ZCC1100H Crawler Crane 3-39
3.8 Checking safety measures
3.8.1 Daily inspection of the crane
The crane must be checked daily to ensure safe and good state, the items to be inspected
includes:
a) Check the daily record of work to ensure that all regular inspections, maintenance, and
repair work have been performed.
b) Check the lowering limiter, the boom angle indicator, the tilting-back supports, and other
safety devices for functional operation.
c) Check the load-bearing parts carefully, such as the wire rope (the hoisting rope, the
derricking rope, and the anchoring rods etc), the boom frame, the outriggers, and the load
hook.
d) Check if there are missing bolts, nuts, and pins, and if the components are cracked or
damaged.
e) Ensure that no modification has been made to the crane without permission, for example,
an increase or decrease in general counterweight or improper repair of boom frame.
f) Check the fuel lines and the hydraulic oil lines for leakage.
g) Check if the values shown on the instruments are correct after starting up the engine.
h) Check if the control mechanisms are working normally.
i) Check the brake and the clutch. Test the braking performance by lifting a load away from
the ground and holding it in the air for a moment.
j) Check if there lacks lubricant, grease or antifreeze fluid.
k) Check if sundries accumulate too much.
DANGER
Check the crane daily for safety and familiarize yourself with the potential dangers
brought by the work.
3.8.2 Safety checking before crane operation
The safety condition of the crane should be checked thoroughly prior to operating the crane,
including:
a) Check whether the ground provides adequate load-bearing capacity.
b) Check whether there is sufficient safety clearance to slopes and trenches.
c) Check whether the crane is adjusted to be horizontal.
d) Check whether there are live electrical wires within the working range of the crane.
e) Check whether there are obstacles which will hinder required crane operation.
CAUTION
The crane operation belongs to dangerous operation; so much attention should be
given to the working condition of the crane before and during crane operation.
For reference only.
Operators manual should be consulted and adhered to.
