jakob.com ∙ [email protected]om ∙ Copyright by Jakob AG Switzerland 10 / 21
2.7 Preparation
2.7.1 Location
-Personnel must not be located on a structure hanging on the HIT-TRAC.
-When working always make sure you have a firm and safe location to stand in.
-Always stand outside the hazard area of the load to be moved, and never in the way of the exiting rope.
-You need sufficient room to move. Therefore make sure you have a sufficiently large area to stand in.
-Do not use ladders as a standing area.
-If your location is unsuitable: Install deflection roller and select a better location.
-When installing the machine take care that no external hazards can act on the rope pulling machine, the
traction rope, the load and the operator personnel. (e.g. falling objects, passing vehicles, electrical over-
head lines, and so on)
-During operation, ensure that the machine is not standing directly in water (or snow).
-
Following contact with water, you should have your HIT-TRAC checked by Jakob AG so that the brakes can be dried and
greased. If the brakes are wet, the load can either not be lowered or can only be lowered jerkily.
2.7.2 Anchoring
-Attach the machine with sufficiently strong strops or slings to the anchor bolts.
-Do not use damaged strops or lifting slings.
-In the unloaded condition, rope couplings and fixings must not come undone of their own accord.
-The machine must be able to adjust freely in the pulling direction of the rope. Otherwise there is a risk of
the housing breaking!
-When remaining in the same location for longer periods: Regularly check attachments!
2.7.3 Load
-The pulling force must not be greater than the rated pulling force of the machine.
-Secure free hanging loads against turning!
-The inherent stability of the load must be guaranteed, to prevent sliding off or tipping during the work.
-Pay attention to obstacles, which could cause the load to tip or become stuck.
-Uncontrolled loading (e.g. buckets, containers) during the lift or at interim positions is prohibited.
-When tensioning and anchoring, take into account possible stress spikes (in static condition) due to exter-
nal influences.
-Excessive impacts and loading on the pulling machine (e.g. anchoring of moving machinery, wind and so
on) must be prevented by the use of a strain relief rope.
-The efficiency of deflection devices must be considered when designing the system.

jakob.com ∙ [email protected]om ∙ Copyright by Jakob AG Switzerland 11 / 21
2.7.4 Traction rope
The condition of the rope is decisive for the reliability of the drive system.
Rope structure and inherent strength (transverse compressive strength, impact resistance) must resist the loads which occur.
-Only suitable original HABEGGER ropes must be used.
-The pulling rope must not be lubricated, and must be kept clean.
-The rope diameter must match that on the type plate.
-Damage of the rope: crushed, unwound, non-circular, kinked ropes or ropes with strand breaks or tangles
must not be used. (ISO 4309)
-Ropes with broken wires: remove carefully and correctly.
-Rope connections, sleeves, compression heads, short splices and so on must not run through the drive
system.
-When deflecting the rope over sharp edges, obstacles and so on protect the rope using suitable floor roll-
ers or supports made of wood or plastic.
-Due to unloading of the rocker, the loose robe end (2) must not hang freely for more than 50 m.
-For lengths greater than 20 m the loose rope end (2) must be rolled up properly (rollers, reels). Rope
twists, tangles, kinks etc. must be avoided!
2.7.5 Inserting rope
-Before all work, close and lock housing cover (11) above the drive system.
-When handling wire ropes wear gloves.
2.8 Working
2.8.1 Pulling and lifting
-In an emergency Release throttle lever (32/37). The driving wheel will immediately stop moving and the
built-in backstop will stop the driving wheel from turning backwards.
-The loose rope end (2) must be able to exit the pulling machine unhindered.
-Never pull hooks against the housing.
-In situations where the work cannot easily be seen: Observations by assistants, if necessary with radio
contact.
-Before starting work, check the correct direction of rotation for lifting and lowering.
-Observe the rope during the movement.
-Observe the movement of the load.
-Risk of slipping with low load!
-When pulling make sure that neither the housing nor the rope are deflected or tilted by objects or obsta-
cles.
-When pulling diagonally upwards the rope pulling machine can tilt. Place wood underneath, or avoid diag-
onal pull with rope roller.
-If the brake release lever (25) is not swivelled upwards, the load will fall at lowering speed after the throt-
tle lever (32/37) is released.
Pivot brake release lever (25) upwards immediately
-Wear ear defenders when working with the machine!

jakob.com ∙ [email protected]om ∙ Copyright by Jakob AG Switzerland 12 / 21
-During operation, the pressure roller (1), in connection with the rope geometry, can lead to elongation
slippage and accumulation of the rope so that it briefly lifts out of the V-groove of the drive sheave. The
subsequent compensation of this rope protrusion usually results in a regular, characteristic cracking or
banging noise. This phenomenon is therefore operational. The machine operation can be continued with-
out hesitation.
2.8.2 Restart under load HIT-TRAC 8B
-Allowing the coupling to slide through for too long leads to overheating and early wear and tear.
2.8.3 Lowering
-In an emergency Release throttle lever (32/37). The driving wheel will immediately stop moving and the
built-in backstop will stop the driving wheel from turning backwards.
-Risk of falling! Pay attention to loose rope end (2)! Stop lowering movement 2 m before the end of the
rope end at the latest.
-The loose rope end (2) must be able to run freely and without deformations and tangles into the machine.
2.9 Decommissioning
-The pulling rope (3) must be unloaded during decommissioning.
-Loads must be secured.
2.10 Storage and transport
-The device must be transported on pallets, secured against sliding and tilting.

3.2 Operation HIT-TRAC 8B
The machine is operated by a petrol engine using a friction clutch. If the machine is overloaded, the coupling slips through
and the load cannot be hoisted or pulled.
3.3 Operation HIT-TRAC 8A
The machine is operated by a battery motor. If the machine is overloaded, the motor stops and the load cannot be hoisted or
pulled.
3.4 Braking
The motor does not allow braking. The load is stopped using a brake which is built into the machine which needs to be re-
leased by hand for lowering.

jakob.com ∙ [email protected]om ∙ Copyright by Jakob AG Switzerland 15 / 21
4Operation
4.1 Preparation
4.1.1 Petrol motor
The STIHL petrol motor should be operated according to the STIHL operating instructions.
-Do not fill with chain lubricant
-Use the blend of fuel recommended in the STIHL operating instructions.
-Shake the fuel mixture thoroughly before refuelling. The fuel should not be older than 2 years old.
When working at high altitudes or in unfavourable climate conditions:
-Optimise carburettor settings or Reduce load accordingly.
-If being used regularly in mountainous areas, a special carburettor can partially compensate for the reduc-
tion in power.
4.1.2 Battery Motor
The STIHL Battery Motor should be operated according to the STIHL operating instructions.
-With full battery capacity must not be lowered! It has to be raised briefly before.
-Do not fill with chain lubricant.
4.1.3 Location
Suitable location for the rope puller.
4.1.4 Anchoring
The rope puller is anchored using the anchor bolt (8) with a suitable attachment on the attachment point.
The best anchor points are:
-Solid objects and constructions
-Concreted rings
-Eyelets or rods
Natural anchoring points:
-Heavy/strong boulders
-Trees
-Other suitable objects
Technical anchor points:
-Habegger field anchor with posts
-Rock anchor, concrete anchor
-Round wood anchor in ground
-These anchors depend very much on the ground conditions.

jakob.com ∙ [email protected]om ∙ Copyright by Jakob AG Switzerland 16 / 21
4.1.5 Load
The load must be determined before pulling. A suitable load dynamometer can be used for this.
Suitable means of attachment are used to fix the load on the pulling hook. These prevent the load slipping or tilting during
work. Suitable attachment equipment includes for example eyes, slings, strops, straps.
For larger rated loads:
Reduce the pulling force by using pulleys.
-The efficiency of the rope block must be included in the design of the rope system. As a rule, an efficiency
of 98% per deflection can be expected.
-Icy pulleys or stiff bearings can lead to an extreme deterioration of efficiency in the pulley block. The pul-
leys must be checked for smooth running before pulling in the rope.
-The choice of reeving can have an influence on the alignment of the rope blocks under tensile force. If
they are misaligned during operation, this can lead to an extreme deterioration of the efficiency. The
reeving must be changed in this case. The original operating instructions for the rope blocks must be con-
sidered.

4.1.6 Traction rope
Unwinding and winding up the rope must be done properly according to ISO 4309.
Matching accessories:
-HABEGGER rope reel and carrying tube
-Reel drive 4 (Art.: 00395)
-Reel drive 6 (Art. 01651)
4.1.7 Inserting rope
Only insert the rope at the end of the preparation work. This allows the rope to be pre-tensioned by hand and laid around
the drive wheel at a suitable point without an idle stroke. The rope is laid into the drive wheel according to the following
sketch or information sign (10).
1. Unlock housing cover (11) with cover handle (12) and fold up.
2. Create a loop of rope, pulling rope (3) at the bottom.
3. Swivel in pulling rope (3) at the bottom in the cable guide (4).
4. Lay loose rope end (2) at the top in the cable guide (4) and under pressure roller (1) (lift rocker).
5. Lay rope loop in rope groove of drive wheel (9).
6. Pulling rope (3) over guide roller (6) (press rocker downwards).
7. On loose rope and (2) pull the rope into the rope groove of the drive wheel (9).
8. Check correct location of rope one more time.
9. Close housing cover (11) and lock with cover handle (12).

jakob.com ∙ [email protected]om ∙ Copyright by Jakob AG Switzerland 18 / 21
4.2 Working
4.2.1 Pulling and lifting
1. Start the motor (30/35)
2. Check that the chain brake (38) is disengaged. (see arrow) To protect the
coupling, the chain brake should not be engaged for too long.
3. Set the driving wheel into motion using the throttle lever (32/37). Open the
thrttle enough that the motor runs smoothly and the centrifugal clutch grips
properly.
4. Release throttle lever. The driving wheel will immediately stop moving and
the built-in brake will stop the driving wheel from turning backwards.
4.2.2 Restart under load
1. Release chain brake (38)
2. Quickly pull the throttle lever (32/37) so that the motor can reach the required speed and the centrifugal clutch
can instantly deliver the required torque.
4.2.3 Lowering
1. Power off motor.
2. To lower the load or relieve tension in the rope, release the brake by pulling the brake release lever (25) on the
back of the machine. The chain brake (38) needs to be released for this.
3. For large enough loads (larger than approx. 100 kg), the load will move of its own accord when the brake re-
lease lever is pulled away from the housing. In this case, the centrifugal brake limits the load’s lowering speed.
The load stands still as soon as the brake lever is released.
4. If the brake release lever (25) is pivoted right down, it locks and the brake stays open!
5. For smaller loads and to release tension in the rope, i.e. when the load does not move of its own accord when
the brake is released, the crank (26) at the front of the housing must be switched to the other side, when the
brake is released, and pressed against the housing until the claw coupling clicks into place, possibly after being
rotated. By turning the crank (26) in an anticlockwise direction the load will be lowered or, respectively, the
rope tension will be relieved.
The rope speed is dependent on the speed of the hand crank.
6. After the rope tension has been relieved, pivot the brake release lever upwards again to engage the brake.
As energy produced during lowering is converted into frictional heat, the distance the load can be lowered by is restricted to
protect the lowering brake against overheating. The table provides the maximum values:
Lowering force
Lowering distance
8 kN
20 m
6 kN
25 m
4 kN
40 m
2 kN
80 m
If the load is to be lowered over longer distances, the brake should be allowed to cool (air) and then lowered the rest of the
distance.

4.3 Decommissioning
4.3.1 Taking rope out of the machine
1. Pulling rope (3) must be loose
