Product Details
Diesel Self-Propelled Telescopic Boom Lift
STL-26J for Long-Reach Facade Construction
Onchtech STL-26J is a 26‑meter‑class self‑propelled telescopic boom lift with a maximum working height of 28 meters. Featuring a steel telescopic boom structure and diesel power, it is designed for professional high‑altitude tasks such as exterior wall assembly, facility maintenance, and large‑area surface treatment. Its long horizontal reach and heavy‑load configuration make it an ideal choice for engineering contractors, equipment rental companies, port operators, ship repair enterprises, and industrial project purchasers working in open outdoor sites.
Aerial Work Capability
28m Working Height
Maximum Working Height
Indicates the maximum height the machine can reach, suitable for mid‑rise industrial building facades, port structures, and other elevated work positions.
18m Horizontal Reach
Horizontal Work Coverage
The telescopic boom can extend over long distances to the work surface, providing coverage for locations with spacing from equipment, pipelines, or building exteriors.
300kg / 460kg Load
Dual Load Configuration
Two rated load configurations are available to accommodate personnel, tools, and on‑site materials, allowing selection based on task requirements.
45% Gradeability
On‑Site Ramp Passability
Suitable for traversing ramp sections between different work points on paved sites; actual passability should be verified against ground conditions and site‑specific factors.
Diesel Power and Heavy‑Load Construction Adaptation
Cummins Engine Power
STL-26J comes standard with a Cummins engine, providing the power foundation for lifting, extension, and on‑site movement during outdoor high‑altitude construction.
160L Fuel Tank Capacity
The large fuel reserve is suitable for high‑load, continuous operation scheduling. Purchasers can evaluate this based on shift duration and on‑site refueling conditions.
Steel Telescopic Boom Structure
The long straight boom establishes a direct access path to elevated targets, suitable for tasks such as exterior wall assembly and ship hull surface treatment that require long‑distance approach to the work surface.
Onchtech can discuss OEM, ODM, or OBM adaptation requirements based on your brand identity and cooperation model.
Application Scenarios
Port Facility Inspection and Maintenance
Used for inspection, installation, and maintenance of dock facilities, loading areas, and elevated structures, leveraging the long horizontal reach for comprehensive coverage.
Ocean‑Going Cargo Vessel Hull Treatment
Designed for large‑area rust removal, paint stripping, and other high‑altitude tasks on ship hulls. The heavy‑load platform can support tools and construction materials configured for the job.
Industrial Park External Component Assembly
Suitable for installation and maintenance of external components on mid‑rise industrial buildings, enabling targeted access to facades from accessible machine parking positions.
Suitable Buyers and Selection Considerations
STL-26J is suitable for engineering construction, ship repair, port operations, and industrial installation projects requiring a 28m working height, 18m horizontal reach, and high platform load capacity. Before selection, it is recommended to clarify the horizontal distance between the highest work position and the machine parking point, the total load of personnel and tools/materials, site slope and ground conditions, and the duration of continuous operation. Hunan Hongchang Machinery Co., Ltd. can further verify the configuration suitability and cooperation requirements of the STL-26J based on this operational information.
