Feed into the cut and back – motor-powered
Arm height adjustment – motor-powered
Control panel – stationary
Log handling – hydraulic
Extremely large and robust running sections fitted with massive hydraulic equipment allow handling very heavy logs of a diameter of up to 1.3 m, including the heaviest exotic tree species. Massive saw band arm is fitted with large running wheels of a diameter of 720 mm, which allows you to use saw band up to 65 mm wide. Exceptionally robust construction of the machine and high-performance hydraulic equipment allow operation even under the most difficult operating conditions including non-stop operation. Hydraulic accessories easily handle even very large logs, significantly increase the productivity of the machine and save labour costs.
The basic version is fitted with following hydraulic accessories:
Electrically controlled bar – 1x
Log Clamp – 2x
Retractable angle – 3x
Retractable Log Turner – 1x
Log Taper Adjuster – 1x
Log Taper Adjuster with Feed – 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 cutting length and specifics of the processed material. Exceptionally massive running bridge of the saw band arm and 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, saw band arm construction, powering and feeding system, etc. ensure maximum service life and machine accuracy even under the most difficult operating conditions. Continuously adjustable machine feed into the cut and back and saw band arm height adjustment. Travel speed is displayed on the digital display. 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 converter.
Bilaterally synchronously powered and guided saw band arm bridge on running sections ensures maximum stability when cutting. You can change the speed of travel simply by turning the potentiometer on the control panel. The end stops provide automatic deceleration and stopping in end positions.
The massive saw band arm is borne on adjustable hard-chromium rods (for moving up and down) which ensure absolute accuracy of saw band 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 movement controlled from the central panel has two modes of speed – rapid feed and slow feed for accurate movement to a desired position. This system can be always additionally equipped with electronic metering which automatically moves to the specified position.
The arm is fitted with large 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 belt which creates an optimum contact area between the wheel and the saw band.
The sturdily mounted running wheel is powered through a wedge belt by a professional electrical motor specially
balanced against vibrations. The machine is equipped with a powerful soft-starter that ensures smooth start-up of the main engine and reduction of impacts in the electric network.
The tensioning wheel system moves along a sturdy cast iron wedge guide with adjustable pressure bar, which allows highly accurate adjustment without any free travel even in long-term machine operation. For easier and optimum tension of the saw band the machine is equipped with hydraulic tensioning system.
Exceptionally stable running sections with double-sided adjustable steel arm bridge guides form the basis of the machine. They are sufficiently dimensioned for maximum diameters of logs as well. They were designed reflecting the practice, therefore designed to cope with very hard operating conditions. Double-sided bridge guidance on the running section in combination with a high-performance engine ensure smooth and fast withdrawal of heavy workpieces when using workpiece feeder. Cut length is virtually unlimited in all types of machines, it only depends on the length of running gear installed. Running gear sections are fitted with massive, height-adjustable log-bearing surfaces.
CTR series present the latest trends in construction of log saw bands with a special emphasis on maximum accuracy and long-term service life of the machine while ensuring minimum costs. The machines are designed in an original modular execution which allows easy replacement or adjustment of all main technical sections and their individual parts. This in the long-term perspective reduces the maintenance costs and service times and therefore production stoppages as well.
