Product Details
TRACKED TELESCOPIC BOOM LIFT
STL-19JC Self-Propelled Tracked Telescopic Boom Lift
The Onchtech STL-19JC is a 19m-class self-propelled tracked telescopic boom lift designed for outdoor elevated work where wheeled access equipment may struggle to travel. Its integrated all-terrain track undercarriage is intended for soft ground, muddy construction areas, uneven access roads and remote open-air sites. The machine helps contractors, equipment rental companies and project buyers position personnel and work tools at height while retaining travel capability across demanding ground conditions.
Elevated Work Capability
20.7 m
Maximum Working Height
This working height supports maintenance, installation and construction tasks above ground level in open outdoor work zones.
250 kg
Rated Platform Capacity
The rated load capacity provides a defined allowance for personnel, tools and task-related materials carried on the platform.
Tracked Mobility
Lower Ground Pressure
The rubber and steel track configuration is designed to reduce ground pressure, an important consideration on soft, wet or loose surfaces.
Rough-Terrain Access
Travel Between Work Points
The tracked undercarriage is suited to moving between outdoor work locations where hard, level site roads are not consistently available.
Power and Jobsite Adaptation
Yanmar IV Engine Power
The STL-19JC is equipped with a Yanmar-IV engine to support self-propelled outdoor operation in remote construction and maintenance locations.
Automatic Hydraulic Chassis Leveling
The automatic hydraulic leveling system is designed to help the machine adapt to inclined and uneven access routes encountered on undeveloped sites.
Platform Rotation of ±80°
Platform rotation allows the working position to be adjusted toward the task area, supporting more precise access around outdoor structures and terrain features.
Application Scenarios
Early-Stage Land Development
For elevated installation or construction tasks on undeveloped ground, the tracked chassis supports access where prepared roads are limited.
Rainy-Season Outdoor Projects
On muddy open-air jobsites, the low-ground-pressure track design is relevant for reaching elevated work areas across softened terrain.
Desert and Coastal Works
For projects near sandy ground or coastal areas, the machine provides a tracked alternative for elevated inspection, fitting and maintenance work.
Scenic Area Maintenance
For outdoor maintenance in landscape-sensitive or remote locations, the boom lift can be used for access to elevated facilities and infrastructure.
Suitable Buyers and Selection Considerations
Suitable for Outdoor Access Requirements
The STL-19JC is relevant for contractors, rental fleets, project procurement teams and equipment distributors serving rough-terrain elevated work applications.
Key Information for Selection
Confirm required working height, platform load, ground condition, access-route slope, surface type and the space available around the intended work area before selection.
Discuss Your Operating Conditions
Share your site terrain, task height and purchasing or brand cooperation requirements with Onchtech to evaluate whether the STL-19JC configuration fits the planned application.
