    Introduction

    38m double bridge pump truck-mounted pump, also known as boom pump, a small type pump, especially used in small towns and rural construction,   is the set of automotive, power system, forced mixing system, pumping system , greatly save labour cost and improve the efficiency of construction. is more mobile and flexible, convenient and efficient.

    Our company is Top world heavy industry independent research and development and relying on its strong production and processing capacity of  manufacturing technology products, has  full function, good performance, and so on.

    Features

    1. According to the characteristics of rural roads choose well-known brands of domestic Dongfeng country IV chassis, the vehicle width 2.5 meters, large-scale lightweight design, vehicle size optimization to smaller meet problem of the narrow path of rural all limit;

    2. The use of flexible comprehensive four sections M type design of the boom, achieve rapid fold and unfold of arm frame.

    3. X X type outrigger is designed with automatic hydraulic system, small occupied area, convenient construction site layout;

    4. The pump ability is 120 cubic meters / hour, can be adjusted freely, free to control the efficiency of construction;

    5. New nation- four engine, up to more than 95% of the ceiling materials, high hydraulic control system and the energy consumption is decreased to the lowest to meet environmental protection.

    6. Core components are used of domestic and international famous brands, high standard, good quality, low failure rate, the system is mature and stable, long life, high ratio of performance .

    7. Circuit adopts integrated wiring harness, few fault points, high reliability, flexible man-machine exchange interface design, makes the operation more simple; remote fault diagnosis function, so that the maintenance is more convenient.
