What lubricants should I use ?
What lubricants are recommended for HAPP hoists, use the following:
- Wurth HHS 2000 high pressure penetrating spray lubricant for all pulleys on cables, chains and nylon runners
- Wurth PTFE Dry lube or HHS 2000 over all exposed cables (to avoid moisture hardening of cables)
- Do not use grease or similar lubricants on the pulley / yokes on hoists as they cake and can cause damage to the pulley
- You can use grease on the nylon block sliders, with our high precision ‘P’ model hoists we can see bouncing due to the tight tolerance, in this instance the application of liberal amounts of grease on the slide points will resolve that issue. We consider this small item to be a reasonable price to pay for the most precise hoist available today.
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:
- Air and hydraulic system leaks and perishing lines.
- Loose and missing parts.
- Structural damage
- Cracks in steel or welds
- Arm locking mechanisms engaging
- Carriage locking mechanisms engaging
- Pad condition and operation
- Dyna bolt /Loxon bolt fitment
- Placards, decals, warnings, control markings and operating manuals are clear and visible
- Access and clearance provisions are adhered to
- Guarding is correctly fitted
- Concrete surrounding base is sound.
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.
