Brief introduction
This is three wheels stand-on electric tow tractor, powered by battery, front steering as well as driving. Imported AC electric controller is used for a stepless speed regulation, so that it has high efficiency, low noise, simple operation, smooth steering and so on.
Driving System
The special drive unit, product by HELI, realize compact structure, low noise, non-pollution, smooth running. Without carbon brush, AC motor eliminates the need for routine maintenance.
Steering System
Advanced steering technology was adopted to realize smooth, reliable, excellent-following steering.
Braking System
The braking system adopts AC regenerative braking technology which can recover energy to battery for extended use while breaking.
Ramp self-brake makes it more safety.
Controlling System
1）adopt AC controller which is self-protect, maintenance-free and lower noise.
2）Without carbon brush, AC motor eliminates the need for routine maintenance.
With temperature-sensor and speed-sensor, the motor can avoid be damaged abnormally.
3）closed loop control of traveling speed provide an insurance to traveling speed, an excellent-following performance to acceleration and an insurance to control the vehicle while press accelerator during downhill.
4）provide strong power while climbing
5）excellent safety: self-brake can be realized on ramp without operating hand brake
Operating system
Ergonomically designed compartment allows easy operation of all controls and pedals to help reduce operator fatigue.
Other strengths
For 2-3ton type, the battery can be sling vertically or lateral extraction.
For 4.5ton type, the battery is lateral extraction which is easy to replace.
Operator can operate tow hitch without having to leave the vehicle which improve efficiency.
