Solution Definition

The Onchtech straight boom and articulating boom aerial work platform solution is a high-access equipment system designed for work locations where standard access equipment or scaffold-heavy methods cannot efficiently reach the work face.

Core Working Range

It supports 20 m to 40 m+ high-access applications with configurations focused on height, horizontal outreach, platform capacity, terrain mobility, and operational stability.

B2B Fit

The solution is suitable for distributors, rental fleets, EPC contractors, shipyards, industrial maintenance companies, façade contractors, and steel structure construction teams.

Industry Background and Problem Definition

In shipyards, large-span steel structures, stadiums, petrochemical pipe racks, and high-rise landmark façades, elevated work often reaches 20 m to 40 m or more. These environments require more than vertical lifting height. Equipment must remain stable on complex ground, cross over obstacles, and position workers close enough to the target area for welding, coating, installation, inspection, or maintenance.

Traditional scaffolding can require long setup and dismantling cycles, while conventional access vehicles may be limited by insufficient horizontal outreach, restricted platform capacity, visible boom movement at height, or poor mobility on non-hardened jobsites. The key operational question is clear: how can contractors complete continuous high-access work safely and efficiently when the ground is unstable, the work face is blocked, and the load requirement is high?

Typical Pain Points

Platform movement at height: when working above 20 m, insufficient boom rigidity or unstable chassis support can affect operator confidence and work precision.
Blocked approach paths: pits, pipes, steel structures, stored materials, and ground equipment prevent machines from parking near the ideal lifting point.
Limited platform load: workers, welding equipment, spraying tools, façade materials, and repair components may exceed the capacity of standard access equipment.
Restricted terrain access: mud, gravel, soft soil, slopes, and unfinished construction surfaces can delay equipment deployment.

Solution Logic

Onchtech connects aerial work platform engineering with the integrated construction machinery manufacturing capability of Hunan Hongchang Machinery Co., Ltd. The solution combines large working height, long horizontal outreach, high-load platform design, rigid boom structures, stabilizing systems, all-terrain mobility, and lifecycle service support.

Reach Access high and distant work faces when the machine cannot be positioned directly below the work point.

Stability Improve confidence at height through rigid boom structures, chassis support, leveling, and stabilizing mechanisms.

Payload Support multiple operators, tools, and selected materials to reduce repeated lifting cycles.

Mobility Adapt to industrial sites, outdoor construction areas, uneven ground, and non-hardened surfaces.

Key Capability Modules

1. Large-Height Straight Boom and Articulating Boom Platforms

Straight boom platforms are suitable for long-distance outreach and broad area coverage, while articulating boom platforms help operators reach around obstacles and approach complex structures from multiple angles. This configuration is relevant for ship hulls, stadium roofs, steel structures, petrochemical pipe racks, and high-rise façades.

2. Long Horizontal Outreach for Obstacle-Crossing Access

In complex industrial jobsites, the central challenge is often not only maximum height but whether operators can reach the work surface without parking directly beside it. For example, the Onchtech STL-38J offers a maximum working height of 40.2 m and maximum horizontal outreach of 25.4 m, supporting access across pipes, pits, ground equipment, and structural barriers.

3. High-Load Platform Design

Heavy industrial work may require two to three operators plus welding units, spraying systems, hand tools, or installation materials. Onchtech large-boom models can provide 300 kg / 460 kg dual-load capacity, helping reduce interruptions caused by insufficient platform load and improving single-lift operating efficiency.

4. Rigid Boom Structure and Stabilizing Support

High-access stability depends on boom material, structural design, chassis support, and rotation systems. Onchtech equipment uses high-rigidity special steel boom structures, combined with X-type telescopic outriggers and dual slewing reducer design on applicable models, to improve machine stability under large-height and long-outreach operating conditions.

5. All-Terrain Mobility and Jobsite Adaptability

Shipyards, mines, infrastructure jobsites, and municipal projects may include gravel roads, mud, slopes, and non-hardened surfaces. Onchtech platforms can be configured with 4WD, 4WS, high-traction solid tires, or crawler chassis options. The STL-19JC crawler version is suitable for soft ground, muddy areas, and unfinished construction surfaces.

6. Power, Leveling, Remote Service, and Spare Parts Support

Equipment can be fitted with Cummins or Yanmar diesel power systems for outdoor heavy-duty work. Automatic hydraulic platform leveling supports stable operation on uneven ground. Through an AWP remote IoT management platform, Onchtech supports equipment status monitoring, hydraulic data review, maintenance planning, original spare parts supply, remote technical service, and warranty support for overseas customers.

Application Scenarios

Ship Hull Coating, Welding, Grinding, and Inspection

Long outreach allows operators to cross over shipyard obstacles and approach large hull surfaces for coating, welding, repair, and inspection tasks.

Large-Span Steel Structures and Public Buildings

Mobile boom platforms help teams access dispersed high-level nodes for steel installation, bolt fastening, anti-corrosion coating, and maintenance.

Petrochemical Pipe Racks and Industrial Facilities

Articulating configurations help reach around pipes and equipment, while straight boom models support long-distance access for inspection and repair.

High-Rise Façade Installation and Maintenance

High-load platforms support workers with tools, façade materials, and maintenance equipment for curtain wall installation, repair, and cleaning.

Uneven Infrastructure and Municipal Jobsites

Crawler and all-terrain chassis options improve site entry on mud, gravel, slopes, and non-hardened construction surfaces.

Recommended Equipment and Core Parameters

Core Parameter	STL-19JC Crawler Outdoor Version	STL-38J Flagship Super Straight Boom
Maximum working height	20.7 m	40.2 m
Maximum platform height	18.7 m	38.2 m
Maximum horizontal outreach	14.9 m	25.4 m
Rated load	250 kg	300 kg / 460 kg dual load
Chassis and drive	Engineering crawler chassis for soft and muddy ground	4WD, 4WS, high off-road solid tires
Power source	Yanmar-IV diesel engine	Cummins heavy-duty engine
Turntable rotation	360° continuous rotation	360° continuous rotation

Equipment Selection Logic

For soft, muddy, or unfinished ground, prioritize crawler aerial work platforms such as the STL-19JC.
For 40 m-class high-access work, long outreach, and heavy-duty platform loads, prioritize the STL-38J.
When work points are blocked by pipes, steel structures, or building projections, select articulating boom configurations according to site geometry.

Operational Value and Expected Results

Improved High-Access Safety

Rigid booms, stabilizing systems, hydraulic leveling, and chassis support help reduce excessive movement and improve operator confidence at height.

Higher Jobsite Efficiency

Long outreach reduces repositioning frequency, while higher platform loads reduce repeated lift cycles for workers, tools, and materials.

Reduced Scaffold Dependency

For large public buildings, shipyards, and industrial maintenance projects, boom lifts can reduce scaffold setup, dismantling, and transfer requirements.

Better Complex-Site Adaptability

Wheel, crawler, straight boom, articulating boom, and different power options allow customers to match equipment to terrain, height, outreach, and load needs.

Lower Downtime Risk Over the Lifecycle

Remote IoT monitoring, original spare parts, warranty support, and technical service help overseas customers manage maintenance and equipment availability.
