Commercial vehicles that depend on hydraulics can quickly become unproductive when a hose, cylinder, pump, valve or auxiliary hydraulic system fails.
Completely Hydraulic provides mobile and workshop hydraulic support for commercial fleets, including HGVs, tippers, grab vehicles, compactors, loader cranes, tail lifts and other hydraulically operated vehicle equipment.
Support ranges from urgent breakdown repairs through to planned hydraulic maintenance and workshop engineering.
Fleet hydraulic support covers the hoses, cylinders, valves, pumps and auxiliary hydraulic equipment used on commercial vehicles. CH can attend many faults on site and route more complex cylinder, pump or component repairs through its hydraulic workshops.
Fleet hydraulic support is the maintenance and repair of hydraulic equipment fitted to commercial vehicles and mobile machinery.
Depending on the fleet, hydraulics may operate:
The objective is not simply to repair the individual component, but to understand how it works within the complete vehicle hydraulic system.
CH can support fleet operators with hydraulic work including:
Jump the queue. Reduce downtime. Pay less for parts, labour and callouts.
✔ Priority response
✔ Lower rates day & night
✔ Trade discounts on parts
✔ 30-day credit terms (approved accounts)
Hydraulics are used throughout transport, construction, waste, logistics and municipal fleets.
| Vehicle / Equipment | Typical Hydraulic Functions |
|---|---|
| Tippers | Tipping cylinders, pumps, PTO systems, hoses and control valves. |
| Grab lorries | Boom cylinders, stabilisers, grab controls, hoses and valve systems. |
| Loader cranes | Boom, extension and stabiliser hydraulics, control valves and pipework. |
| Waste vehicles | Compactors, bin lifts, cylinders, hoses, valves and pumps. |
| Hook & skip loaders | Main lifting cylinders, stabilising systems and hydraulic controls. |
| Tail-lift vehicles | Cylinders, hoses, power packs and associated control systems. |
| Vehicle-mounted access equipment | Boom and platform movement, stabilisers and hydraulic power systems. |
Hydraulic hose failure is one of the faults that can often be dealt with directly at a vehicle depot, work site or breakdown location.
A mobile engineer can assess:
The damaged pressure hose should normally be replaced as a complete correctly specified assembly.
If the same hose repeatedly fails on a fleet vehicle, replacing it again without investigating routing, abrasion, heat, twisting or machine movement can simply reproduce the fault.
See 24/7 Site Mobile Hydraulic Service.
Hydraulic cylinders carry out much of the heavy work on fleet equipment.
They can be found on:
Possible cylinder problems include:
Many cylinders can be repaired or refurbished. Others may be better suited to replacement or custom manufacture.
See Hydraulic Ram Repair.
Replacement may become appropriate where a cylinder is:
The replacement should match the hydraulic and mechanical requirements of the vehicle rather than simply having similar external dimensions.
See Hydraulic Ram Replacement UK.
Many commercial vehicle hydraulic systems receive power through a PTO-driven hydraulic pump arrangement.
If an auxiliary hydraulic system becomes slow, noisy, weak or stops working, possible causes can include:
The pump should not automatically be replaced simply because the hydraulic equipment has lost performance.
Slow or weak vehicle hydraulics can have several possible causes. Checking the complete circuit can prevent a serviceable pump, valve or cylinder from being replaced unnecessarily.
See Hydraulic System Troubleshooting & Diagnostics.
Valve systems control the direction, pressure and flow of hydraulic oil throughout commercial vehicle equipment.
Potential symptoms include:
However, similar symptoms can also result from cylinders, pumps, control systems or other parts of the hydraulic circuit.
A hydraulic leak should be investigated rather than repeatedly topping up the reservoir.
Leaks can occur at:
High-pressure leaks should never be searched for by hand because hydraulic fluid can penetrate the skin.
See Hydraulic Leak Detection & Repair.
It depends on which hydraulic circuit is affected.
A hydraulic leak involving steering, braking, stability, load control or another safety-critical system should be treated differently from a fault confined to an auxiliary circuit.
Even where an auxiliary circuit is involved, the affected equipment should not continue operating until the fault has been assessed.
See Can You Drive With a Hydraulic Leak?.
Planned maintenance can help identify deterioration before it develops into an unexpected breakdown.
Useful fleet hydraulic checks can include:
The frequency and scope should reflect:
See Hydraulic Preventative Maintenance.
For operators running multiple hydraulic-equipped vehicles, planned maintenance can help create a more structured approach to repairs.
This may involve:
The aim is to reduce avoidable repeat failures rather than replacing components automatically at fixed intervals.
A fleet gives maintenance teams something an individual vehicle cannot: repeated evidence.
If several similar vehicles develop the same problem, it can indicate:
Recurring hydraulic faults across similar vehicles should be treated as useful engineering information. Identifying the pattern can help prevent the same repair being repeated across the rest of the fleet.
Hydraulic fluid condition can affect pumps, valves, cylinders and other components.
Maintenance should consider:
Oil-change intervals should be based on the equipment, operating conditions and manufacturer requirements rather than a universal timetable.
See Hydraulic Oil Change & Filtration Service.
Some fleet hydraulic faults are suited to mobile engineering while others require specialist workshop capability.
| Repair Requirement | Typical Route |
|---|---|
| Burst hydraulic hose | Often suitable for mobile repair. |
| Leaking fitting or adapter | May be suitable for on-site repair once correctly identified. |
| Damaged hydraulic cylinder | Assessment may be mobile; refurbishment is usually workshop-based. |
| Pump or complex component fault | May require diagnosis followed by workshop repair or replacement. |
| Recurring system fault | System diagnosis may be required before further components are replaced. |
See Hydraulic Repair Workshop.
Commercial vehicles do not only develop hydraulic faults during workshop hours.
CH provides 24/7 mobile hydraulic engineering support for urgent breakdowns.
Depending on the fault and available components, attendance can include:
Not every breakdown can be permanently repaired during the first site attendance, particularly where specialist components, machining or cylinder refurbishment are required.
Waste and recycling vehicles can combine several hydraulic functions in one machine.
Systems can include:
Frequent cycles, contamination, weather exposure and demanding operating environments can all influence component life.
Tippers and construction vehicles can require hydraulic support for:
Hydraulic problems should be assessed alongside vehicle condition, cylinder mountings and the working environment.
Vehicle-mounted cranes and grabs use multiple cylinders, hoses, valves and stabilising systems.
Particular attention may be required around:
Hoses should be assessed through the full movement of the equipment because a route that appears acceptable when parked may become stretched, twisted or abraded during operation.
This service is focused on commercial vehicle and mobile fleet hydraulics.
For forklifts and warehouse material-handling equipment, CH also has dedicated hydraulic repair support covering lift cylinders, steering hydraulics, hoses and related components.
See Forklift Hydraulic Repair Services.
Completely Hydraulic operates engineering and trade-counter locations in:
Birmingham and the wider West Midlands are supported through mobile hydraulic engineering.
From Breakdown to Repair
1. Identify the vehicle and hydraulic function
Establish whether the fault involves a tipper, crane, grab, compactor or another system.
2. Understand the symptoms
Confirm whether the issue involves fluid loss, weak performance, abnormal movement, noise or complete hydraulic failure.
3. Make the equipment safe
Control stored pressure, raised loads and moving attachments before repair.
4. Diagnose the failed component
Inspect the relevant hose, fitting, cylinder, pump, valve or wider circuit.
5. Complete the appropriate repair
Carry out mobile work where practical or route specialist component repairs to the workshop.
6. Review repeat faults
Where the same failure is recurring, investigate the underlying cause rather than repeatedly replacing the component.
CH combines mobile engineering with trade-counter supply and specialist hydraulic workshop capability.
This allows fleet operators to access support for:
Good fleet hydraulic support is not just about responding to burst hoses. It means combining mobile repairs, workshop engineering, preventative maintenance and fault diagnosis so recurring hydraulic problems can be identified and individual vehicles can return to productive service safely.
Send CH your fleet type, location and the hydraulic equipment you need support with. For a breakdown, include photographs and details of the failed vehicle or component where possible.
