A. Inspection roller, intermediate shaft and bearing; cylinder pin and bearing; boom hinge shaft and bearing lubrication and wear conditions;
B. The above parts are filled with lubricating oil. Extend bearing life.
C. Check hydraulic oil level and oil level. When the lifting platform is raised to the maximum, the hydraulic oil level should be 40-50 mm higher than the bottom of the tank. When the hydraulic oil is dark in color, the oil is sticky, or there are foreign matters such as gravel in the oil, replace the hydraulic oil in time. The lifting platform hydraulic system uses 32# hydraulic oil.
2, year-end maintenance
A. Check hydraulic and piping connections. Damage to the pipeline should be replaced immediately; tighten the fittings when the connection is loose.
B. Remove and disassemble the lowering valve, blow it clean with compressed air and reinstall it.
C. Put all the hydraulic oil in the fuel tank to open the tank, take out the oil filter, wash it, put it back into the tank, and press it to install it. The fuel tank is filled with new oil.
Layflat hoses,According to the different material, include NBR Layflat Hose, TPU Layflat Hose
According to different diameter, layflat hose include small diameter layfalt and big diameter layfalt hose
Layflat hoses were produced through-the-weave, easy cleaning and no drying required.
Designed for long service life. Tough and durable with exceptional resistance to abrasion
And cutting for use on wide variety of environment conditions.
Protected against mechanical damages.
Very low elongation (compared with vulcanized process) under pressure, prevents hose from [snaking".
High resistance to heat, fuels, chemicals, UV, ozone, weathering,hydrolysis,and microbiological attack.
Tube & cover: thermoplastic, polyurethane (TPU)
Reinforcement: High tenacity polyester filament, circular weaving.
The special extrusion through-the-weave process gives a very strong bonding between cover and lining as well as firmly encapsulation the woven polyester.
Temperature range from -50℃ to +70℃.
We can supply frac hoses with size: 8``,10``,12`` and 16``.
