Why are there irregular slewing movements and unusual noises in HIAB Construction Equipment cranes with continuous slewing system?

  To resolve irregular slewing movements and unusual noises in HIAB Construction Equipment cranes with a continuous slewing system, first, top up the oil tank if the hydraulic system has insufficient oil. Second, ensure that the gear box has enough oil; if not, top it up to the required level. Next, lubricate the bearing while slewing. If the problem continues, the bearing assemblies or pinion might be damaged, and it's recommended to visit a HIAB service workshop.

Why is the hydraulic pump making noise in my HIAB Construction Equipment?

  If the hydraulic pump of your HIAB Construction Equipment is making noise, it could be due to several reasons. First, check if the oil tank filler breather is clogged. If it is, you will need to go to a HIAB service workshop. Second, verify that the oil level in the tank is not too low; if it is, top up the oil tank. Finally, the hydraulic pump itself might be faulty, which also requires a visit to a HIAB service workshop.

Why can't the boom system keep the load height on my HIAB X-Duo 088?

  Jennifer SmithAug 20, 2025
  If the boom system of your HIAB Construction Equipment cannot keep the load height and goes down by itself, it may be due to damaged load holding valves on the first or second boom, or internal cylinder leakage. In either case, it is recommended to visit a HIAB service workshop.

  Bruce LopezAug 25, 2025
  If the stabiliser leg cylinder of your HIAB Construction Equipment cannot keep the truck load and it goes inwards, it could be due to a damaged check valve, cylinder internal leakage, or a soft ground surface. If the ground surface is soft, set the stabiliser leg again onto the ground or add an extra support plate between the cylinder and the ground. For a damaged check valve or cylinder internal leakage, go to a HIAB service workshop.

  If one function of the HIAB Construction Equipment controller does not work, it could be because one lever of the controller was not in neutral at start up. Push in the Stop button, make sure that all levers are in neutral, and then release the Stop button.

Why do the boom extensions shake during extending/retracting on my HIAB X-Duo 088 Construction Equipment?
- D
  David HicksAug 31, 2025
  If the boom extensions of your HIAB Construction Equipment shake during extending/retracting, it could be due to cylinder internal leakage or a loose sequence screw in the cylinder head. For cylinder internal leakage, go to a HIAB service workshop. If the sequence screw in the cylinder head is loose, tighten the screw in the right position.

  If the boom extensions of your HIAB Construction Equipment cannot keep the load height and they move out by themselves, it could be due to a damaged extension load holding valve or cylinder internal leakage. In either case, it is recommended to visit a HIAB service workshop.
