- Remote control with cable 6m;
- High and constant torque;
- Self aligned welding turning roll units provide an economical and practical answer of cylindrical vessel rotating problems;
Functions:
- Forward/stop/reverse;
- Rotation speed;
- Driving vehicle forward/stop/reverse ;
- Emergency-stop;

Detail description of self aligned welding turning roll:
- Self aligned welding turning roll provides constant centerline capabilities which make set-up and alignment quick and easy.
- Self aligned welding turning rolls adjust the wheel centerline setting automatically when the vessel is lowered into place. There are no couplings to change and no pins to remove or replace.
- The self-aligned welding turning rolls can rotate work pieces with diameters as small as 850mm and as large as 5000mm without adjustment or change of drive shafts.
- Capacity is covering from 5ton to 300 ton.
- Rolls are powered with AC variable frequency drives and the motors provide motors providing a large range of rotation speeds.
- Hand-held operator pendants are standard, and optional foot switch controls are available.
- The automatically infinitely adjustable centerline settings provide easy alignment for tapered vessels, while the added surface area of 4 wheels per unit provides additional support for thin walled vessels.
- Robust design with durable rollers.
- Gritblasted steelwork with polyurethane finished coating to endure the abrasive environment of offshore and marine industries.
- Oversized bearings.
- Specially formulated high-load polyurethane tire design for high wear resistance.
- Cast steel gearbox with double worm gear arrangement for smooth operation and minimum backlash.
- Solid state inverter for precise speed control.
- Motorized and idler rail bogie versions available.
