• Automatic sound warning for travel.
Multi-function comfortable luxury cab environment
• The spacious and multi-function cab designed according to ergonomics enhances comfort for operator.
• The luxury suspension seat can be regulated to provide optimal comfort for driver.
• The mounting seat of cab adopts silicone oil & rubber material, it can both reduce the vibration and noise in the cab and greatly reduce the driver's fatigue, tremendously enhancing work efficiency.
• The high-power air-conditioner and multi-hole circulating system enhance the refrigeration and heating capacity, to ensure comfortable temperature in the cab.
• The cab has protective railings, so the operator is safer and more comfortable.
Convenient maintenance system
• Three side doors can be opened, so that each maintenance point can be accessible when routine inspection and maintenance are performed.
• The label of maintenance point is clear and simple, convenient for operation.
• Electrical components are all arranged in the cab and the electrical control box for easy maintenance.
• Walkways are increased on both sides of the platform, avoiding the trouble from ground maintenance and making maintenance easier.
• The engine hood is opened a small door for the part of the engine needing maintenance, so that maintenance work becomes very convenient.
