NEW CONDITION DOUBLE CYLINDER AUTOMATIC WHEELSET PRESS, HYDRAULIC WHEEL PRESS FOR RAILWAY VEHICLE MANUFACTURE/MAINTENANCE

1. Product overview:

Heqiang Machinery Hydraulic Wheel Presses are used for mounting / dismounting and back pressure testing wheel-set components such as wheels, brake discs, gear, gearbox, etc. on to / off of axles for all railway rolling stocks. They are available with the following features:

• Pressing force of 2,000kN up to 5,000kN;

• Single or double end cylinders;

• Perfect centering of the wheelset during the mounting and dismounting process;

• Loading and unloading operations by means of a manually operated or fully automatic trolley;

• Automatic component positioning by means of a measuring device mechanically or laser operated;

• Mounting and dismounting of wheelset components with a single positioning on the wheel press;

• Standard roll-in or pass-through design;

• Automatic recording of mounting curve, radial and axial run-out and back pressure test of each mounted component.

2.  Main Features:

• Gantry frame structure, Dual-end cylinders, special anti-upsetting centres and movable resistant column, with delicated trolley for wheelset loading and unloading. It's suitable for assembly line.

• Fully Automatic control, CNC operating system, easy to learn, achieving the convenience and visualization of operation;
  

• High accurate measuring device, ensure that both wheel inner distance and wheel position difference can reach the relevant requirements;
  

• Multiple function of System software, including wheel calibration function, function of automatic record, intelligent judgement, print, save and query to wheel pressing curve of pressure vs displacement
  

• Unique hydraulic servo system, adjustable pressing speed, can realize the mounting, dismounting and back-pressure test requirements of various types of wheelset;
  

• Center hole positioning, pressing without turning the axle, shorten the working time and improve the process efficiency.
