Product Name: WGJ-250 beam bender cold-bend arch beam bending machine WGJ-250 machine is a tunnel arch steel arch support manufacture of new equipment. WGJ-250 beam bending machine (cold-bend arch machine) is mainly used in the tunnel, subway, station, underground caverns and other I-beam, U-beam, such as bending channel angle profiles. (Performance) with hydraulic system, with smooth transmission, pressure and other characteristics. It consists of a base, mechanical transmission, cold system, hydraulic system, electrical control system and auxiliary systems, such as six major components. WGJ-250 beam bending machine works: on the beam bending machine, with reducer driven wheel after contact, will compress the feed handle lock, start the motor pump set, high pressure output from the electric pump oil through the relief valve (adjustable pressure required), enter together into the electro-hydraulic valve block with electro-hydraulic valve and jog switch (point forward, point back) control cylinders work, work to promote the fuel tank, the beam with three supporting rollers commences when pressed did not happen bending deformation, then the length of the process of advancing tanks for each 10mm-15mm, open the main motor forward or reverse, provided by the main motor power. The main technical parameters: Model WGJ-250 Specification 14-30 beam profile cylinder sliding speed 8-15mm/sec active wheel speed 7-10r/min hydraulic system powered 25mpa minimum bend radius of the total power 8.9kw Dimension 1.8 * 1.5 * 1.8m Machine weight 2380kg 1.3m Contact: Wu Jingli Mobile: 18653822725 landline :0538-8530018 QQ: 635395409 Fax 0538 -8530316
