Highway green maintenance is plagued by scattered working sites, complex working conditions, low manual efficiency and high risks on high-altitude and slope operations. Under conventional manual labor or single-boom vegetation cutter solutions, median barrier shrubs, roadside hedges, slope weeds and arbor overhanging branches require multiple separate working procedures and repeated site mobilization, resulting in long overall maintenance cycles and heavy labor input. The FND-HS620 Intelligent Dual-boom Full-hydraulic Multi-purpose Green Maintenance Attachable Unit developed by Fanode adopts dual independent boom structures, quick-change working attachments and remote-controlled full-hydraulic actuation system. It enables multi-station simultaneous operation and shortens the overall green maintenance project duration by 60% under comprehensive working scenarios. This paper analyzes the underlying logic of construction period reduction from operation mode, equipment performance, working-condition adaptability and safety management. Comparative tables are provided to elaborate its core values, offering references for mechanization upgrading of highway greening maintenance.
Traditional green maintenance mainly relies on handheld chain saws, manual hedge trimmers and single-boom vegetation pruners. The construction period is fragmented by numerous non-value-added procedures. Main pain points are listed below:
1. Serial working sequences without parallel capacity. Trimming median barrier top surface, side inclined faces, slope weeds and arbor branches are completed step-by-step. Repeated site mobilization, machine relocation and commissioning consume massive working hours.
2. Limited-function implements with tedious replacement. Single-purpose cutting implements can only handle one type of vegetation. Operators have to disassemble and refit attachments repeatedly between hedge trimming and slope mowing, which brings heavy time loss.
3. Insufficient working coverage. Human workers cannot reach steep slopes and high branches. Single-boom cutters only process one direction per pass, requiring repeated vehicle traveling back and forth. Empty driving time accounts for a large share of total project hours.
4. Safety constraints reduce effective output. Manual crews need extensive traffic protection setup. Human physical limits restrict daily effective working hours.
The following table compares conventional maintenance workflows and the FND-HS620 dual-boom vegetation-cutting platform:
Comparison Item | Conventional Manual / Single-boom Trimmer Mode | FND-HS620 Dual-boom Vegetation-cutting Platform Mode |
Operation Logic | Serial procedures with multiple site arrivals | Dual-boom parallel processing, multi-task finished in one single site access |
Concurrent Working Stations | 1 | 2 independent working stations |
Attachment Replacement | Complicated disassembly & time-consuming | Rapid switch of dedicated implements for hedges, high branches and slopes |
Maximum Working Height | Max 2.5 m for manpower; 4-5 m for single-boom machines | Max trimming height of main boom: 6500 mm |
Control Solution | Hand-held manual / on-board single-operator control | Wireless remote control with LCD display |
Slewing & Folding Capacity | Limited slewing angle and folding stroke | 360° full slewing, 210° folding, 1000 mm telescopic stroke |
Site Access Times per Road Section | ≥3 times | 1-time access for multi-condition tasks |
Safety Risk | Workers exposed to traffic hazards and slope falling risks | Operators work remotely away from hazardous zones |
In conventional workflows, operators carry out median top trimming → relocation & commissioning → median side trimming → re-relocation & commissioning → slope mowing → high-branch pruning in strict sequence. Every procedure includes vehicle repositioning, machine setup and safety arrangement.
The FND-HS620 is fitted with a main cutting assembly (3-section folding plus telescopic boom) and an auxiliary cutting assembly (2-section folding boom). Two independent manipulators can deliver cutting motions simultaneously without mutual interference. - Scenario 1: Highway median maintenance: The main manipulator trims horizontal median shrubs while the auxiliary manipulator cuts inclined side faces. Both top and side trimming are accomplished in one single vehicle pass without repeated driving. - Scenario 2: Provincial & national highway maintenance: The main manipulator prunes overhanging arbor branches on road right side, while the auxiliary manipulator processes roadside hedges concurrently. Multiple vegetation types are finished in one pass.
Schedule benefit: Tasks that previously demand 2-3 vehicle passes can be completed within one travel. It eliminates repeated transit, repeated safety setup and repeated equipment commissioning, serving as the top-ranked root cause for 60% project duration reduction.
This truck-mounted vegetation-processing workstation is equipped with complete sets of dedicated working implements: hedge cutting heads, high-branch cutting assemblies and slope mowing modules. These attachments cover median barriers, roadside bushes, slope weeds and arbor branches.
In traditional projects, hedge trimming, slope grass cutting and arbor pruning need separate hedge cutters, grass mowers and high-branch pruners. Multiple fleets require separate dispatching, transportation and site entry. Each equipment arrival demands safety briefing and site preparation, creating waiting intervals across the whole project timeline.
All implements of this truck-mounted hydraulic cutting unit adopt standardized hydraulic interfaces for fast replacement. One single host unit covers all maintenance scenarios. One-time site access replaces batches of separate equipment arrivals, removing schedule gaps caused by multi-team mobilization.
Key implement specifications are summarized in the table below:
Implement Name | Model | Effective Working Width | Max Rotational Speed | Applicable Boom | Typical Application |
Hedge Cutting Head | CS1500 | 1500 mm | 3000 r/min | Main Boom | Horizontal & vertical median hedge trimming |
Hedge Cutting Head | CS1000 | 1000 mm | 3000 r/min | Auxiliary Boom | Side & small-size hedge trimming |
High-branch Cutting Assembly | RDS1500 | 1500 mm | 2800-3000 r/min | Main Boom | Arbor overhanging-branch pruning |
Slope Mowing Module | MT1250 | 1250 mm | 2600-2800 r/min | Main Boom | Slope weed & road-shoulder grass conditioning |
Blades adopt flexible connection structure. High-speed hydraulic motors drive cutter discs at up to 3000 r/min to realize one-pass forming cutting, eliminating repeated back-and-forth finishing operations.
Key kinematic parameters of the equipment: 360° full slewing capability, main boom with 3-section folding plus 1000 mm telescopic stroke, maximum trimming height 6500 mm; auxiliary boom with 2-section folding architecture. - 360° slewing: The boom can switch between left-side and right-side road operations without vehicle U-turn, saving massive time spent on turning, reversing and re-positioning. - Long folding-telescopic stroke: The manipulator directly reaches steep slopes and high branches without frequent vehicle relocation. -210° large folding angle: The boom retracts within vehicle dimension limits during transit for high-efficiency relocation.
When processing the same road segment, conventional single-boom devices require frequent forward, backward and U-turn movements. This truck-mounted vegetation-maintenance workstation completes extensive coverage with boom articulation while the truck travels at low constant speed, greatly lifting effective working mileage per working hour.
The whole system adopts full-hydraulic drive paired with LCD-equipped wireless remote controller:
1. Operators perform remote manipulation within safe zones instead of approaching traffic and slope hazards together with booms, reducing time loss from personnel evacuation and relocation.
2. Hydraulic system delivers stable output with fast response for startup, shutdown and posture adjustment, shortening boom attitude switching time.
3. Stable mechanical performance lowers breakdown frequency and cuts downtime caused by equipment faults.
In practical maintenance projects, total project duration = effective trimming time + vehicle relocation time + equipment commissioning time + safety setup time + fault downtime. This integrated machine compresses the four non-productive time segments simultaneously and finally achieves 60% overall cycle reduction.
A 60% cycle reduction means more than pure speed improvement, and generates cascading benefits:
1. Lower labor expenditure: Large-scale on-site trimming crews are no longer required. Only one truck driver plus one remote-control operator are needed, greatly cutting labor input.
2. Reduced road occupation duration: Highway lane-closure time drops, mitigating traffic congestion risks and bringing prominent social benefits.
3. Better adaptability for narrow maintenance windows. Spring and autumn are peak green-maintenance seasons with limited working windows. Larger mileage of highway green works can be finished within the same time frame.
The FND-HS620 Intelligent Dual-boom Full-hydraulic Multi-purpose Green Maintenance Attachable Unit achieves 60% green-maintenance cycle reduction not merely by raising cutter rotational speed. Its core advantage lies in restructuring conventional serial-sequence operation modes. Four key pillars contribute to schedule optimization: parallel dual-boom operation to eliminate repeated-pass procedures, multi-implement single-host solution to avoid repeated site mobilization, long-stroke boom kinematics to cut vehicle repositioning frequency, and wireless full-hydraulic control to minimize auxiliary time consumption. A large volume of non-value-added hours spent on transit, commissioning and repeated arrivals are eliminated, realizing the upgrading of highway green maintenance working patterns
