· Tips for resumption of work and production ·

1. Check the cleanliness of the hydraulic oil tank fluid，Check the hydraulic oil for deterioration。

If the equipment has not been used for a long time，Impurities in the hydraulic oil settle to the bottom of the tank， Should Check and clean the dirt in the oil tank。If the hydraulic oil deteriorates，ShouldReplace with new hydraulic oil in time，So as not to cause damage to hydraulic system components.。

2. Check the oil cylinder of the whole Vehicle，Observe whether there is oil leakage during the test run、Internal leakage、Abnormal noise and other faults。

After starting the Vehicle, slowly control the cylinder to extend and retract several times.Carry out test run，Wait for the hydraulic oil to reach normal operating temperature before fully extending the cylinder，Observe for oil leakage、Abnormal phenomena such as internal leakage。

If cylinder failure is found，Timely contact the local service engineer for on-site inspection and maintenance，No“Sick”Construction。Especially in the northern alpine region.，Poor sealing of the oil seal in the cylinder may be caused by long-term low temperature storage，Causing oil leakage of hydraulic cylinder、Internal leakage，Please check carefully before resuming work and production.。

3. Check the cylinder outer surface and the piston rod for damage。

Many users place the Vehicle for a long time.，It is customary to prop up the vehicle outrigger cylinder to relieve the pressure of the vehicle tire and suspension system.，This placement is not conducive to long-term use of the cylinder.。Oil cylinder piston rod exposed for a long time，Flying stones can cause bruising on the clubface，The dirt with high salt and high alkalinity will greatly increase the probability of corrosion of the rod body.。

Before starting work， Should Check whether the piston rod is bruised in time.，Clean the dirt on the rod body。If bruise marks are found，Cylinder cannot be retracted directly，Try to grind the bruised part locally with fine oilstone until there is no hand feeling.，Retract the cylinder，If you have any questions, please contact the service engineer.。

4. Check the position of the cylinder hinge point、Joint site，Beat the butter in time，Keep lubricated。Take the wheel crane as an example.，Ball joint of outrigger cylinder、Rod head of level cylinder、Key connecting parts such as upper and lower hinge points of luffing cylinder，All neededApply butter regularlyKeep lubricated。Long-term poor lubrication may cause abnormal noise during the operation of the cylinder.、Jitter and other phenomena，In severe cases, the hinge point will be worn.、Shutdown caused by ball head fracture and other faults。

The specific characteristics and parameters shall be subject to the actual conditions.
