Product Details
Onchtech Heavy-Duty Telescopic Boom Series
Self-Propelled Telescopic Boom Platform for Medium-Height Heavy-Load Construction
Onchtech STL-22J is a self-propelled telescopic boom lift featuring a straight telescopic boom system, providing upward reach for industrial high-altitude construction. The machine is designed for engineering contractors, equipment rental companies, project purchasers, and industrial facility operators, suitable for plant expansions, building facade installations, and cable tray and pipe assembly tasks that require carrying substantial tools or construction components. Its core selection value lies in combining a 24m maximum working height with dual load capacities of 300kg/460kg, helping project teams reduce repeated transport of equipment and materials during continuous high-altitude operations.
Aerial Work Capability
24 m
Maximum Working Height
Designed to cover medium-height installation, inspection, and assembly positions, suitable for projects requiring continuous work on higher facades or plant structures.
300 / 460 kg
Dual Load Capacity
Corresponds to platform rated load requirements within different working envelopes, facilitating the transport of personnel, tools, and heavier construction components for high-altitude operations.
4WD
Four-Wheel Drive
Suitable for movement across paved construction site roads and between different work points; actual passability should be confirmed based on on-site slopes and ground conditions.
Telescopic Boom
Rigid High-Altitude Work Platform
Matching the extension characteristics of the straight boom structure, providing stable and rigid platform support for continuous medium-height construction work.
Power and Chassis Configuration
Cummins Engine Power
STL-22J is equipped with a high-performance Cummins engine, providing the power foundation for driving and high-altitude operation of this large self-propelled telescopic platform, suitable for industrial sites and outdoor engineering projects.
Fully Automatic Hydraulic Self-Leveling Chassis
The chassis features a fully automatic hydraulic self-leveling configuration to adapt to changes in on-site ground conditions. Prior to use, on-site assessment should still be conducted based on load-bearing capacity, slopes, and operational requirements of the work area.
Brand and Customization Cooperation
Leveraging the construction machinery manufacturing system of Hunan Hongchang Machinery Co., Ltd., Onchtech is available for OEM, ODM, or OBM discussions regarding branding and cooperation needs.
Application Scenarios
STL-22J's telescopic boom operation and heavy-load platform capability are suitable for engineering tasks that require delivering workers, installation tools, and components together to medium-height work positions.
Industrial Plant Expansion
Used for high-altitude installation and maintenance of steel structures, roofing, and equipment areas. The 24m working height supports coverage of medium-height construction points.
Glass Curtain Wall Installation
Suitable for lower-zone facade construction of office buildings. The straight telescopic boom allows operators to reach installation positions while carrying required tools.
Cable Tray and Pipe Assembly
During continuous high-altitude assembly of cable trays, pipes, and similar systems in electromechanical installation areas, the 460kg load configuration accommodates the need to carry heavier components.
Suitable Buyers and Selection Considerations
This self-propelled telescopic boom lift is suitable for procurement customers involved in industrial construction, building installation, electromechanical engineering, and equipment rental businesses, particularly for projects with specific requirements for working height, platform load, and on-site mobility. When selecting, it is recommended to prioritize confirming the actual working height, total load of personnel and tools or materials, on-site ground conditions, access routes in the work area, and project schedule. After providing this operational information, the Onchtech team can assist you in further verifying the suitability and cooperation configuration requirements of the STL-22J.
