Product Details
Onchtech Ultra‑High Access Equipment
STL-42J 42m Self‑Propelled Telescopic Boom Lift
STL-42J is a self‑propelled telescopic boom lift from Onchtech designed for ultra‑high construction. With its telescopic straight boom structure, the working envelope extends to nearly 44 meters. The machine is suitable for specialized curtain wall installation on mid‑ and low‑rise sections of large buildings, as well as high‑altitude inspection and emergency repair tasks in core areas of petrochemical and smelting facilities. It assists engineering contractors, equipment rental companies, and industrial maintenance teams in equipment selection for operations requiring long‑reach, high‑position platform access.
Aerial Work Capability
Key parameters of STL-42J are configured around ultra‑high platform positioning, load capacity, and high‑altitude mobility, serving as a fundamental basis for assessing working height and platform task requirements on large projects.
Maximum Working Height 43.8m
The maximum working height refers to the highest position reachable by personnel and tools on the platform, suitable for tasks requiring coverage of high‑rise building facades and elevated areas of large industrial installations.
Maximum Platform Height 41.8m
The platform height is the maximum elevation of the platform floor, while the 43.8m working height corresponds to the equipment's positioning height and the actual working coverage for personnel.
Platform Rated Load 480kg
The 480kg rated load provides a configuration basis for carrying personnel, construction tools, and corresponding materials, making it suitable for curtain wall installation and industrial maintenance tasks that require transporting substantial work materials.
Telescopic Boom and 4‑Wheel Drive Configuration
High‑Purity Steel Telescopic Boom
The machine features a high‑purity steel telescopic boom designed for platform operations in ultra‑high extension conditions. The product emphasizes smooth response to micro‑motion commands, suitable for precision construction tasks with high requirements for platform end‑feel.
4WD Four‑Wheel Drive & 4WS Four‑Wheel Steering
Standard 4WD and 4WS configurations are provided for equipment mobility and steering between different work points on project sites. These configurations should be evaluated in conjunction with on‑site paving conditions, slopes, passage dimensions, and ground conditions.
Elevated Travel Speed 1.1km/h
At maximum height and 480kg full load, the machine's elevated travel speed is 1.1km/h, providing a parameter reference for construction scheduling that requires fine positioning and short‑distance movement within the same work area.
Onchtech can discuss OEM, ODM, and branding adaptation matters based on project procurement or brand cooperation requirements. Specific configurations are subject to mutually confirmed product documentation.
Application Scenarios
As a 42‑meter self‑propelled telescopic boom lift, STL-42J is suitable for high‑altitude construction projects with clear requirements for working height, platform load, and on‑site mobility.
High‑Rise Curtain Wall Installation
Used for installation, adjustment, and hanging of specialized curtain walls on mid‑ and low‑rise sections of landmark buildings. The 43.8m working height provides coverage for high‑level facade tasks.
Emergency Repairs in Core Areas of Petrochemical Plants
Suitable for areas with limited tower crane coverage, allowing maintenance personnel to carry tools and materials to elevated work positions for urgent repairs.
High‑Altitude Maintenance in Smelting Facilities
Designed for inspection, maintenance, and component handling of large equipment and structures in smelting plants. The 4WD and 4WS configuration facilitates relocation according to on‑site road conditions.
Suitable Buyers and Selection Considerations
STL-42J is suitable for ultra‑high‑rise building construction contractors, aerial work equipment rental companies, petrochemical and smelting project purchasers, and industrial maintenance service providers, especially for projects requiring nearly 44 meters of working coverage, 480kg platform rated load, and 4WD/4WS configurations.
Procurement consultation suggestion: Please provide the target working height, required platform load, on‑site ground and ramp conditions, access space in the work area, project timeline, and purchase or rental purpose. The Onchtech team can assist in verifying the compatibility of STL-42J with your actual operating conditions and discuss corresponding cooperation and delivery arrangements.
