours of operation.
The checks prescribed for longer intervals include all the checks required for the shorter
intervals. Thus, the weekly check includes all items in the daily check, the monthly check
includes weekly and daily checks, and so on through the semi-annual check, which
includes the quarterly, monthly, weekly and daily checks.
A convenient check chart provides a means of recording preventive maintenance
performed and serves as a tool detecting problem areas and reanalyzing maintenance
requirements. The items in each check interval on the check chart are grouped under their
respective headings and covered in detail on pages 146 & 147.
This maintenance schedule is a guide which ensures that basic preventive maintenance
requirements will be met under average operating conditions. Conditions which impose
greater wear, loads or strain on the crane July dictate reduced check intervals. Before
altering the maintenance schedule, reevaluate crane operation and review the crane
maintenance records. Consider all factors involved and develop a revised schedule
adequate to meet routine maintenance requirements.
As a part of each periodic check, refer to the engine manufacturer’s manual for engine
maintenance requirements. When servicing the engine, the engine manufacturer’s
recommendations take precedence over those in this manual, should any discrepancy be
noted.
