Feed into the cut and back - motor-powered

Control panel - stationary
Log handling - hydraulic
Universal hydraulic sawmill which is, with its maximum cutting diameter of 830 mm, suitable for most lumber.
Exceptionally robust construction of the machine and high-performance hydraulic equipment allow operation even under the most difficult operating conditions including non-stop operation. Many hydraulic accessories easily handle even large logs, significantly increase the productivity of the machine and save labour costs.
The machine is equipped with a measuring system in the basic version with simple intuitive operation on a large colour touch screen. The new generation of the operating system allows a choice of four cutting modes. It is possible to set the repetition of a constant or variable thickness of lumber.
It is also possible to choose between two methods of automatic arm exit after the cut, either to a fixed height or by the last measure with an adjustable allowance.
Simple and quick entry of board thickness from an editable library.
The new system guarantees fast and accurate automatic setting of the desired cutting thickness, thus avoiding human error when setting the cut manually. It greatly saves time and makes production more precise.
The basic version is fitted with following hydraulic accessories:
- Hydraulic clamp - 2x
- Tilting angle bar - 3x
- Pull-up log turner - 1x
Thanks to the unique modular design of CTR series the machine is fitted with many fitting points for hydraulic equipment. That allows large variability of its placement with regard to the total log length and specifics of the processed material.
A wide, exceptionally massive bridge of the sawmill arm and robust running sections ensure undisturbed operation when cutting and even at high running speeds. Professional execution of all main technical units, such as running wheels with their bearing system, sawmill arm construction, powering and feeding system, etc. ensure maximum service life and machine accuracy even under the most difficult operating conditions.
The central control panel is stationary and it’s placed on the main running section. This allows convenient machine control from a single place with complete hydraulic accessories. The feed into the cut and back is driven by an electric motor with worm gearbox controlled by a frequency inverter. The travel speed can be changed simply by turning the potentiometer knob on the control panel. The end positions are secured against impact by automatic deceleration and stopping.
The massive sawmill arm is borne on adjustable hard-chromium rods (for moving up and down) which ensure absolute accuracy of sawmill arm movement and virtually unlimited service life, if the machine is lubricated regularly. The vertical movement of the arm is provided by double-sided synchronous chain transmission powered by an electric motor with worm gearbox.
The saw blade is guided in the cut by hardened and ground blade rollers. This system can be fully adjusted in all directions and it ensures the optimum position of blade rollers and the saw blade. On the guide bar additionally in combination with the hardmetal blade guiding. In order to ensure the accuracy of the cut the blade roller on the operator’s side moves as close as possible to the workpiece. Simply operated massive bearing system. It can be motor-powered and controlled as a special accessorise from the control panel (Electrically controlled guide bar).
The arm is fitted with running wheels made of high-quality grey cast iron with accurate balancing against vibrations. The wheel has a groove along its circumference. The groove holds a replaceable rubber-textile flat belt which creates an optimum contact area between the wheel and the sawblade.
The sturdily mounted running wheel is powered through a V-belts by a professional electrical motor specially balanced against vibrations. The basic version of the machine is equipped with a powerful 7.5 kW motor. For even higher performance, for example, when cutting oversized logs or even when cutting very hard materials, especially with Stellite-tipped blades an 11 or 15 kW motor can be used.
The tensioning wheel system moves along a sturdy cast iron dovetail slide with screws and a bar for fine-tuning, which allows highly accurate adjustment without any free travel even in long-term machine operation.
The basis of the machine is formed by extremely stable running sections with reversible, adjustable, steel guidance of the arm bridge. Running sections are amply dimensioned for the indicated maximum diameters of processed logs and based on practice they count even with very tough operating conditions. Double sided guidance of a bridge on the running section combined with a powerful engine, enable fluent and fast shift (removal) of cut pieces when using the Board return arms. The log length is virtually unlimited, it only depends on the number of installed running extending sections. Running sections are fitted with massive, height-adjustable log-bearing beams, tilting angle bars, and log clamps.
To increase the machine productivity is possible to install the Board return arm together with the Board slide, or the Incline belt conveyor XRB 800 which has been for space-saving purposes partially integrated into the basic machine frame. An electrically driven belt conveyor is intended for board transportation from the sawmill.
The CTR model series represents the latest trends in sawmill design, with special emphasis on maximum accuracy and long service life at minimum cost. The machines are designed in an original modular way, which allows easy replacement or adjustment of all main technical nodes and their individual parts. This significantly reduces maintenance costs in the long-term use of the machine and also reduces service times, thus reducing production downtime.
A wide range of accessories simplify and accelerate machine operation and influence its production. It is therefore possible to adapt the sawmill exactly according to the needs of the customer.
