the "-" symbol, heavier ones by turning the spring locking device
in the "+" direction.
The maximum initial tension of the balancer is achieved by X
turns of the endless screw (9) in the "+" direction:
615 805 011 0 X= aprox. 10
615 805 012 0 X= aprox. 9
615 805 013 0 X= aprox. 7
615 805 014 0 X= aprox. 6
615 805 015 0 X= aprox. 5
615 805 016 0 X= aprox. 5
A
Do not tension the spring further than this maximum initial
tension!
Adjusting the cable length
The balancer is delivered from the factory with a long cable, so
that the cable length can be individually adjusted to the onsite
circumstances. Adjusting the cable length is done with the cable
wedge (7). After lengthening or shortening the cable, the free cable
end must be compressed with the supplied ferrule (8) (or a clamp
in accordance with DIN 3093 Pts. 1 to 3); the projecting cable end
must then be cut off flush.
A
A minimum distance of 100 mm must be maintained between
the cable clamp (6) and the cable wedge (7).
Cable stop buffer / Setting the cable extension
The cable stop buffer can be moved simply by moving the flexible
cable stop buffer and the cable clamp. The cable clamp should be
secured each time.
A
WARNING: The maximum cable extension length must not be
exceeded (even with a cable extension).
Drum lock
The drum lock for this balancer (10) enables the cable drum to be
locked for changing the load or the cable without loosening the
spring. To do this, the pin with the elongated slot (10) is optionally
turned through 90° with a screwdriver to the left or right.
A
Ensure that the cable drum is securely locked. Snapping back
of the cable by unlocking the cable drum is dangerous and can
destroy the spring.
After changing the load or the cable suspend the working load and
unlock the cable drum by pressing in the fixing pin again and then
turning it to the right or left to disengage, until it springs back to
the original position.
Maintenance
Servicing / Inspection
The balancer must be serviced continuously. All external moving
parts as well as the friction points on the suspension and spring
hook must be greased. For cable care, we recommend non-corros-
ive grease because it significantly increases the cable's useful life.
The suspension, the safety chain, the spring hook and the cable
must be monitored continuously and needs to be checked by a
competent person at least once a year. If damage (such as broken
strands, "cage-type" bulging, flattened places or abrasion) is found
on the cable, or if any of the above-mentioned parts show signific-
ant signs of wear and tear, the balancer must be withdrawn from
EN
service and replaced immediately. Should the cable, spring or
other parts of the balancer need to be replaced, pre-assembled re-
placement sets are available.
Maintenance
The following sections refer exclusively to our pre-assembled re-
placement sets: cable, spring & cable drum, housing, and suspen-
sion. Be sure to use only genuine spare parts for replacement.
When replacing any of the above-mentioned components, always
follow the Operating Instructions supplied with the product.
Changing the cable
With this balancer it is possible to change the cable without releas-
ing the spring and without dismantling the device.
The "cable complete" replacement part set consists of the cable
with a pressedon clamp on the on the cable coupling, a separately
enclosed brass bush, the cable stop buffer with rubber ball and
cable clamp, plus the pre-assembled cable socket with wedge and
a ferrule (steel clamp) for pressing onto the free cable end after
adjusting the cable length, supplied loose.
Pull the cable out of the housing as far as possible. (The cable
coupling is visible in the lower part of the aperture in the housing.)
Lock the cable drum by turning the fixing pin (pin with elongated
slot on the small housing diameter) is pressed in with a screwdriver
and in this position is turned optionally right or left through 90°.
A
Ensure that the cable drum is securely locked. Snapping back
of the cable in a no-load condition by unlocking the cable drum
can lead to injuries and cause the spring to be destroyed.
Push the cable upwards out of the cable drum, remove the bush
from the cable and pull the cable downwards out of the balancer.
Introduce a new cable from below through the housing mouth
and the hole in the cable drum ("Tunnel") and push it through
upwards. Push the bush over the cable onto the ferrule. Pull the
cable in downwards into the cable drum hole ("Tunnel"). Ensure
correct coupling: the cable with the bush must be clearly and dis-
tinctly anchored in the cable drum.
Suspend the working load and set the cable drum in motion by
pulling the cable out slightly and pulling the steel pin out of the
locking device.
A
An incorrectly anchored cable can break out of the coupling
under load and cause consequential damage.
Suspend the load range and set the cable drum in motion by first
pressing in the fixing pin and then, optionally unloading by 90°,
turning it right or left, until it jumps back into the original position.
Exchanging the spring
(A) Dismantling:
Feed in the cable to the cable stop and disconnect the working
load. Then disconnect the device. Release the spring:
place a size 17 socket wrench on the endless screw. Turn the
wrench in the direction of the "-" symbol (anti-clockwise) until
the cable stop buffer is no longer up against the housing. The spring
fracture safety device is now locking the cable drum.
A
Never release the spring beyond full unload, or it will be des-
troyed.
Screw off the housing cover. Screw off the cable drum cover. If
necessary, correct the spring tension for full relief. Remove the
spring from the cable drum. To do this press the spring fracture
safety device pin fully outwards and lock it in this position with
the supplied strip.
The damaged spring is replaced with a new one. If a different
strength of spring is used, the type details and the load range on
the nameplate are to be altered accordingly.
