Two rotatable gripper arms in the feed area secure the trunk directly in front of the saw unit and ensure it remains securely in position throughout the entire sawing process. Before sawing begins, the grapple arms are automatically closed by two hydraulic cylinders until they are firmly against the trunk and hold it securely in place. Robust ridges on the contact surfaces provide extra grip and effectively prevent the wood from twisting or slipping. Once the sawing process is complete, the double grapple opens automatically when the wood feed is activated. A diameter display that is clearly visible from the operator’s station makes it easier to select the correct segment of the MULTI splitting blade and helps to ensure that it is centred on the trunk. The grippers’ bearings can be easily lubricated from the outside via the central lubrication rail.

After the longitudinal conveyors, four conical, ball-bearing-mounted feed rollers in the machine frame ensure a reliable feed rate for the trunk to the sawing unit. The robust rollers are connected by durable chains; integrated chain tensioners perform automatic tension maintenance – without the need for manual adjustment. A powerful hydraulic motor drives the system, whilst solid bearings ensure low-wear, low-maintenance continuous operation. A trough-shaped metal panel between the rollers ensures that the trunk is perfectly centred and largely prevents debris from getting under the machine. Two integrated deflector plates ensure that any bark debris is channelled away in a controlled manner, whilst at the same time protecting the hydraulic tank and its components below from contamination. To prevent damage caused by the log feed, a built-in hydraulic valve ensures that the feed rollers are only activated once the saw blade is in its defined starting position.

The solid pressure piece, featuring an integrated double-cylinder system and a splitting force of 35, , ensures a powerful, even feed rate of the timber towards the MULTI splitting blade. The pressure plate has a non-slip surface, ensuring safety during the splitting process by holding the trunk securely in place. To ensure maximum durability and minimal wear, the pressure piece glides along the guide rail on solid brass guides. The guides can be easily maintained via an easily accessible central lubrication rail. Bolted together rather than welded – meaning that the slotted trough with guide rail can be replaced if necessary.

The automatic splitting process begins with just a single movement of the joystick. The dual-cylinder system and the Autospeed function detect how much splitting force is required and adjust the necessary splitting speed fully automatically. The twin-cylinder system ensures an even higher retraction speed for the pressure piece – saving time and boosting productivity with every splitting process. Thanks to a sophisticated mechanism, the process is controlled entirely automatically: The pressure piece feeds the trunk up to the MULTI splitting blade, splits the wood and returns automatically to its starting position – precisely, reliably and with minimal maintenance. The additional mechanical control lever allows the splitting process to be started at any time and safely stopped if necessary. The specially shaped splitting trough automatically centres the wood in the splitting channel – ensuring clean and consistent results. To ensure maximum service life, the area of the splitting trough subject to the greatest wear – at the junction with the MULTI splitting blade – is equipped with replaceable, wear-resistant steel plates. Three built-in pressure gauges in the operating area allow for continuous monitoring of the pressures in the gap system.

The following components are clearly arranged on the control panel: - Joystick for activating the splitting stroke and performing hydraulic blade adjustment, - Joystick for controlling the saw, wood rocker and feed mechanism, - Control lever for manual splitter control, - Control lever for operating the conveyor belt, manipulator and cross conveyor, - Two adjustment knobs for the pressure and speed of the saw feed, - A pushbutton for the machine’s stop function; depending on the drive type, there is an indicator light for the safety circuit, a pushbutton for starting the system, and a ball valve for switching the Autospeed function on and off. Four built-in pressure gauges for monitoring pressure conditions within the kerf system and at the saw motor.

The Autospeed function performs automatic selection of the optimum slitting speed by taking the slitting pressure into account and switching between the two feed speeds. This ensures that optimum performance is always achieved.

MULTI splitting blades are available in various combinations of the number of logs to suit different wood diameters. Depending on the type of blade, the piece of wood can thus be split into 2, 4, 6, 8, 12, 15 or 18 pieces in a single splitting process. The main cutting edge is welded continuously into the solid knife frame, ensuring a high degree of stability. The remaining cutting edges are arranged in a staggered pattern along the splitting direction, so that they do not split at the same time as the main cutting edge. The continuous vertical cutting edge performs the splitting of the piece of wood before it then comes into contact with the other side cutters. This significantly reduces the splitting force required. Between the two parts of the splitting blade, the continuous main cutting edge splits even thinner pieces of wood into two. In the 12-, 15- or 18-log models of the splitting blade, an additional ring-shaped cutting edge behind the two main cutting edges ensures that the central section of the trunk is removed and split into four parts at the same time. The logs in the outer section are split in half at the same time, resulting in smaller pieces of firewood. All main and side cutting edges are double-edged, so that the splitting process can better follow the grain of the wood, which also results in fewer splinters. The well-designed frame construction prevents the wood from becoming jammed between the knife and the machine frame. This prevents jamming and ensures that the frame blade remains height-adjustable at all times. Two plastic guides ensure that the MULTI splitting blade is guided perfectly within the machine frame. The hydraulic blade adjustment selects the appropriate blade section from the MULTI blade set, tailored to the log diameter and the number of logs. A measurement scale on each knife section, clearly visible from the operator’s station, makes it easier to centre the knife in relation to the log, thereby ensuring optimum log quality. Thanks to an integrated lifting point, the MULTI splitting blade can be replaced using a lifting tool once the fastening on the blade adjustment cylinder has been loosened.

To ensure an efficient feed rate – even with logs of longer length – a synchronously driven roller conveyor is available in addition to the four feed rollers integrated into the machine frame. This is mounted on the chassis frame and is available in a choice of different lengths. The solid, double-conical rollers (radial/axial) with serrated slats all round ensure optimum centring of the trunk and a safe feed rate into the cutting range. They are connected by durable chains – integrated chain tensioners perform automatic tension maintenance, without the need for any manual adjustment. A powerful hydraulic motor drives the system, whilst solid cast housing bearings ensure low-wear, low-maintenance continuous operation. The drive chain of the hydraulic motor can be retensioned as required and reliably maintained through regular lubrication. Solid metal plates between the rollers ensure that even shorter trunks are transported reliably – without falling through. Thanks to their lower position relative to the rollers, a smooth and even flow of logs is ensured, even with curved or irregular trunks. Wood stops fitted to the sides of the frame ensure greater safety during the conveyance and handover of trunks from the cross-conveyor system. They reliably prevent the trunks from falling sideways. The solidly built frame consists of a powder-coated, robust all-steel construction. Easily accessible central lubrication rails are provided for bearing lubrication. Lubrication can be carried out directly on the roller conveyor. An operating platform running alongside the roller conveyor provides safety and convenient access directly from the control station. Non-slip grating on the floor ensures safety and makes cleaning easy, whilst sturdy handrails provide additional protection.

From simple transport at the timber yard using a non-spring-loaded axle right through to a spring-loaded tandem chassis with EBS for safe and comfortable road transport by lorry – we offer the right solution for every requirement. For convenient loading of the firewood processor, you can optionally choose either a crane superstructure or a crane mounting kit for retrofitting.
