What to do if my Happ 27 Lifting Systems only ascends and cannot descend?
- D
  Daniel BennettJul 28, 2025
  If your Happ Lifting Systems only ascends but cannot descend, there could be several reasons: * The bleed valve may be too tight. Try adjusting it out in ½ turn increments until the hoist descends. * There might be a connection issue in the button. Inspect the button. * The electromagnetic valve could be blocked or unopened. In this case, you should check or change the electromagnetic valve. * If it's winter, the hydraulic oil might be too dense. Add oil according to the manual's instructions.

Why does my Happ Lifting Systems engine rotate but the lift won't ascend?
- R
  Reginald SmithAug 2, 2025
  If your Happ Lifting Systems engine rotates, but the lift does not ascend, it could be due to a few reasons: * There might be dust in the electromagnetism valve. Check and clean the electromagnetism valve. * The line pole could be loose. Make sure to fix it. * It's also possible that the hydraulic oil is falling short. Refill it with hydraulic oil.

What causes shaking in Happ 27 during operation?
- A
  Ariana MendozaAug 7, 2025
  If your Happ Lifting Systems shakes during operation, it might be due to: * Air in the hydraulic pressure loop. You can release the air by redoing the ascend and descent. * An air leak at the top connect oil tube mouth of the pump. Check the seal of the oil tube mouth. * A jammed filtrate net. Clean the filtrate net.

- C
  chadrossAug 11, 2025
  If the engine of your Happ Lifting Systems doesn’t rotate, consider the following: * There might be bad contact of wires. Check or change the contacts. * If installed, the contact wires for the optional limit switch might not be bridged. Adjust or change the limited switch if installed, or bridge wires out of the motor. * There could be bad action of the limit switch (if installed). Check the electromagnetism valve and clean it.

Why is the ascend speed slow on my Happ 27?
- G
  Gina WeberAug 17, 2025
  If the ascend speed of your Happ Lifting Systems is slow, it might be due to a leaking oil seal hole. In this case, you should change the oil seal.

Hoist Assembly Steps

Assembling the hoist

Follow basic steps: place cross beams, assemble runways, place columns, attach cables.

Runway to Crossbeam Assembly

Place the cross beams on blocks

Important for easier cable installation; raise runways and move cross beams.

Assemble the runways onto the crossbeams

Lower runways, slide pulley into position; cannot lower main runway directly.

Column Placement and Attachment

Installing of slave runway

Lowering slave runway into position; install guide plates.

Place the columns onto the cross beams

Maneuver columns into position; install cables and safety mechanism.

Cable and Safety Mechanism Attachment

Attach cables and safety mechanism
