Frequently Asked Questions
Have been tested in the factory lift debugging, various technical indicators have reached the design requirements, use only connected to power, hydraulic and electrical systems without adjustment. Note the use of lifts must be placed in a solid flat ground to prevent tipping work. Press the "up" or "down" button, so that working platforms. If the table does not move, stop immediately checked. Found that work pressure is too high electric lift or sound unusual, it should immediately shut down checks, to avoid severe mechanical damage; monthly check status of the Shaft of the work, such as the discovery shaft pin, screw loose, must be locked to prevent the axle pin off the accident. Hydraulic oil should be kept clean and replaced once every 6 months; lift maintenance and cleaning, be sure to hold up the safety pole.
Lift maintenance
1. Monthly maintenance
Lift maintenance personnel into the lift when the internal work must Diaozhu lift to prevent a sudden drop in lift caused casualties.
A. Check wheel, intermediate shaft and bearings; cylinder pin and bearings; arm hinge axis and bearing lubrication and wear, etc.;
B. The oil filling the parts. Extended bearing life.
C. Check hydraulic oil and the oil level. Lift up to the top surface when the hydraulic oil should be 40-50 mm above the tank bottom. Hydraulic oily discoloration dark, sticky oil, or oil in gravel and other foreign matter should be timely replacement of hydraulic oil. Application of the hydraulic system lift 32 # hydraulic oil.
2. Year-end maintenance
A. Check hydraulic and pipe joints. Pipes are damaged should be immediately replaced; joints are loose, tighten fittings.
B. Remove and open the drop valve, valve core blowing compressed air to and from the new clothes on.
C. The hydraulic oil tank in place to do all the open tank, remove the suction filter, washed back into the tank, by in situ installation. Tank filled with new oil from new.
L can not afford or weak lift up
1. Relief valve pressure regulator pressure does not meet the requirements to adjust to the required value
2. Check or replace the fuel tank vent tank components
3. Valve clamping or inspection or replacement within the vent valve assembly
4. The oil surface is too low, add enough to plug into the oil filter oil, clean filter
5. For inspection or replacement of defective pump pump
Ripper can not afford or lift up weak
1. Relief valve pressure regulator does not meet the requirements to adjust the pressure to the required value
2. The fuel tank vent see above paragraph of the exclusion method
3. Vent valve clamping or within
4. The oil surface is too low to plug into the oil filter
5. For faulty oil pump
6. One-way check valve leakage check valve and valve seat grinding damage, whether one-way valve spring fatigue, deformation
Operating rod heavy
1. Action bar mechanism faulty inspection, adjustment, replacement of failed components; cleaning valve; check the cleanliness of hydraulic oil
2. Control valve spool clamping (manufacturing, installation, dirt problem)
Faulty torque converter and compensation systems, such as the inability torque converter, power shift malfunction, oil temperature is too high
1. Inability torque converter
(1) lack of hydraulic oil
(2) pressure regulator improperly
(3) lack of back pressure check the torque converter oil quality (whether the misuse of hydraulic oil), the amount of inspection and moment regulators, back pressure valve and having a set pressure value
2. Power Shift failure
(1). Quick return valves, pressure reducing valve, power transmission valves, valve stuck there, internal leakage
(2). Oil pollution causes serious check valve stuck, and accordingly exclude, or replace hydraulic oil filter
(3). Excessive temperature rise of checking whether the faulty cooler, check the quality of the brand of hydraulic oil
