Product Details
DIESEL ROUGH-TERRAIN BOOM LIFT
STL-19J Self-Propelled Straight Boom Lift
The Onchtech STL-19J is a diesel-powered, self-propelled straight boom lift designed for elevated outdoor work where both vertical access and long horizontal outreach are required. Positioned in the popular 19 m class, this model provides a maximum working height of 21 m for bridge, advertising, landscaping, and construction access tasks. Its rough-terrain drive configuration supports contractors, rental fleets, project purchasers, and equipment distributors working across changing site conditions.
High-Reach Working Capability
21 m
Maximum working height
Provides elevated access for tasks such as high-level installation, inspection, maintenance, and exterior construction work.
14.9 m
Maximum horizontal outreach
The straight telescopic boom reaches over obstacles or offsets, which is important when work points cannot be positioned directly below.
45%
Gradeability
Supports travel on appropriately prepared slopes between work areas, helping equipment movement on outdoor jobsites with changing elevations.
0.45 m
Ground clearance
The elevated clearance is relevant for outdoor surfaces with ruts, uneven sections, or site debris that may limit lower-profile machines.
Diesel Power and Rough-Terrain Mobility
The STL-19J is equipped with a Yanmar diesel engine and a full-time four-wheel-drive system. This combination is intended for outdoor elevated work where the machine needs to travel between access points across non-flat or less-finished site surfaces. For rental and project fleets, the diesel configuration makes the model a practical option for construction zones, municipal works, and other open-air applications that require independent machine movement.
Application Scenarios
Bridge Underside Construction
For inspection, repair, or installation work beneath elevated bridge sections, the 14.9 m horizontal outreach helps access work areas set back from the machine’s travel position.
Outdoor Billboard Installation
Suitable for assembling or closing large outdoor advertising structures where personnel require elevated access and reach beyond the immediate machine position.
Urban Tree Pruning
For municipal landscaping and mature-tree maintenance, the straight boom can provide elevated access around dense foliage while the 4WD system supports movement on outdoor grounds.
Suitable Customers and Selection Considerations
The STL-19J is suited to aerial work platform rental companies, construction contractors, municipal maintenance teams, equipment dealers, and project buyers that need diesel-powered straight-boom access for outdoor work at up to 21 m working height. Selection should consider the required working height, horizontal distance to the task, access-route surface conditions, slope, and available space around the work area. Onchtech can support B2B customers with product configuration and OEM/ODM cooperation discussions based on the intended market and operating conditions.
