The inspection and servicing interval for the end truck is 12 calendar months for a crane in an 8-hour per
day, 5-day per week work period, under normal environmental conditions (free from excessive dust,
moisture, and corrosive fumes). The inspection and servicing intervals of the end trucks could be defined
by Safe Working Periods (SWPs) if it is being monitored. If the Safe Working Periods (SWPs) is being
monitored, then the servicing interval must always be carried out at the end of the Safe Working Period
(SWP%) of the crane or hoist, or by the end of the stated number of calendar months, whichever comes
first. If the end trucks are being used intermittently, they should be inspected before being used again.

If the duty is heavier, or the environment severe, service intervals should be shortened and more
frequent.
