The Haomei HDT5120THB truck-mounted concrete pump with boom is
developed by Haomei Group on the basis of drawing on advanced
domestic and foreign experience and using advanced modern computer
simulation techniques to systematically analyze the effect of
changes in various parameters like stress, displacement and natural
frequency on the boom’s fatigue life.
Meantime, Haomei Group optimized the design of the hydraulic
system, adopted the latest free fluid technique and greatly
lessened the impact of pumping commutation on the distributing
boom. In the boom structure optimization and the hydraulic system
design, Haomei Group has obtained many patents. The consummate
control of product quality, perfect techniques of product
manufacturing and strict procedures of quality inspection make the
Haomei pump truck a leading product in China and an advanced
product in the world.
All the steel plates for the boom system are high-strength cold
rolling steel plates made by the Swedish company SSAB. The yield
strength of the plates exceeds 900Mpa, which ensures that the boom
system has high strength and light weight. The boom system’s
distributing pipe, landing legs, oil tank and soon have all
received 100% stress-removing treatment after welding.
Every welding seam has passed the 100% undamaged and crack
detection or X-ray radial check to avoid any tiny defects and to
make the machine more enduring.
Main features of HDT5120THB truck-mounted concrete pump
1. Adopting the special chassis for Dongfeng brand heavy-duty
truck, elegant and unique appearance, comfortable to drive, strong
in horsepower, low in oil consumption, reliable and durable in
2. The power system which adopts the world-famous 6-cylinder
DACHAI-DETUZ diesel engine has stable and reliable performance.
Equipped with the auto throttle, the engine shows an economical
efficiency of fuel consumption.
3. The hydraulic system adopts the German REXROTH oil pump and the
American VICKERS control valve, which match perfectly and have
4. The main electric components of the PLC computer control system
are brand products made by SIEMENS, LG, SCHNEIDER and so on.
5. All operations can be carried out by short-distance control and
wired remote control. There are two separate operating devices,
ensure the reliability and safety of the equipment.
6. The S-shaped reversing valves, hard alloy eyeglass plates and
cutting rings, rubber springs which can automatically compensate
the clearances between end faces, all ensure a proper sealing
7. The mixer can rotate forward or backward and rotating speed can
be regulated so that the problem of aggregate blocking can be
settled in time.
8. The big-diameter conveying cylinder has a strong suction ability
and can afford large pumping flow. The pumping capacity can be
regulated through the stepless control device to get different
9. The equipment has such functions as positive pumping, reversing
pumping and inching. The conveying pipe is easy to clean and the
concrete piston is very convenient to replace.
10. The high-pressure cleaning system makes vehicle cleaning simple
11. The automatic lubrication of the hopper and the concrete
cylinder makes the pumping work smooth and easy.
12. The sealing parts of the main oil cylinder are made by PARKER
Company of the US, and the inside of the concrete cylinder is
covered with a thickened chromium coat, which ensures that 20,000 m
of concrete can be successfully pumped without any problems.
