Major technical parameters of YTZ5257TQZ40EN

Performance characteristics of YTZ5257TQZ40EN

a. Superior performance and reliable quality:

YTZ5257TQZ40EN road-block removal truck adopts integrated type structure. According to CAE analysis, its working devices have reasonable and matching design and reliable operating performance. Chassis, manufactured by China National Heavy Duty Truck Group Co., Ltd (a famous brand in China), has strong bearing capacity and especially its adaptability is a more competitive advantage as the road-block removal truck has a outstanding feature that is load transfer.

b. High safety:

Adopting dual-circuit braking system and auxiliary engine braking system, the vehicle has strong road adaptability. All of the hydraulic systems of working devices adopt both domestic and foreign brands. Both of luffing cylinder and support arm swing cylinder are equipped with safe and reliable balancing valves, greatly improving the safety performance of the working devices.

c. Reliability and durability:

All moving parts of working devices are equipped with self-lubricating bearings. Especially, the crossarm position of the support arm, which bears larger force and acts frequently, is equipped with enhanced self-lubricating bearing besides retaining the lubricating oil channel. This greatly improves the service life, but also reduces the maintenance frequency.

d. Humanized design:

The thin-type extended support arms of this vehicle, which are equipped mainly for the public traffic vehicles, adopt high-strength steel design, greatly enhancing the strength performance and effectively solving the problem of low chassis of public traffic vehicles. When the arms are used together with reliable L-shaped tire holding tools, the operating performance will become more superior. The operating mechanism is positioned at the rear part of the vehicle and it can be operated at both sides. Moreover, its operating handle is designed with an angle of 60°, which makes the operation more convenient and comfortable. Holding and lifting device adopts modular design and it can be equipped with a support arm which is optional for rescuing trucks.
