A 14m diesel self-propelled boom lift is one of the most popular models in the aerial work platform (AWP) category—balancing reach, mobility, and power.
This guide covers everything you need to know about 14m diesel-powered articulated/telescopic boom lifts, including technical parameters, performance metrics, safety features, pricing trends, and procurement tips—so you can make an informed purchase.
1. What is a 14m Diesel Self-Propelled Boom Lift?
A diesel self-propelled boom lift is a type of aerial work platform designed to lift workers and tools to elevated positions safely. Powered by a diesel engine, it is independent of external power sources, making it ideal for outdoor, rough-terrain applications.
The 14m designation refers to the maximum platform height or working height:
Platform height = height from ground to the platform floor (usually 12m for this model).
Working height = platform height + 2m (the height a worker’s hands can reach), totaling 14m.
Self-propelled means the lift can be driven and repositioned without lowering the platform, improving efficiency.

3. Key Features and Advantages
1. High Mobility & Rough-Terrain Capability
Diesel engine + 4×4 drive: Delivers enough torque for muddy or uneven worksites.
Oscillating axles: Maintain wheel contact on rough terrain for stability.
Gradeability up to 40%: Can climb steep construction site slopes.
2. Extended Horizontal Outreach
Reach obstacles (trees, walls, machinery) without repositioning the base.
Ideal for facade maintenance, steel structure installation, and billboard work.
3. Versatile Boom Configurations
Articulated boom: Up-and-over access to clear obstacles.
Telescopic boom: Longer horizontal reach for open-area work.
4. Operator Efficiency
Self-propelled control from the platform: Drive and lift simultaneously.
Proportional control system: Smooth, precise movement.
360° turret rotation: Full-area coverage without moving the chassis.
5. Safety Systems
Overload sensing with alarm.
Tilt protection cut-off.
Emergency lowering system.
Non-marking or foam-filled tyres to prevent punctures.
4. Common Applications
| Industry | Example Tasks |
|---|---|
| Construction | Steel structure assembly, curtain wall installation, roof work. |
| Maintenance | Factory equipment repair, lighting replacement, facade cleaning. |
| Tree Care | Trimming tall trees, arborist access. |
| Telecom & Utilities | Installing antennas, repairing power lines. |
| Event Setup | Stage lighting, outdoor billboard installation. |
5. Market Price Trends (China Factory Reference)
China is one of the largest manufacturing bases for diesel boom lifts. Prices vary by brand, configuration, and export market requirements.
2025 China Factory FOB Price Range (USD):
| Type | Model Height | Price Range (USD) | Notes |
|---|---|---|---|
| Articulated Boom Lift | 14m | $22,000 – $38,000 | Most common; good up-and-over reach. |
| Telescopic Boom Lift | 14m | $25,000 – $42,000 | Longer outreach; better for open sites. |
Price Influencers:
Engine brand: Perkins/Yanmar cost more than Chinese diesel engines.
Control system: CAN bus and load-sensing systems add cost.
Options: Generator, air lines to platform, cold-weather package.
Certification: CE, ANSI, or CSA compliance increases cost.
6. Operational Cost Considerations
Fuel Consumption – 2–4 liters/hour depending on engine size and load.
Maintenance – Engine oil, hydraulic oil, filters every 250 hours.
Tyres – Foam-filled tyres cost more but reduce puncture downtime.
Depreciation – Typically 8–12% per year in heavy rental use.
7. Comparison: Diesel vs. Electric Boom Lift (14m)
| Feature | Diesel | Electric |
|---|---|---|
| Power Source | Diesel engine | Battery pack |
| Terrain | Best for outdoor/rough | Smooth indoor floors |
| Noise | 80–90 dB | 60–70 dB |
| Emissions | Yes (Stage V/ Tier 4 final engines cleaner) | None |
| Run Time | Continuous with refuel | 6–10 hours per charge |
| Price | Similar or slightly higher | Similar |
8. Buying Advice from Huichuang Lift
When selecting a 14m diesel self-propelled boom lift, consider:
A. Application & Site Conditions
For confined sites with many obstacles: Choose articulated model.
For open spaces with far reach requirements: Choose telescopic.
B. Engine & Performance
If used in cold climates, choose an engine with pre-heating.
Verify Stage V / Tier 4 Final emission compliance if exporting to EU/US.
C. Transport & Storage
Check transport height (under 2.4m is easier for shipping in containers).
Weight must match your crane/trailer capacity.
D. Service & Parts
Choose brands or suppliers with readily available spare parts.
Ask for hydraulic/electrical schematics for future repairs.
E. Budget & Total Cost of Ownership
Consider not just purchase price but lifetime running costs.
If used <500 hours/year, consider buying used or leasing.
9. Safety and Regulatory Compliance
A reputable 14m diesel boom lift should comply with:
ISO 16368:2022 (MEWP safety standard)
CE marking (Europe)
ANSI A92.20 (USA)
CSA B354 (Canada)
Always:
Train operators per IPAF or local certification.
Perform daily pre-use inspections: hydraulic leaks, tyre condition, safety devices.
Never exceed the Safe Working Load.
