Preparing the right spare parts is an important part of buying and operating a truck mounted crane, especially for overseas buyers. Hydraulic hoses, seals, filters, pins, bushings, fasteners, remote-control parts, electrical connectors, hook components and outrigger parts can prevent long downtime when a small failure occurs.
This guide explains which spare parts buyers should prepare, how to match them to the crane configuration, and what information should be requested from the supplier before shipment.

1. Why Spare Parts Planning Matters
Truck mounted cranes work outdoors under dust, rain, vibration, hydraulic pressure and repeated loading. A worn seal, damaged hose or missing connector can stop a project even when the main crane is in good condition. For overseas buyers, replacement delivery may take days or weeks, so a basic package ordered with the crane is practical.
- Reduce equipment downtime and emergency international shipping
- Maintain safe operation and support local maintenance teams
- Extend service life and reduce long-term operating costs
- Keep dealers and fleet owners ready to support multiple cranes
2. Hydraulic Hoses and Fittings
Hydraulic hoses control lifting, lowering, boom extension, slewing and outrigger movement. Buyers should prepare hoses, fittings, protective sleeves and clamps that match the crane model and hydraulic layout. Common failures include leakage, aging, cracks, friction damage, loose fittings and burst hoses.

Request a hose list with inner diameter, length, pressure rating, fitting type and part number so local technicians can identify replacements quickly. Related troubleshooting is covered in common hydraulic problems in truck mounted cranes.
| Spare part | Why it is needed |
|---|---|
| Hydraulic hose | Replaces damaged or leaking hoses |
| Hose fittings | Connects hoses to valves and cylinders |
| Protective sleeves | Reduces friction and outdoor wear |
| Hose clamps | Keeps routing secure |
| Joint seals | Prevents leakage at connections |
3. Seals and O-Rings
Seals and O-rings are used in hydraulic cylinders, control valves, pumps, rotary joints, outrigger cylinders and boom extension cylinders. Worn seals can cause oil leakage, pressure loss, cylinder drift, slow movement and higher maintenance cost. Because they are small and inexpensive, it is useful to keep complete seal kits in the spare parts package.
4. Hydraulic Oil Filters
Dirty hydraulic oil damages pumps, valves, cylinders and seals. Prepare return filters, suction filters, pressure filters where equipped, breather filters and tank filter parts. Replacement intervals depend on working frequency, dust, temperature, oil condition and the manufacturer maintenance schedule.
5. Pins and Bushings
Pins and bushings carry load at boom joints, folding connections, cylinder mounts, outrigger joints, hook blocks, lifting arms and linkages. Wear can create looseness, abnormal noise, vibration, poor alignment and unstable movement. Lubrication extends life, but correct replacement dimensions should be kept on file.

6. Bolts, Nuts and Fasteners
Inspect fasteners at the crane base, sub-frame, slewing system, outriggers, hydraulic components, control station, electrical boxes, boom accessories and mounting brackets. Safety-related fasteners must match the required size and grade; low-quality substitutes should not be used.
7. Hook, Safety Latch and Lifting Accessories
Prepare hook safety latches, hook-block components, shackles, lifting slings, pulleys, swivels, load chain and wire rope when a winch is fitted. A damaged latch can allow a load to slip. Buyers should confirm which attachments are included with the crane and order compatible spares. See the key safety features of a truck mounted crane.
8. Remote Control Batteries and Components
Wireless remote control systems improve operator visibility but require spare batteries, charger, transmitter parts, receiver components, emergency-stop parts, switches, protective covers and antennas where applicable. Water damage, weak signal and damaged buttons can delay operation.

9. Electrical Connectors and Switches
Common electrical spares include connectors, switches, fuses, relays, cable plugs, control-box parts, emergency-stop switches, warning-light parts, sensor cables and wiring terminals. Vibration, moisture, corrosion, dust and poor contact are common causes of electrical failure.
10. Outrigger-Related Spare Parts
Outriggers are essential for stability. Useful parts include cylinder seals, outrigger pads, control-valve parts, pins, hose fittings, sliding blocks, locking parts, support feet and hydraulic hoses. Inspect the system before each lift, especially when working on uneven ground or construction sites.
11. Hydraulic Valve and Cylinder Parts
Keep valve seals, solenoid parts, cylinder seal kits, pressure gauges, hydraulic connectors, valve handles, control levers and pressure-relief components. Buyers do not always need complete cylinders or valve blocks, but should record the crane model, hydraulic diagram, cylinder specifications and valve information.
12. Spare Parts for Different Crane Types
Knuckle Boom Truck Mounted Crane
- Joint pins and bushings
- Folding-cylinder seals
- Hoses around boom joints
- Remote-control and outrigger parts
Telescopic Boom Truck Mounted Crane
- Extension-cylinder seals
- Sliding blocks and boom wear pads
- Guide parts, hoses, pins and bushings
Mini Truck Crane
- Small hydraulic hoses and cylinders
- Electric control and battery parts
- Hook and lifting accessories
Truck Mounted Crane with Winch
- Wire rope and rope guides
- Pulley, brake and hook-block parts
The exact list must follow the actual crane configuration, working frequency and application.
13. Recommended Spare Parts Package for Overseas Buyers
A practical package usually includes common wear parts rather than complete major assemblies. Confirm the quantity according to model, application, working hours and destination support.
| Category | Suggested spare parts |
|---|---|
| Hydraulic system | Hoses, fittings, seals, O-rings, filters |
| Mechanical joints | Pins, bushings, bolts, nuts, washers |
| Control system | Remote batteries, switches, connectors |
| Outriggers | Seals, pads, pins, sliding blocks, fittings |
| Lifting accessories | Hook latch, shackles, slings, wire rope if equipped |
| Electrical system | Fuses, relays, plugs and emergency-stop switch |
| Maintenance items | Grease, filter elements and pressure gauge if needed |
14. What Buyers Should Ask the Supplier Before Shipment
- Which spare parts are recommended for this model?
- Which parts are easy to wear?
- Can you provide part numbers and specifications?
- Are the hydraulic hoses standard or customized?
- Which filters need regular replacement?
- Can parts be shipped separately later?
- What should a dealer keep in stock?
- Can spare parts be identified from photos or videos?
- Can you provide maintenance guidance?
A reliable supplier should recommend parts according to crane configuration and working environment. Buyers can also review what to check in a truck mounted crane load test before shipment.
15. How to Store Spare Parts Properly
- Keep seals and O-rings away from sunlight and heat
- Store hydraulic hoses in a dry place
- Protect electrical parts from moisture
- Label parts by crane model and part number
- Keep small parts in organized boxes with photos
- Do not mix parts from different models
- Check storage condition regularly
