3. Quotation
 
Based on high quality, DAWIN Machinery pursues optimum cost performance, which is one of the symbols of the concrete pumps. In other words, that is the favorable price! 
 
A favorable price does not mean a high price because a high price is abhorrent to the optimum cost performance put forward by DAWIN Machinery. A favorable price doest not mean a low price because a low price is insufficient to support the high quality and timely after-sales service. 
 
What we show you is that after you know the quality and after-sales service of JH concrete pumps, you will find that our pricing is favorable and the cost performance is optimum.
 
If you don't believe, just have a try!
 
4. Introduction
QTHB Series Trailer Concrete Pump Boom is a popular small model with max. placing height 21, 25, 28 and 32m researched and developed by our company after our HBT series trailer-mounted concrete pumps, HBC truck mounted concrete pump boom, HGY series hydraulic concrete placing booms and JH series truck concrete pump boom. 
Trailer Concrete Pump Boom is combined with high reliability, economy, safety and durability. It has reasonable collocations for power system, control system, hydraulic system and pumping system. With the characteristics of flexible foldable arms, little space occupying support legs, easily movable advantages, equipped with H/L pressure switch, high outlet pressure, the whole concrete pump boom is more flexible, reliable, stable and safe. It is the top-choice concrete equipment widely used in tunnel, airport, seaport, high-speed rail site, beam field, bridge construction projects and so on. 
4.1 Advantages
QTHB Series Trailer Concrete Pump Boom combines the functions of pump and boom in one machine, which achieve the delivery and pouring of concrete to the building. It is easy to operate QTHB in a low cost of use.
QTHB can be operated by one operator and the movement of boom can be controlled in use of wireless remote control which may save labor and easy to operate.
Optimized arc-shaped hopper makes a higher inhalation rate.
Boom is slewed in tower rotation by hydraulic drive with 360°.
Standard configuration with wireless remote control makes the operating more easy and convenient.
Main electronic components are world-famous brands.
 
4.2Jib structure system
It is based on the finite element analysis, dynamic analysis and test, and the accurate data support.
4.2.1High strength low alloy steel plate, all materials and welding line by 100% non-destructive technology ensure the jib structure reasonable and highly reliable.
4.2.2 "R" or "M" type arms with speed stepless adjustment, pressure compensation and load sensing proportion control system ensure the arm running freely and excellent operating performance.
