The alignment of the rope drum in the direction of pull enables easy rope pull-out and low rope wear, since the rope is not spooled and wound over several rope pulleys in different directions. According to the KWF test, Pfanzelt geared cable winches have the lowest power requirement when pulling out. In addition, the winch is attached to the tractor with a particularly favorable center of gravity.

 

Blade

Pfanzelt S-line geared cable winches have a particularly stable shield made of high-strength fine-grain steel, which is manufactured as a torsion-resistant torsion box. Due to the wedge shape, lateral tensile forces can also be absorbed safely, stably and durably. Parking supports that can be operated from the side ensure that the cable winch can be conveniently attached and removed from the tractor and prevents accidents.

Pfanzelt winch transmission S172, S160, S150The winch is driven by the tractor PTO at a speed of 540, 750 or 1000 rpm. The drive power is transmitted from the cardan shaft to the precision worm gear in an oil bath via a spur gear. This ensures very smooth operation and long-term operational reliability.

Multi-disc sintered plate packs are used for the exact control of the braking and clutch processes and the safe overlap. The complete system is installed inside and protected.

Lowest loss of traction S172, S160, S150The use of a rope drum with a large drum core diameter guarantees a very low loss of tensile force from the lower to the upper rope layer. According to an independent test by the KWF, the S-line cable winch has a maximum drop in pulling force of 21% for the standard cable length. The low cable entry height enables easy and comfortable work without a pulley.

Pfanzelt PPS controller S172, S160, S150With the Pfanzelt PPS precision control, which is unique on the market, the cable winch can be adapted to the respective skidding situation. The operator can quickly and easily adjust the overlap between clutch and brake by preselecting. This offers maximum ease of use and maximum safety at work.

Cable distribution, S172, S160, S150Always a tight rope when pulling in, even if the trunk slips or the rope is pulled up loosely – this is made possible by the Pfanzelt rope inlet brake. A cylinder presses the rope onto the brake block when it is pulled in with a brake roller. The force of the cylinder is so dimensioned that the rope is only pressed onto the block when it is not under load. When pulling out the brake opens completely.

The spring-loaded pressure roller is recommended for long rope lengths. This also helps to distribute the rope optimally over the entire width of the rope drum. If you choose the option of cable distribution including an infeed brake, this is part of the standard equipment.

Pfanzelt Rope ejection  S172, S160, S150The Pfanzelt rope outlet was developed to increase the ease of use. The unwinding device built into the swivel arm of the cable distribution is mechanically driven and hydraulically switched. The rope is pressed firmly to the rope pulley over a large radius via several flexibly suspended pressure rollers. Due to the large contact area, functionality is ensured despite contamination or rope damage.

If a tensioned rope is loosened, this often creates a mess on the drum. The new PTB drum overrun brake automatically brakes the drum in such cases, thus ensuring that the rope is properly wound. An easy and unproblematic pulling out of the rope is guaranteed. 

Pfanzelt load lowering valve  S172, S160, S150Pfanzelt S-line geared cable winches can be equipped with a load lowering valve. This enables a tensioned rope to be relieved and lowered in a controlled manner. This is essential in the case of security breaches. To avoid malfunctions, the cable winch works with a separate oil circuit with a filter unit, which is fed by a piston pump and controls all hydraulic functions.

Storage spaceSpecially adapted holders for chainsaws and fuel canisters and, depending on the model, two additional storage compartments ensure sufficient storage space for work in the forest.

Pfanzelt standard radio control

The S-line cable winches are equipped with radio control for safe, comfortable and stock-friendly work. The operator is not in the danger zone and can recognize obstacles.

The security
update The new radio control decouples pulling and releasing. The drag command is now activated via a pushbutton.

All functions at a glance

  • Drag (via pushbutton)
  • Release, short release (via rocker arm)
  • stepless motor speed adjustment
  • Emergency stop switch
  • PPS NEW switchover via radio

Active operator protectionThe TUTUM anti-crushing protection prevents hand crushing and injuries from rope damage. This protective mechanism is only
standard at Pfanzelt.

Front mountingInstead of the standard spur gear, this can optionally also be supplied as a spur gear with a second PTO stub with reversal of the direction of rotation for attaching the cable winch in the front.
