| Performance | |
| Hill Start Assist | Satisfies operating conditions with a slope angle of 55° (50° triggers equipment alarm: horn + warning light; 55° activates automatic shutdown for excessive angle protection (exceeding 55°), preventing overturning. Angle sensors are added to detect terrain changes during operation. Should the angle exceed the machine’s limit, an automatic alarm activates to prevent misoperation and overturning.) |
| Continuously Variable Transmission Control (0 to 100%) | Operating speed Forward/Reverse 0–4 km/h Transfer speed Forward/Reverse 0–9 km/h |
| Parking | Remote parking switch ensures the equipment remains securely stationary. The parking knob enables the machine to be parked on site, functioning as an electronic handbrake. This effectively safeguards safety, preventing rollaway incidents and accidents caused by misoperation. |
| Steering | Skid steering, enabling turning on the spot |
| Hill Descent Control | Yes (When operating on slopes, excessive angles may cause the machine to tilt due to its own weight. Installing an inclination sensor and programming the system to activate braking and corrective steering is recommended). |
| Cruise Control | Yes (One-click cancellation) |
| Safety | |
| Emergency stop | One-touch stop |
| Excessive tilt angle | Alarm (horn + warning light), automatic shutdown |
| Headlights | LED |
| Signal loss | Automatic parking |
| Other | Hydraulic system, abnormal oil pressure, automatic shutdown |

| Brief Overview of Functional Advantages: | |
| 1) Custom-designed integrated oil-water cooling system, ensuring effective heat dissipation under any permissible machine operating conditions; 2) Independently developed bidirectional fan system, supporting periodic cleaning of cooler covers and forced cleaning via a miniature air compressor. Incorporates reversible fan blades, controllable by remote or programmed timers, enabling airflow from both sides of the radiator. This simultaneously cools the engine and facilitates dust removal; 3) All operations are remotely controllable via the remote control unit. Every function of this machine is remotely operated, featuring dual-layer safety measures: the machine itself has an emergency stop button, and the programme includes an emergency shutdown function (the machine automatically shuts down if the receiver fails to receive a signal within 2 seconds); 4) Supports on-the-spot turning capability. Dual joystick operation enables turning on the spot and fine-tuning turns during travel; 5) Attachment changeover time <10 minutes (pure operation time). Each attachment can be swiftly exchanged using imported quick-release couplings, significantly extending service life. 6) Equipment maintenance monitoring: Real-time surveillance of water temperature, oil temperature, oil level, RPM, and blockages ensures optimal operational status. The receiver display provides live monitoring of the entire machine’s condition, with sensors detecting whether the machine is functioning normally. |
