The way to save money is to use a smooth drum and an outer bushing
with a groove for the line, cut the bushing horizontally in two
parts and bolt or weld it to or weld it to the smooth drum. If a
different type or specification of wire rope is used in the future,
the bushing can be removed and replaced with a bushing designed for
the new wire rope. The lebus groove system ensures that the
multi-layer winding wire rope on the reel is completely smooth into
and out of the drum, and can greatly prolong the life of the wire
rope. This system is still the most effective and perfect method.
Tests have shown that the Lebus drumlcan extend the wire rope with
a rope groove matching the specifications of the wire rope.
The advantages of nylon sleeves
1. Corrosion resistance, very alkali and most salt liquid, but also
resistant to weak acid, oil, gasoline, aromatic compounds and
general solvents, aromatic compounds are inert, but not resistant
to strong acid and oxidizer. It can resist the erosion of gasoline,
oil, fat, alcohol, alkali and has good anti-aging ability. Can be
used as lubricating oil, fuel and other packaging materials.
2. Self-extinguishing, non-toxic, odorless, good weather
resistance, inert to biological erosion, good antibacterial and
mildew resistance.
3. Excellent electrical performance. Good electrical insulation,
nylon volume resistance is very high, breakdown voltage resistance
is high, in dry environment, can be used as working frequency
insulation material, even in high humidity environment still has
good electrical insulation.
4. Light weight, easy to dye, easy to shape.
Lebus sleeve Processing way
The rope groove system is formed into a sleeve with groove shape,
also known as LEBUS sleeve. After finishing, it is cut into two
pieces along the direction of 180 degrees, and finally welded with
the drum body. This method can reduce machining time and improve
machining efficiency. When the rope groove needs to be replaced for
a long time, the outer sleeve can be replaced directly, saving 500%
of the cost.
Precautions for using lebus grooves
Generally, the tighter the wire rope is, the better it is wound.
The wire rope should withstand at least 2% of the breaking load or
10% of the operating load as recommended by LeBus. Of course, for
safety factor and wire rope design, must be prepared to withstand
the destructive load.
The design and manufacture of LEBUS groove drum should meet the
special requirements of lifting operation, and the type of rope
groove should adapt to the length, diameter and structure type of
wire rope. Mechanical design, machining, design software,
mechanical engineer, equipment management, welding, hydraulic,
casting, sealing.
