Tilting saw conveyor PTO

Cutting firewood at its best

The HMG tilting circular saw with 4m or 5m telescopic conveyor belt of the WSK 7F series is available with a power take-off shaft connection or combined with an electric motor and is driven by a V-belt system. The drive is geared so that energy-saving firewood cutting is achieved at a low PTO shaft speed. The V-belts protect the drive systems and increase work safety. Thanks to the welded square steel tube frame, it achieves the highest level of stability. The cutting protection device can be opened wide for convenient operation. The system protected by a utility model (DE 20 2020 100 105.1) also has a very large opening of the rocker, which enables light wood fitting. The rocker is designed ergonomically and smoothly and is easy to operate thanks to integrated tension springs. The conveyor belt is driven by its own oil supply via a hydraulic pump. The conveyor belt is extended from its compact transport position to the working position with maintenance-friendly hand winches and adjusted to the desired ejection height. The conveyor belt consists of special nubbed textile segments, which ensure that the conveyed goods are transported away more quickly. The conveyor belt speed can be set from 0-91 cm / sec via an adjustable valve. Another special advantage lies in the construction of the wood feed shaft, because the piece of leftover wood that no longer needs to be cut and remains in the rocker does not have to be thrown into the feed device by hand, but can simply be pushed through with the next log to be cut . Subsequent retrofitting of structural components is possible at any time (e.g. electric motor for PTO drive).

  • Only a low PTO speed of 270 rpm is required
  • Conveyor belt is driven by its own oil supply
  • Conveyor belt speed adjustable from 0-91 cm/sec
  • More work safety through V-belt drive
  • Large opening of the feeding device (rocker)
  • Three-point suspension for CAT I and II as standard
  • High cutting depth of 28 cm thanks to a large saw blade with a diameter of 70 cm (30 mm hole)
  • Wide rocker with internal galvanized rocker plate
  • Smooth rocker thanks to strong tension springs and shock absorbers
  • Individually adjustable rocker handle
  • Stop firmly mounted with screws, no slipping possible
  • Removable chip ejection grid for quick removal of wood and bark residues
  • Compact transport position, only 1.65 m wide

Additionally with combined drive with electric motor:

  • Powerful electric motor in a stable cast iron housing with reinforced base
  • Switch-plug combination with reinforced brake electronics, motor protection and phase inverter
  • A robust square steel tube construction ensures maximum stability. The welded frame is torsion-resistant and withstands the large cutting loads better than a sheet metal construction. A high-quality powder coating protects against rust.
  • The cutting protection device can be opened wide for convenient operation. The system protected by a utility model (DE 20 2020 100 105.1) also has a very large opening for the wooden support device (rocker), which enables light wood assembly.
  • A circular saw driven by a V-belt has a better cutting performance, because the built-in transmission results in a higher saw blade speed. Energy-saving firewood cutting is possible with the PTO shaft only running at 270 rpm. In addition, work safety is increased if the V-belts can slip when blocked. The V-belt shaft is equipped with two self-lubricating industrial ball bearings and has a long bearing, which withstands the loads better than a short shaft. The V-belts are arranged on the outside, so a quick V-belt change can be carried out and the saw shaft does not have to be laboriously dismantled.
  • The PTO drive can be switched off immediately in the event of a fault and the saw blade comes to a standstill within 10 seconds.
  • The rocker is designed ergonomically and smoothly and is easy to operate thanks to integrated tension springs. Galvanized exchangeable sheets protect the support device from wear.
  • The saw blade protection hood can be swiveled backwards in just a few simple steps, thus enabling the saw blade to be changed very quickly without having to laboriously dismantle the circular saw. The tool for changing the saw blade is securely attached to the machine for transport.
  • To determine the desired section length (25cm, 33cm, 50cm), the stop is firmly fixed with 2 screws and can therefore not be accidentally adjusted during the sawing operation.
  • With only 270 rpm of the PTO shaft, the circular saw can be used to cut energy-saving firewood. At 350 rpm on the PTO shaft, the saw blade runs around 1700 rpm and would be ideal for processing firewood faster.
  • The conveyor belt is driven by its own oil supply via a hydraulic pump.
  • The conveyor belt speed can be regulated continuously from 0-91 cm / sec. This allows the ejection distance of the cut pieces of wood to be influenced.
  • An extension that can be pulled out up to 50cm is ideal so that the cut wood does not fall on the floor and at the same time serves to determine the desired section length.
  • The compact design makes it easy to transport. In the transport position, the machine is only 1.65 m wide, 2.55 m high (can be shortened by swiveling the conveyor belt!) And 1.40 m deep.

* Bestseller

In its 5/2020 issue, the magazine “Heimwerker Praxis” rated an HMG WE 7-8 tilting circular saw as “upper class” and with a grade of 1.4. An excerpt from the assessment: “… a great machine with a very high safety factor that makes making firewood a fun factor. Every euro is well spent here …”
HMG machines are designed and manufactured according to principles valid machine guidelines. each machine a functional check is subjected to prior to delivery.

Boaters are to be audited, so HMG circular saws by the laboratory are checked. A valid type certificate is in any manual of the machine!
