30 Ton Lifting machine rough terrain crane
Brief introduction of RT30
RT30 rough terrain crane is a kind of telescopic boom and swing type crane which travels with tire type chassis. It is composed of the superstructure and undercarriage. The superstructure is the lifting part, composed of the telescopic boom, jib, main winch, aux. winch, luffing mechanism, counterweight, swivel table, etc. The undercarriage is composed of the suspension and walking part. The superstructure and the undercarriage are connected by the slewing bearing.
XJCM 30 ton rough terrain crane has safe and reliable control system,the safety device includes torque limiter,swing table lock device,winch over-winding and over-relaxation protect device,outrigger lock device outrigger bidirectional hydraulic lock,rear axle steering lock and rear wheel return detector,emergency steering power device,gradienter,hydraulic system overflow valve,balance valve.
1.Torque limiter
Detecting function:Detect the angel of the boom automatically.
Display function:Show operating information such as actual load,handing radius,boom angle
Caution Function:When the actual load exceeds rated lifting load,Torque limiter will give an alarm and stop the operation
2.Swing table lock device
During the driving process,a plug device is used to connect the swing table and the carrier to keep the steering parts(swing table,boom) from swing caused by inertia.
3.Winch over-winding protect device
When the load reaches a certain height torque limiter will stop the lifting and indicating light on the instrumentation board will be on
4.Win over-relaxation protect device
When only 3 laps of rope is left on the winch ,torques limiter will stop the falling and indicating light on the instrumentation board will be on.
