Cleaning Procedures
To help protect against corrosion of Grove cranes, Grove
Crane recommends washing the crane at least monthly to
remove all foreign matter. More frequent cleaning may be
needed when operating in harsh environmental conditions.
To clean the crane, follow these guidelines:
• High pressure water or steam is effective for cleaning
the crane's undercarriage and wheel housings. Keeping
these areas clean will not only help retard the effects of
corrosion, but also improve the ability to identify
potential issues before they grow into larger problems.
• Rinse dirt and dust off before washing the crane. Dirt
can scratch the crane's finish during washing/cleaning.
• Hard to clean spots caused by road tar or bugs should
be treated and cleaned after rinsing and before washing.
Do not use solvents or gasoline.
• Wash using only soaps and detergents recommended
for automotive paint finishes.
• Rinse all surfaces thoroughly to prevent streaking
caused by soap residue.
• Allow crane to dry thoroughly. You can accelerate drying
by using compressed air to remove excess water.
NOTE: Polishing and waxing (using automotive-type wax)
is recommended to maintain original paint finish.
Inspection and Repair
• Immediately following cleaning, Grove Crane
recommends an inspection to detect areas that may
have become damaged by stone chips or minor
mishaps. A minor scratch (one that has not penetrated
to the substrate surface) can be buffed with an
automotive-type scratch remover. It is recommended
that a good coat of automotive wax be applied to this
area afterwards.
• Any area scratched through to bare metal should be
touched up and repaired as soon as possible to prevent
flash rusting. To repair a major scratch (down to bare
metal) or minor damage, follow these procedures:
NOTE: Grove Crane recommends a qualified body repair
technician prepare, prime, and paint any major
scratch(es) or minor damage.
For scratches and marks in highly visible areas:
1. Sand to remove scratch. Feather outward from the mark
to blend repair into the original surface. Apply body putty
as necessary to hide the defect; then sand smooth.
2. Cover all bare metal with a primer compatible with the
original paint finish and allow to dry thoroughly.
3. Prepare surface before applying finish coat of paint.
4. Apply a finish coat using accepted blending techniques.
Use of original paint colors is recommended to ensure
the best color match possible.
For scratches and marks in areas of low visibility:
• Consider touching up the spots with a brush technique
to cover the bare metal. This will retard effects of
corrosion and enable you to do the repair later during a
normal maintenance interval.
Spots should be touched up with quality paint. Primers tend
to be porous; using a single coat of primer only will allow air
and water to penetrate the repair over time.
CAUTION
High pressure water can be forced into spaces and
infiltrate beyond seals. Avoid pressure washing near
electrical controls, panels, wiring, sensors, hydraulic
hoses and fittings, or anything that can be damaged by
high pressure cleaning/spraying.
CAUTION
To the extent any damage is structural in nature,
Manitowoc Crane Care must be contacted and consulted
as to what repairs may be required.
