SURVEILLANCE OF THE PROTECTION
Visual examination can determine the integrity of the protection seals:
- absence of excessive tensions and tears.
- correct position.
- wear of the floating lip.
If necessary, replace the seal. After lubrication, remove the used greased and check for absence
of pollution like sand, brush dust, metal particles, etc…
SURVEILLANCE OF THE FIXATION
The fasteners for the turntable bearings work essentially in fatigue, it is therefore particularly
important to check that the pre charge level required for the nuts and bolts is always kept (Bolt H
M16x90 8.8 ZI).
The fasteners must be re-torqued after the first 2 to 4 months of operation, then each year
systematically.
If bolts are found loose, an expertise must be done. They cannot just be re-torqued, they must be
removed completely, then brushed and torqued again with High-strength Threadlock. Certain
regulations require replacement of all nuts and bolts every 7 years or every 14000 operating hours.
SURVEILLANCE OF THE ROTATION
During cleaning prior to greasing the teeth :
- Check carefully for the absence of foreign bodies in the teeth, turntable and sprocket.
- Check the evenness of the longitudinal range of the sprocket over the width of the turntable teeth
and correct the pin alignment if necessary.
1.2. MAST SECTIONS
1.2.1 FIXED MAST SECTION AND ITS CYLINDER
The machine is made of a mast section fixed on the chassis and of four mobile mast sections. The
assembly is a telescopic mast.
The mast cylinder is secured on the fixed mast section and the first mobile mast section. The link
between the other three is accomplished through lifting chains.
Other than lubrication of the fixed mast section, no particular maintenance is required. It is
however necessary to control the cylinder rod for the following:
- Rust.
- Scratches that would result in worn seals and leaks.
- Leaks: it is necessary to replace the seals.
1.2.2 MOBILE MAST SECTIONS
The four mobile mast sections require for only maintenance a light lubrication on the friction
surfaces between the roller ends and the mast sections without going over on the rolling surfaces.
It is important to keep clean the inside of the mast sections.
