38m double bridge pump truck-mounted mixing pump, also known as boom pump, a small type pump, especially used in small towns and rural market development,  combined mixing pumping in one, is the set of automotive, power system, forced mixing system, pumping system and fabrics arm frame in one of the micro mobile type concrete mixing station, greatly save labour cost and improve the efficiency of construction. is more mobile and flexible, convenient and efficientl.

Our company is Topworld heavy industry independent research and development and relying on its strong production and processing capacity of lean manufacturing technology products, has a high profile, full function, good performance, and so on the comprehensive advantages of exquisitely.


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 60 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 to price.

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 repair, maintenance is more convenient.

8. Adopt domestic famous brand 500 compulsory mixer, mixing concrete, good quality.
