Gearbox experts
At Tractive we are transmission experts and know how to design a multi step gearbox which lasts and last, for thousands of hours.
A multi step gearbox offers unparalleled torque characteristics of the saw head. Independent of what size blade is needed, the 2-speed respectively 4-speed gearbox allows the Pentruder wall saw to work with a remarkably high torque at all spindle speeds.
With high cycle inverter technology the frequency can be altered infinitely. This is how most of our competition alter the spindle speed.
Power is proportional to speed
BUT, with lower speed of the motor, power is lost. If the torque is kept constant, power is proportional to RPM and even if torque is constant, the power output is halved if RPM is halved. |
