1�6 Precautions during Lubrication
and Maintenance Work
The performance of Lubrication and Maintenance
Work requires appropriate space and auxiliary
devices.
Follow the specications in the Safety Instructions
of the Operating Manual.
1. Carefully cordon off the specied area.
2. While replacing single components or large
assemblies, place them securely on auxiliary
devices and make sure that they are not subject
to any risk or damage.
3. Only use auxiliary devices that can operate
properly and have sufficient load-bearing
capacity.
4. Do not stand, walk or work under a suspended
load.
5. Only appoint experienced personnel to attach
loads and send signals to the crane operator.
The signalman must be within the crane
operator’s sight or have verbal communication
with the operator.
6. Tighten all loose screws and bolts when carrying
out the maintenance and repair work.
7. If safety devices need to be disassembled during
maintenance process, they must be reinstalled,
and immediately checked after completion of
maintenance.
8. Make sure all working materials, other
consumables and replacement parts are used in
an environment-friendly and safe manner.
9. Make sure tarpaulin and inammable materials
etc. are stored far away from places with
potential re hazards. Be careful when removing
them.
10. Check or inspect the electrical devices of the
crane regularly. Loose connections and burned
or frayed cables must be repaired or replaced
immediately.
11. Only qualied electricians or trained personnel
under supervision of qualified electrician can
perform maintenance on the electrical system
or working medium according to the electrical
technical specications.
12. Only original fuse with correct current intensity
can be used. In case of any power failure, shut
off the crane immediately.
13. Regularly check the hoses and couplings of the
hydraulic system for leakage and external
damage. Rectify or replace any damaged parts
immediately.
14. The lubrication or repair of hydraulic devices
can only be performed by staff with special
knowledge and experience in hydraulic devices
(the system must be depressurized).
15. Pressurized oil can lead to personal injury and
re.
16. Observe the safety specications related to the
product when dealing with lubricating oil,
lubricating grease and other chemicals.
17. Avoid over-lubrication which causes
unnecessary waste but also poses the following
problems:
-- Too much oil may infiltrate into the friction
surfaces and cause operation failures.
-- Lubricating oil or grease drops on the catwalks
may cause people to slip and fall.
-- Over-Full oil level may cause the lubricating oil
to bubble and cause the oil temperature to rise
too high, and result in making the oil overflow
from the tank.
-- Too much lubricating oil or grease can push out
the sealing lips of bearings when the pressure is
high.
18. Take care while dealing with thermal
consumables (scalding and burning hazard).
19. Make sure no tools are left on the equipment
after completion of the work. Falling or
unsecured tools may cause life-threatening, or
severe injuries.
20. Carry out regular inspection according to the
schedule (see part 3.4).
