Accident Wrecker Use Notice
The rapid recovery of traffic on the scene of the accident depends on the professional emergency repair of the accident wrecker. Although it has always played a low-key role in the smooth passage, it is often due to emergency operations and swift action. Therefore, it is very important that the performance of the wrecker is always maintained at the best standby state. All this is based on the correct care when using it.
First, before the accident wrecker is present, it is necessary to fully understand and analyze the wrecker site and the wagons to be cleared. Select an accident wrecker that matches the model and dispatch it for repair. When driving to the scene, pay attention to the separation of the vehicle power device
Second, after the accident wrecker has gone to the scene of the accident, it is necessary to pay attention to observing the traction direction of the dragging object, and press the specified sign of the action sign to start slowly and steadily. If the to-be-cleared object needs to be hoisted, the winch clutch must not be separated when manipulating the boom, winch or other mechanical components. Suspended wire should be provided with a sufficient length of safety, the minimum standard is five times the circumference of the drum of the winch drum. It is best not to change the length and other parameters of the boom during traction, and to use a winch wire to slowly roll up the traction. Pay attention to the fact that the jib should not be overloaded so as not to cause damage to the jib and cause vehicle safety problems.
Third, if you use the lift arm drag, you should pay attention to the choice of lift position should be selected in the most stable place. At the same time try to reduce the length of the lifting arm before driving. The lift should be fastened to the fixed part of the car body with a strong strap or chain, thus avoiding the unstable factors such as bumps or brakes when dragging, causing the accident car to disengage from the bracket and causing the vehicle and the wrecker to both Different degrees of damage occurred. When driving, it is necessary to avoid sudden changes in the emergency brakes, and try to slow down and steer as much as possible.
4. If the wrecker has been cleaned up for too long, the hydraulic oil temperature should be monitored at all times. Especially when the sun is exposed to direct sunlight, the temperature of the hydraulic oil can easily rise to more than 60 degrees. During the operation, attention should be paid to lengthening the rest interval or adopting various cooling methods to keep the hydraulic oil temperature at a normal value.
The use of accident wreckers requires the operator to be familiar with more details of the operation. Only in this way can the wrecker be able to meet the speed and safety of the wrecker.
Adjustment of the Main Drive Gap of Wheeled Construction Machinery Drive Axle
1. Check and adjust the bearing clearance of the driving bevel gear. The bearing clearance of the driving bevel gear is generally 0.05-010mm. When the clearance exceeds 0.10mm, it should be adjusted: fix the dial indicator on the axle housing, and the contact of the meter is against the driving gear The outer end of the gear shaft, and then axially pry the upper flange of the gear shaft, the absolute value of the maximum and minimum readings of the dial gauge is the bearing clearance; when adjusting, you can increase or decrease the adjustment gasket between the inner ring of the driving gear bearing and the shaft shoulder. If you add a gasket, the bearing becomes loose, and vice versa.
2. Inspection and adjustment of the bearing clearance of the driven bevel gear. The normal clearance of the left and right bearings of the driven bevel gear is 0.05-0.10mm, which can be adjusted by the adjustment rings on both sides of the differential housing. First, remove the lock plate on the adjustment ring, and then twist the two adjustment rings to adjust (the two adjustment rings must be screwed in or out at the same time to ensure the meshing gap and impression of the gear pair); after adjustment, the driven gear should be It is suitable to rotate flexible and have a little resistance, but there is no loose feeling.
3. The adjustment of the thrust screw of the driven wheel loader bevel gear. For construction machinery with thrust screws on the back of the driven gear (such as ZL50 loader), the gap between the end of the thrust screw and the back of the driven gear should be 0.20-0.40mm . When adjusting, first loosen the fixing nut, then tighten the screw and back 1/3 turn, and then lock the fixing nut.
4. Inspection and adjustment of the meshing clearance and impression of the driving and driven bevel gears. Inspection methods and standards: When checking the meshing of the driving and driven bevel gears, the tooth surface of the driving bevel gear is usually coated with red lead oil first. In the case of gear meshing, turn the gear with a little resistance, and then check the traces on the Teeth of the driven gear; when meshing correctly, the contact length of the imprint should be about 2/3 of the full tooth length, and the contact traces are 2-4cm from the small end .(Main Drive,Axle Of Sdlg Loader,Pinion Ring Gear,Wheel Loader Bevel Gear)
