PRELOAD CHECK.
After the crane has been readied for service, an
operational check of all crane functions (with no load
applied) should be performed. Accomplish the Preload
Check as follows:
1.
Check all pin connections, bolts, latches, locks,
braking and restricting devices and operational aids
before operation. Perform a visual inspection and
replace/tighten any damaged or loose devices prior
to initiating any craning or traveling operations.
2.
Check all braking and holding devices before
operation. Perform an operational check of all brake
(wheel and swing) and safety holding devices before
starting any crane or traveling operations.
3.
Check swing brake. Make certain the swing brake
operates correctly. Unexpected free swinging of a
boom can be dangerous.
Be sure everyone is clear of the crane and work area
before swinging boom.
4.
Raise, lower and swing the boom right and left a
minimum of 45 degrees.
5.
Telescope the boom in and out.
6.
Raise and lower the cable a few times at various
boom lengths. Ensure there is no kinking.
