1, Engine
Cummins QSB 5.9 engine is used for Self-propelled hydraulic welding paywelder.Turbocharger as an important part of the engine, its turbine end often works at a high temperature of about 700℃, and the RPM is more than 90,000 RPM, so it must pay attention to maintenance.
2, Generator
Cummins integral alternator is adopted for the full hydraulic paywelder. The "B+" end is the voltage output end, the "L" end is connected with the charging indicator light, and the "N" end is connected with the hour meter. The full hydraulic paywelder is maintained once every 1000h. Carefully clean the slip ring to make it smooth and clean. Check the carbon brush and replace it if it is badly worn. The active parts of the shaft sleeve should be filled with lubricating oil.
3, Undercarriage
Hydraulic underpan walking part adopts hydraulic full power variable and servo control system. This makes full use of engine power and is easy to handle.
The walking part of the underpan is composed of a guide wheel, a driving wheel, a weight supporting wheel, a belt supporting wheel, a track, a walking frame, a walking motor reducer and a tightening buffer device. The walking device is the pillar of the full hydraulic paywelder, which bears all the weight of the full hydraulic paywelder and provides the walking, turning and climbing ability of the full hydraulic paywelder. The motor of the reducer is a swash plate type axial piston motor, with a high and low speed two gear shifting mechanism, which can achieve two walking speeds. The walking system of the paywelder can only be used for station transfer within the site, and the flat car should be used for transfer or long-distance movement. It is strictly prohibited for the welding vehicle to drive continuously for more than 2 hours.
PALFINGER crane,world famous brand,hydraulic driven telescopic boom,360° rotation.(Other brand are available).Beautiful appearance, strong lifting ability. The pulley at the front end of the derrick boom can swing in a certain range, and can ensure that the wire rope does not disgorge under the condition of a certain Angle, which is suitable for the rugged terrain of the site.
5, Hydraulic Pump
Sauer-danfoss hydraulic pump,straight connection with engine and generator,provides precise modulation for quick,smooth operation and superior maneuver-ability.
6, Transmission
Direct transmission mode,with simple structure,reliable performance,high transmission efficiency and maintenance tree.
