The rapid diagnosis process for common faults of forklift steering orbitrol can be summarized
as "three steps" : basic inspection, oil troubleshooting, and core testing, which helps you quickly
locate the problem and reduce downtime.
1. Basic status check (Look first, then act)
Steering wheel status: Is it abnormally heavy, stuck or completely locked when turning?
Visual inspection: Observe whether there is obvious oil leakage, oil stains or deformation at the
steering wheel housing and oil pipe joints?
Connection and linkage test: Slightly turn the steering wheel in place and observe whether the
steering wheels move synchronously? If they are not synchronized, it might be that the pull rod
is loose or the ball head is worn.
2. Inspection of oil and hydraulic systems (Check "blood" circulation)
Oil level detection: Check whether the liquid level in the storage tank is between "MIN" and
"MAX". If it is insufficient, replenish it in time.
Oil quality judgment: Observe whether the hydraulic oil is turbid, black or contains metal debris.
Deteriorated oil needs to be replaced.
Pipeline inspection: Check whether the hydraulic oil pipes have creases, aging, ruptures or loose
joints causing leakage.
Air discharge: If air enters the system, it may cause heavy steering or a "buzzing" abnormal sound.
The air in the pipeline needs to be discharged.
If the problem is not solved in the first two steps, professional-level testing is required
3. In-depth testing of core components (Precise location of fault points)
Steering orbitrol function test:
If the steering is light when empty and heavy when loaded, it might be due to insufficient pressure in
the relief valve or it being stuck by foreign objects.
If the steering wheel is empty or responds slowly, it may be due to internal wear of the steering orbitrol
such as damaged piston seals or stuck valve cores.
Mechanical component inspection:
Check whether the steering knuckle, main pin and bushing are worn due to lack of oil, causing
excessive clearance, which difficult in centering.
Check if the tire pressure is normal. Insufficient pressure will significantly increase steering resistance.
