Hydraulic Lifting Table HTH-E SILVERLINE
English
Hydraulic lines, hydraulic hoses
Minimum specifications:
High-pressure hose 2 ST DIN 20022 / EN 853 Part 2 alternatively 2 SN DIN 20022 / EN 853 Part 4
Nominal diameter DN 10; burst pressure 1320 bar
Operating pressure at nominal load
Safety instructions:
3)
The hydraulic hoses must be checked regularly and punctually for damage, they must be replaced at the
latest 6 years after manufacture or 2 years in storage after manufacture + 4 years of operating time.
If there is a hose rupture despite all precautionary measures, the part of the lifting table affected by the burst hose
is caught and retained by the line rupture protection valves. Operation must be stopped immediately if a hose
bursts. The lifting table may only be put into operation again when the hydraulic hose concerned has been
replaced.
Requirements and instructions for replacing the hydraulic hoses:
 Discharge the lifting table (with a crane or something similar)
 Engage the maintenance supports
 Replace hose (only use original high-pressure hose from the lifting table manufacturer)
mount the hose in accordance with the mounting instructions.
 Remove maintenance supports (turn down)
 Carry out a test run
Ventilating Process
The venting of the hydraulic system is a given for the test drive. This is done by multiple strokes (unloaded) of the
actuator to end position. The air from the cylinder passes through a drainage pipe in the tank and can escape
through the bleed screw again.
Recommended hydraulic oil and lubricant
For perfect function of the lifting table we recommend to use a hydraulic oil respectively a lubricant as per the
below table. These special oils fulfil best the technical requirements with regard to viscosity (walk penetration) and
pour point.
The lubricants are based on ambient temperatures of - 10° up to + 40°C.
In case of extreme temperatures, please contact us or the "Technical Services" of the below-listed mineral oil
companies.
