TRP -Heavy duty turntable positioners
The TRP series of welding table positioners cover a range of 13 different models, with capacities from 300 to 25000 Kg.
By correct positioning of weldment, using the tilt and the rotation of the table, considerable benefits can be gained in both speed and quality. The structure of heavy duty turntable positioner has been designed to support the expected loads with no vibrations or elastic deformation that could interfere with the quality of the weld. The part-holder tables are supported on preloaded ball-bearing thrust plate that ensure long-term reliability.
Rotation is provided by a motor-driven reduction unit which engages in the thrust plate toothing. The motor is supplied on c.a. with speedometer that keeps constant the rotations speed, even if eccentric loads cause a change in the torque factor.
For the models TRP 300 - TRP 1200 the tilt movement is achieved by means of electrically operated gearing in c.a.
For the models TRP 2000 - TRP 25000 the tilt movement is achieved by hydraulic cylinder with security valve and “overcenter” valve that keeps constant the tilt speed, even if eccentric loads cause a change in the tilt factor. For the electric continuity of the table a current carrying terminal is used with a self-cleaning , sliding contact (copper - broze) carrying 500A. All the electricals are housed in a relay box inside the positioner. On the door are installed all the buttons for the positioner motions and the welding process.
A remote control is also provided, with the same controls and cable length of 5 mt. Operator’s controls are stepped down to 24 V for safety.

TREV
TREV - Raisable Vertical Turning Table (for welding applications)
The movement is obtained with a hydraulic cylinder controlled by PLC mod. TREV For these types of turntable there are two versions:
- A) with the units fixed on the floor
- B) with the idle unit movable on tracks.
TRV - Vertical turning table (for welding applications)
(vertical turntable) with opposed turntable for positioning big works such as: trucks frames, coach, basements etc. The main configurations of such system may be divided into two different types:
- With fixed horizontal axis mod. TRFV
- With raisable horizontal axis.
For both types we can have the two tables (drive and idle) fixed to the ground or the idle one mobile on a trolley (empty translation).
