Working Principle & Construction Process Of Truck-Mounted Green Trimming Equipment｜Integrated SideFlat Cutting & Slope Mowing: Multi-condition Trimming Unit Improves Road-maintenance Efficiency

Landscaping maintenance for expressways and provincial-national highways is an essential part of road-operation work. Tasks include median-strip hedge shaping, roadside shrub trimming, slope weed clearing and tree-branch pruning. Traditionally, most of these works rely on manual operators holding petrol-powered hedge trimmers and chainsaws.

Manual trimming brings heavy physical workload and low working speed. When working alongside fast-moving traffic, ground maintenance staff face serious traffic-safety risks. In addition, manually-cut surfaces are uneven, requiring secondary re-trimming, which pushes up overall maintenance expenditure.

The Fannord FND-HS620 intelligent dual-arm full-hydraulic comprehensive trimming machine is a new-generation truck-mounted dual-arm hydraulic maintenance working set. Installed on truck chassis, it adopts full-hydraulic driven dual-arm actuators to realize flat cutting, side cutting, slope mowing and high-branch trimming all-in-one. It meets multi-scenario road-greening requirements and solves real-world maintenance pain points in safety, productivity and trimming quality.

1. Core Working Principle

This road greening truck-borne trimming platform consists of six key modules: truck-mounted bearing chassis, power unit, full-hydraulic control system, primary-&-secondary mechanical arms, quick-change cutting-head tools and wireless remote-control module.

1. Power supply unit: Yuchai diesel engine delivers motive power for the whole hydraulic system.

2. Full-hydraulic driving system: Hydraulic pump station outputs high-pressure hydraulic oil, controlling rotation, folding and telescopic movement of dual arms, meanwhile driving cutting heads for high-speed rotary cutting.

3. Dual-arm mechanical actuator - Main arm: 3-section folding plus 1000mm telescopic structure, 360° slewing range, max trimming height up to 6500 mm. Mainly for median-strip flat trimming and high-altitude tree-branch pruning. - Auxiliary arm: 2-section folding arm, max trimming height 2000 mm, mostly for oblique side trimming. It enables simultaneous flat-and-side cutting.

4. Quick-change cutting-head tools: Hedge-trimming head, high-branch cutting head and slope-mowing head can be swapped rapidly. Blades adopt flexible connection, driven by hydraulic motors rotating at 2600-3000 r/min to cut shrubs and weeds.

5. Wireless remote-control system: Operators hold LCD-equipped remote controllers to adjust arm postures and start/stop cutting heads from safe distance away from traffic lanes, greatly enhancing personal safety.

2. Standard On-site Construction Workflow

This truck-mounted hedge-shaping unit is fixed onto truck cargo bed and moves along roads. Standard workflow contains five phases:

1. Pre-work Preparation Secure equipment on truck bed, check engine oil and hydraulic-oil level. Install corresponding cutting-head (hedge head / slope-mowing head / high-branch head) according to assignment. Test wireless remote-control signal to verify response of arms and cutters. Drive working truck into maintenance section and activate traffic warning signs.

2. Positioning & Arm Deployment Drive slowly to work starting point. Operator stays in safe zone away from traffic, uses remote-control to unfold, slew and extend dual arms, position cutting heads to target trimming area.

3. Carry-out Trimming Operation Truck keeps low-uniform speed. Start high-speed rotation of cutting heads by remote control. - Median-strip maintenance: Main arm for top flat cutting; auxiliary arm completes side oblique trimming at same time. -Road-side high branches: Lift main arm for high-altitude branch pruning. - Slope weeding: Fit slope-mowing head, lower arm onto inclined slope surface to clear slope weeds.

4. Working-condition Switch-over Mid-job Park truck safely roadside. Stop machine, swap cutting heads quickly without complicated disassembly, switch freely between flat-cutting, slope-mowing and high-branch-pruning modes.

5. Work Completion & Retraction After finishing section work, shut down cutting heads. Remote-control folds and retract dual arms into safe stowed position. Turn off diesel engine. Inspect blades and hydraulic hoses for wear. Complete routine maintenance, remove traffic warning devices and exit work zone.

3. Multi-condition Compatibility & User-oriented Benefits For Highway-maintenance Contractors

✅ Improved personnel safety: Remote wireless operation keeps operators out of high-risk traffic zones, lowering traffic-accident risks and potential accident-compensation liabilities.

✅ Sharp productivity gain: Dual-arm simultaneous flat-&-side cutting completes double-sided hedge shaping within one pass. Output multiplies compared with pure manual labour. Shorten road-closure time and lessen disturbance to public traffic.

✅ Uniform trimming finish: High-speed cutter delivers neat even cutting surfaces, minimal secondary manual touch-up required, improving overall highway-landscape consistency.

✅ High-asset-utilization rate: This truck-mounted garden cutting gear handles median-strip flat-cut, side-cut, slope-mowing and high-branch pruning in one unit. No need to purchase multiple single-function machines, reducing total capital expenditure.

✅ Lower labour cost: Cut number of on-site workers, ease labour-shortage and rising-labour-cost pressure for road-maintenance departments.

4. Application Scope & Operation Remarks

1. Main application scenarios: Median-strip hedge shaping, roadside shrub trimming, slope weed removal, medium-height roadside-tree pruning for expressways & provincial-national highways.

2. Important notes - Inspect hydraulic hoses before work to avoid oil leakage hazards. - Match rotating speed against branch thickness, prevent violent hard-branch impact to cutter heads. - Place complete traffic warning signs for road-side operation; keep truck at low travelling speed.

Conclusion

Pure manual operation can hardly satisfy modern-day requirements for efficiency and safety in large-scale highway green-maintenance projects. As a capable highway truck-bush-trimming device, Fannord FND-HS620 intelligent dual-arm full-hydraulic trimming unit integrates flat-cutting, side-cutting, slope-mowing and high-branch pruning in one single machine. Combined with truck-borne mobility and wireless remote-control, it balances safety, working speed and trimming quality, delivering an efficient solution for landscaping maintenance on expressways and provincial-national highways.
