him to use it to the full extent of its intended
capabilities. The operating
contain important information on how to
handle the product in a safe, correct and
economic way. Acting in accordance with
these instructions, helps to avoid accidents,
reduce repair costs and downtime and to
increase the reliability and lifetime of the
product. The operating instructions and the
accident prevention act is valid for the
respective country and area where the
product is used. And also the commonly
accepted regulations for
professional work must be adhered too.
The user is responsible for the proper and
professional instruction of the operating
personnel.
CORRECT OPERATION
• This product has been designed to handle
loads, which are constantly lifted.
- The capacity indicated on the unit is the
maximum safe working load ( W L L) that
may be attached.
- Do not allow personnel to pass under a
suspended load.
- Start moving the load only after it has been
attached correctly and all personnel is clear
of the danger zone.
- The operator must ensure that the load is
attached in a manner that does not expose
himself or other personnel to danger by the
product or the load.
- The product can be operated in ambient
temperatures between - 10° C and + 50° C.
Consult the manufacturer in case of
extreme working conditions.
- Prior to operation of the product in special
atmospheres (high humidity, salty, caustic,
alkaline) or handling hazardous goods (e.g.
molten compounds, radioactive materials)
consult the manufacturer for advice.
- If defects are found, stop using the spring
balancer.
• For use in the food-industry, consult the
manufacturer.
- When using spot-welding guns, take care
that the unit is insulated because of the
current leakage.
- The suspension (trolleys etc.) should be
mounted so that the
perpendicular.
INCORRECT OPERATION
- Do not exceed the rated capacity of the
spring balancer.
- Welding on hook and wire rope is strictly
forbidden.
- The wire rope must never be used as a
ground connection during welding (Fig. 1).
• Side pull, i.e. lateral load on either housing
or bottom block is not permitted (Fig. 2).
- Do not use the spring balancer for
transportation of people (Fig. 3).
- Do not remove the safety latch from the
hooks (Fig. 4).
- The load must always be seated in the
operating
saddle of the hook. Never attach the load to
the tip of the load hook (Fig. 5). This also
applies to the suspension hook.
- Do not knot or shorten the wire rope by
using clamps, screws, screwdrivers or other
instructions
devices (Fig. 6). Do not use the wire rope
over sharp edges.
- Do not throw the spring-balancer down.
Always place it carefully on the ground.
- The unit must not be operated in potentially
explosive atmospheres.
INSPECTION BEFORE INITIAL
OPERATION
Each balancer must be inspected prior to
initial operation by a competent person.
safe and
The inspection is visual and functional and
shall establish that the unit is safe and has
not been damaged by incorrect transport or
storage. Inspections should be made by a
representative of the manufacturer or the
supplier although the user company can
assign its own suitable trained personnel.
INSPECTION BEFORE STARTING WORK
Before starting work, inspect the spring
balancer, the wire rope and all load bearing
constructions for visual defects every time.
Furthermore, test, that the load is correctly
attached by carrying out a short work cycle of
lifting/pulling, tensioning and releasing.
Inspection of top suspensions
(Trolleys etc.)
The suspensions, like trolleys, have to be
inspected for any wear or damage.
Inspection of top and bottom hooks
Inspect
deformations, damage, cracks, wear or
corrosion marks according to DIN 15405-1.
Inspection of the housing
Inspect
damage, cracks, wear or corrosion marks.
Inspection of wire-rope guide
Inspect the wire-rope guide for any wear or
damage.
Inspection of wire-rope
For safety reasons, the wire rope must be
changed if the amount of wire breakage is
higher than the presented regulations for the
load is kept
relevant country of use.
The breakages must be counted along a wire
rope length of 6 resp. 30 times of the wire
rope diameter (see Tab. 1).
The wire rope has to be changed if a
complete cord is broken, there is waviness,
links or other wear and damage. Guidance for
inspection and maintenance of wire ropes are
DIN 15020-2 „Grundsätze für Seiltriebe,
Überwachung und Gebrauch" and ISO 4309
„Cranes - Wire ropes - Care, maintenance,
installation, examination and discard" also in
top and bottom hooks
the housing for deformations,
corporation with the regulation of the country
of operation.
The wire rope has to be replaced:
• If the number of visible wire breakages is
higher than a mandatory amount.
• If a complete cord is broken.
• If the wire rope shows bulges, kinks,
pinches, consistent deformations, buckling,
or any other indication of excessive wear.
• If the wire rope is damaged by any kind of
heat influence.
• If the wire rope shows corrosion inside or
outside.
• If the wire rope is extremely worn due to
insufficient lubrication.

INSTALLATION

- According to DIN 15112, a secondary
support cable or chain has to be fitted (Fig.
6, Pos. 2). Attach one end of the secondary
support cable or chain to the balancer body
and the other end to a separate fitting
which does not support the balancer. Leave
some slack in the secondary support cable
or chain to allow the balancer to rotate
freely. The slack must be a suitable length
so that the balancer will stop within 100 mm
of the suspension point in case of failure of
the suspension hook or the fitting (Fig. 7).
- Attach the suspension hook of the balancer
directly to a suitable fitting. Check the
safety latch is closed. Take care that the
balancer does not hit surrounding objects.
- Ensure that the top hook can swivel freely.
ADJUSTMENT OF SPRING TENSION
Note! Before attaching, check if the total
load, including all accessories, is within the
capacity range of the balancer.
- After attaching the load, adjust the spring
tension. To adjust the spring tension, turn
the worm on the rear side of the balancer
(Fig. 6/Fig. 8) with a wrench etc. Turn
for clockwise for increasing the spring tension,
turn counter-clockwise for reducing the
spring-tension. The gauge on the front side
(see Fig. 6/Fig. 9) shows the approximate
springtension.
Attention! Over adjustment could cause
damages to the balancer body, the wire-rope
and also to the spring-assembly.
- To remove the attached load from the
bottom hook, pull out the wire rope (34)
completely and lock the drum with the
manual-drum-lock.
- Pull the stopper (11) and turn it clockwise
(30°) to place it in the lower slot at the
lockposition (Fig. 6/Fig. 8).
Attention! Move the suspended load upward
and downward until the stopper enters the
slot in the pulley and the pulley becomes
locked. Move the load again to check the
drum is locked securely.
SPRING REPLACEMENT
DISASSEMBLY (see Fig. 10)
Attention! Never remove the spring from the
spring case. If removed, the spring will
expand explosively and cause personal
injury. Replace the spring assembly only as a
complete unit.
