Front cutting knife

Main Frame Structure

• Made of wear-resistant high-strength special steel, adapting to complex forest conditions, for long-term use in extreme environments (-40°C ~ 100°C).

• Integrated welding, quenching and tempering heat treatment, and non-destructive flaw detection ensure no deformation under long-term heavy loads.

• Engineering CAE simulation and lightweight design balance operational flexibility and equipment protection.

Operation Handle 

• Multi-function design with one-touch activation; a single hand can complete the entire harvesting process.

• Customizable key logic for quick access to frequently used functions, for faster learning.

• Single handle integrates multiple actions: grabbing, delimbing, cutting, rotating, tilting, proportional control, etc.

Measurement System

• One-piece cast construction eliminates assembly welds; durable and non-deforming despite high cost.

• Intelligent precise diameter measurement using high-precision pulse sensors, ensuring accurate dimensions for precise operational control.

• Stable structure, fast response, and low error improve harvesting standardization and yield rates.

Electrical System 

• Self-developed CAN3.0 control system collects machine fault and operational data, positioning, feedback, supports multi-language, and visualizes pricing, operation, maintenance, calibration, work area, and statistical reports.

• Win10/Win11 compatible display supports Beidou, GPS, Starlink, breaking the domestic technical barrier.

• Intuitive touchscreen supports third-party apps, making it easy to learn and use.

• Supports remote after-sales, fault self-check, and protection functions to reduce downtime risk.

• Imported CAN communication controller chip with anti-interference and stable performance.

Hydraulic System 

• Self-developed: large flow, stable pressure, high-precision flow control, fast directional response, high grabbing/cutting efficiency.

• High-precision proportional valves, high flow, high speed, high pressure, PWM intelligent control for coordinated and powerful movements.

• Feed system: high pressure, high speed, large torque, speed 5m/s.

• Hydraulic cylinders use wear-resistant, high-pressure, high-speed seals for low oil leakage and long pressure retention.

Delimbing Knife

• One-piece cast construction for strength and durability; sharp blades ensure clean delimbing without damaging the trunk.

• Clamping mechanism designed via 3D simulation adapts to various tree species for better contact with logs.

Cutting System 

• German import saw motor: one-touch intelligent cutting + automatic length setting, boosting single-shift output by up to 40%.

• Saw box with built-in automatic lubrication/cooling channel for continuous temperature reduction, reducing wear and extending saw chain/guide bar life; side guards + anti-kickback structure improve safety.

• Cutting assembly (chain + bar + tensioner): automatic chain tensioner maintains optimal tension without manual adjustment, preventing chain loss or breakage; high-strength alloy wear-resistant guide bars for long life, low energy consumption, and failure rates.

Feed Rollers

• 3 rollers / 4 motors (top 2 + bottom 1): bottom support + top compression creates an enveloping grip, increasing traction by over 40% compared to flat wheels. Stable feeding even on steep, slippery, or curved logs without slipping, dropping logs, or damaging bark.

• Adaptive intelligent feed maximizes efficiency and yield with even power distribution and straight feeding.

• Profiled (convex arc + wear-resistant stud teeth) non-flat design for increased contact area and grip.
