Green maintenance work for expressways and provincial highways includes trimming of median barrier hedges, roadside shrubs, slope weeds and overhanging branches. Traditional handheld trimming tools require heavy manual labor with low working speed, and bring significant safety risks for workers operating alongside live traffic. The FND‑HS620 intelligent dual‑arm full‑hydraulic vegetation trimmer, also known as truck‑mounted dual‑boom roadside pruning unit or multi‑arm highway green‑care machine, is a vehicle‑carried green‑maintenance solution. Equipped with dual working booms and full‑hydraulic structure together with wireless remote‑control system, it can conduct plane, side and inclined‑surface trimming simultaneously. It handles hedges, shrubs, high branches and slope mowing in one unit, cutting manual labor while greatly improving working efficiency and site safety for routine highway vegetation maintenance.
1. Existing Shortcomings Of Conventional Roadside Green Trimming
Roadside greenery presents complex working conditions, with narrow median strips, inclined slopes and overhead tree branches. Traditional operation patterns show multiple obvious drawbacks.
First of all, small handheld trimming devices rely heavily on manpower. Operators suffer high physical fatigue after long‑time work, and daily coverage is limited. Large‑scale green projects along long‑distance expressways demand numerous maintenance staff, pushing up overall labor costs.
Secondly, highways remain open to moving traffic. When workers trim vegetation at close range beside passing vehicles, they face considerable risk of traffic‑related accidents.
Furthermore, single‑purpose machines can only handle flat hedge cutting. Separate equipment has to be deployed for slope clearing and high‑branch pruning. Frequent machine transfer causes constant work interruptions and poor continuity. Single‑boom trimmers cannot perform flat‑surface and side‑surface cutting at the same time. Operators must repeatedly adjust machine positions for each section, further slowing down overall progress.
2. Overview Of FND‑HS620 Dual‑Arm Greenery Trimming Unit
The FND‑HS620 intelligent dual‑arm full‑hydraulic vegetation trimmer is a truck‑mounted multi‑purpose roadside pruning unit. It is installed directly onto flat‑bed cargo trucks. Powered by a Yuchai diesel engine, every movement is driven by full‑hydraulic circuits. Two independent working booms are fitted, supporting 360‑degree slewing, large‑angle folding and boom extension. A wireless remote controller with LCD display allows operators to manage all machine movements away from rotating cutting heads.
The main boom adopts three‑section folding plus one telescopic segment, delivering maximum trimming height of 6500 mm. The secondary boom features two‑section folding structure. It cooperates with the main boom to finish top‑surface and side‑surface trimming for highway median strips. Various working attachments can be swapped quickly for hedges, high branches and slope weeds. One single machine covers diverse vegetation‑maintenance requirements.

3. Core Functions And Product Advantages
1. Dual‑Boom Simultaneous Operation For Higher Productivity
Main and secondary booms work independently. When servicing highway medians, the unit completes top‑surface trimming and vertical‑side trimming in one single vehicle pass without repeated forward‑reverse movements. Along road shoulders, the main boom reaches high overhanging branches while the secondary boom trims lower shrubs, drastically shortening working hours for long‑distance roadside vegetation projects.
2. Full‑Hydraulic Drive With Flexible Boom Adjustment
Equipped with fully‑automatic three‑section folding and telescopic boom assembly, the machine supports 360‑degree rotation, 210‑degree folding and 1000 mm telescopic travel. Cutting heads can be freely re‑positioned for median barriers, vertical roadside zones and inclined slopes. Hydraulic transmission delivers stable movements with low operational noise.
3. Quick‑Change Specialized Working Attachments
Dedicated cutting assemblies are provided for hedges, high branches and slope grass. Blades use flexible connection design; cutter head rotation speed can reach up to 3000 rpm. Operators swap attachments quickly on‑site. A single machine performs hedge shaping, high‑branch cutting and slope weed removal, eliminating costs caused by deploying multiple separate machines.
4. Wireless Remote‑Control Improves Operator Safety
The wireless LCD remote‑control system lets operators stand in safe zones far from traffic and fast‑spinning cutters. Personnel no longer need to stay inside high‑risk roadside work zones, effectively reducing safety hazards during highway maintenance while retaining high operational flexibility.
5. Purpose‑Built Design For Highway Vegetation Maintenance
Developed specifically for roadside green‑care scenarios, this compact truck‑mounted unit can be transported rapidly between different maintenance sections. It fits routine vegetation‑service tasks for expressways and provincial‑grade highways.
4. Typical Application Scenarios
1. Highway Median Strip Trimming: Main‑secondary boom combination trims both top and side faces of median hedges, representing the most frequent working scenario for expressway maintenance teams.
2. Roadside Shrub And High‑Branch Pruning: The main boom extends up to 6.5 meters for overhead tree branches, while the secondary boom tidies lower‑level roadside shrubs.
3. Highway Slope Vegetation Clearing: Install slope‑mowing attachment, adjust boom inclination angle to cut weeds and wild shrubs on road embankment slopes.
4. Road‑Shoulder Platform Green Care: Adjust boom posture to complete flat‑surface shaping for hedges and lawns on road‑shoulder platforms.
5. Operation And Maintenance Notes
Before starting work, verify stable wireless‑remote signal, confirm hydraulic‑system pressure stays within rated range and inspect blade fastening conditions. Avoid hitting stones or rigid obstacles during operation to prevent blade damage. After each working shift, clear leaf debris from cutter assemblies, inspect hydraulic hoses for leakage, replace hydraulic oil on schedule and carry out regular engine maintenance to secure long‑term reliable machine performance.
