ZREMB GH4 tube bending machine

ZREMB GH4 tube bending machine, manufactured in 1983, is used in factories during the precise processing of all varieties of installation tubes. The tube bending is performed in a semi-automatic mode on a cam with the mandrel filling the most deformed section of the tube. The machine comes with a comprehensive range of equipment shown in the accompanying photos. The GH4 mandrel bending machine weighs 2450 kg.

The ZREMB tube bending machine consists of:
– drive mechanism
– mandrel feed mechanism
– guiding mechanism
– control panel mechanism
– hydraulic system
– electrical installation assembly
– frame assembly
