Moisture and hoists what are the issues ?
Hydraulic oil is hydroscopic (likes / absorbs water), consequently exposure to water by Happ hoists voids warranty.
HAPP hoists typically only use 10L of oil in a closed system and as such a very small amount of water will cause degradation and ultimately rusting of the cylinder.
It is known that cylinders will draw water past seals if water is near the seal, and if the hoist is in a high humidity environment the hoist will draw moisture in through the breather in the cylinder. Some hydraulic oils have been supplied with water in the oil.
If you are in a high humidity area or have the hoist in an area where moisture can reach the hoist you should inspect oil quality regularly looking for any milky appearance in the oil and replace oil frequently. (always replace oil every 6-12months to counter moisture absorption).
What checks should I do before operation?
Visually check of the structure for:
Details of these inspections are logged before each use. In Australian Standards / Workplace health and safety governed premises these items are recorded in the HAPP operations control log books.
How often should I get the hoist serviced?
Every 3 months and 12 months.
In environments where Australian Standards adherence is required the hoist may also be checked for upgrades by the manufacturer for enhanced compliance or extended compliance in line with current manufacturers specifications.
These inspections are to be carried out by competent persons. In Australian Standards / Workplace health and safety governed premises these items are recorded in the HAPP operations control documents.
