Product Details
ONCHTECH TRACKED TELESCOPIC BOOM LIFT
STL-22JC 22m Tracked Telescopic Boom Lift
The Onchtech STL-22JC is a tracked telescopic boom lift developed for outdoor elevated work where uneven ground, remote access routes and heavy materials make conventional wheeled equipment less suitable. With an all-terrain tracked chassis and a maximum working height of 23.55 m, it is designed for construction contractors, utility service providers, telecom operators and project procurement teams carrying out demanding field work. The machine supports elevated access for installation, inspection and construction tasks while helping crews bring personnel, tools and required materials to the work position in a single lift.
Aerial Work Capability
23.55 m
Maximum working height
This is the maximum reachable working height for elevated tasks such as power-line installation, telecom tower assembly and exterior construction. It should be distinguished from platform height, which is not stated here.
460 kg
Rated platform capacity
The heavy-load platform is intended for personnel, tools and work materials. According to the supplied product specification, the 460 kg mode allows up to three people to work in the basket together.
Tracked mobility
For uneven outdoor access
The all-terrain tracked chassis is suited to rugged outdoor routes, unpaved project areas and uneven terrain. Actual travel and setup conditions should still be assessed according to ground bearing capacity and site conditions.
Power and Platform Positioning Features
Weichai high-torque engine
The STL-22JC is equipped with a Weichai high-torque engine to support the power demands of outdoor tracked travel and elevated construction work in field environments.
Automatic leveling on slopes up to 5°
A one-button automatic leveling system is specified for working slopes up to 5 degrees, helping maintain a level platform position when the machine is set up on qualified sloped ground.
90° basket rotation
The basket supports 90-degree rotation, allowing the work area to be oriented toward installation points, structural surfaces or equipment locations without changing the overall task layout.
Onchtech can also support OEM, ODM and brand-identification adaptation for B2B customers whose markets require differentiated equipment configurations.
Application Scenarios
Power transmission projects
For outdoor transmission-line erection and maintenance, the tracked chassis supports access across uneven project areas while the working height serves elevated installation tasks.
Telecom tower assembly and service
For field-based telecom sites, crews can use the 460 kg platform capacity to bring personnel, service tools and installation materials up to the required work area.
Mountain and landscape infrastructure
For special construction in hilly, landscaped or irregular outdoor environments, the machine is intended for projects where ground conditions require tracked access and controlled platform leveling.
Heavy exterior construction
For early-stage open-air facade work, the telescopic boom lift provides elevated access where workers need to handle larger tool and material loads at height.
Suitable Customers and Selection Considerations
The STL-22JC is relevant for construction contractors, power and utility service companies, telecom infrastructure teams, equipment distributors and project buyers handling heavy-duty outdoor elevated work. It is particularly suitable when the job combines a working-height requirement of up to 23.55 m, a need to carry substantial platform loads and access conditions that favor a tracked chassis.
For selection discussion:
provide the required working height, combined personnel and material load, ground condition, slope condition, access route and main task type. The Onchtech team can use this information to help assess whether the STL-22JC configuration fits the intended project application.
