Maintenance guide

1. General instructions

Bring to avoid pollution of hydraulic oil, please clean the funnel before to the hydraulic tank refueling and refueling, prevent dust and sand in the fuel tank. Oil of the highest oil level line should not be higher than that of fuel tank oil level gauge, in order to avoid the hydraulic oil overflow.

For a new car after lifting 300 times please change in time or hydraulic oil filter.

For all should be lubricated regularly rotating point reduce wear to extend the service life.

I regularly check whether the oil cylinder, the bolt support have loose phenomenon.

For amplification should be inspected regularly fixed on the function of parts loosening, slide.

Tip:

Near or in the rotating parts for maintenance is dangerous.

Maintenance for lift car, please ensure the car got security support.

Didn't get the security support in train or car work below will be life-threatening.

2. The hydraulic oil is chosen

Bring about damage to avoid the hydraulic oil cylinder, we suggest that the hydraulic oil viscosity (40 DHS С) should be in between 75-16 was/s. Top oil temperature does not exceed 80 DHS С.

For when the environment temperature for - 10 DHS С - 40 DHS С region, the proposal chooses L - HM anti-wear hydraulic oil, summer USES the 46 #, 32 # in winter.

For when the environment temperature in summer is 40 DHS С region, the proposal chooses L - HM68 anti-wear hydraulic oil.

For when the environment temperature for 30 DHS С region, the proposal chooses L - HV32 low-temperature hydraulic oil.

For when the environment temperature for 30 DHS С area, under the proposal chooses L - HS32 hydraulic oil at low temperature.

Tip:

When the oil temperature in 65 DHS С above, please use the hydraulic oil cooler, avoid the hydraulic oil overheating.

Low temperature hydraulic oil can not be used mixed.

3. Maintenance and maintenance

Bring in order to save maintenance costs, reduce downtime and prolong the service life of hydraulic products, daily visual inspection is necessary.

Need daily check parts are:

1. Empty lift check whether oil cylinder, enlarge to the deviation on both sides.

2. Check the oil level of hydraulic oil, observe the car, if there is a car under hydraulic oil drip, observe whether the hydraulic oil cylinder has ooze, oil leakage.

3. Gross appearance check cylinder, amplification, with the upper and lower bearings and rotating point and installations.

4. Check the oil cylinder bearing and former DingGang at the top of the nut is loose, oil cylinder bearing clearance is reasonable.

5. Check the oil cylinder, amplification, bearing lubrication situation of each pivot point up and down in a timely manner to fill lubricant.

6. Check the rotation point of composite bushing wear, be replaced in a timely manner.

Tip:

Dumping mechanism to the deflection is very dangerous.

Oil cylinder on the upper and lower bearings fastening bolt looseness is dangerous and could lead to dumping mechanism seriously damaged and even overturn.

Everyday

Once a week

Every three months

Every half a year

Oil cylinder

All the parts

Check the oil cylinder lubrication and wear condition, to check whether there is pressed into, return pipe is blocked, check whether the DingGang cover before the top fastening nut is loose, check the oil cylinder work, damage and leakage situation

Clean the oil cylinder surface, make butter to each activity shaft head

Once the hydraulic oil filter replacement

Completely replace the hydraulic oil

Tilting mechanism

  Amplification, upper and lower bearings

Check the amplification, upper and lower bearing lubrication, wear, deformation, check whether the fastening bolts is loose

Clean amplification appearance, make butter to each activity shaft head

Replacement of a composite liner

 

Tip:

Shall not use any steam cleaner to clean the hydraulic products (cylinder, high and low pressure oil pipe and other hydraulic components)
