TF double drum cutter heads with direct drive for high performancePublished 5/10 at 16:08
Simex TF cutter heads are ideal for trenching, profiling rock and cement walls, tunnelling, quarrying, demolition, dredging, finishing operations and underwater works.
They are highly eﬀective where conventional excavation systems are too weak and percussion systems have little eﬀect. Their quiet operation allows them to be put to work near sensitive areas (residential zones, hospitals, schools, bridges and infrastructure).
The TF heads are especially recommended for finishing operations, where a high precision, minimum disturbance and optimum aesthetic result is required. They possess such characteristics as precise cut, low vibrations, and the ability to reuse milled material on site as well as being suitable for underwater works. Furthermore the particular shape of the frame makes it possible to reduce the distance between the drums thereby improving the total working width. Additionally the two sides of the frame have the same shape which prevents ‘chunks’ of material and stones from getting stuck between the drums and frame.
A high torque delivers high levels of performance through an integrated high displacement hydraulic piston motor, with the shafts transmitting motion only and bearing no load thanks to double support bearings for each drum. Mechanical seals on the drums prevent dust from entering, even when the attachment is submerged into the ground, even in muddy conditions. A filter on the feed line also prevents impurities from entering motor.
Milled material is discharged from the trench without getting stuck in the frame thanks to its special shape, which also allows hoses to be hooked up at sides and front. These features help ensure that the TF series delivers increased productivity and maximum precision cutting as the cutter head can be rotated 90° thanks to square holes of the coupling plate. With replaceable anti-wear plates and with drums and teeth for virtually any application, the TF double drum cutter heads have been designed to achieve higher eﬃciency based on the required application.
