HAWE and the gearbox of STIEBEL for example.

The distributing system use "S" valves or "Gating" valves as required.

The machines are equipped with safety devices manufactured by International market leaders, such as a pressure valve for the hydraulic pump, balance valves on each boom cylinder, shock-proof maximum pressure valve on rotating head, blocking valve for the outrigger cylinder, and an interlock control in the
electrical control system preventing false operation.

The ZLJ series have a concrete output of 129 m3/h, at a pressure of 12 MPa, a hopper volume of 650 ltr.,
vertical reaches ranging 37m. to 47 m., horizontal reaches from centre of slewing columns ranging from 25m to 33m and slewing ranges of 360°.
A Golden Combination of Heavy Industry and Science
 
     
 
The ZLJ Series of truck mounted concrete pumps are of various types. The whole machines are advanced in technology, have large and wide operation ranges and high in efficiency for delivery. The imported elements used are all from international famous companies such as chassis of Mercedes Benz, Swedish VOLVO, Japanese ISUZU. All of them ensure the high quality of ZLJ Series of truck-mounted concrete pumps.
The boom is made of high resistant alloy steel and is of the state of the art design, providing less weight and greater stress performance. Each placing boom of ÔRÕ type or ÔZÕ type has wide working range, and the rotation transmission, slew rings, electro-hydraulic proportional control valve, balance valve, remote control, etc., are all from international famous companies. All of them ensure high reliability and steadiness and sturdiness of the boom. The fine molten concrete bend has the curve shaped inner thickness, which prolongs its working life.
The pumping hydraulic system is of a double main pumps interflow closed loop system, composed of pumping circuit and distributing circuit, with long-life components, making the whole system more simple and more reliable. ZOOMLION truck mounted concrete pumps are your best choice!
 
International cooperation in science and technology Supported by the famous brands in the world
Outrigger control boards are located on both sides of the turret structure. All the motion of the outriggers is controlled through distributor levers and locked by hydraulic locks. The level indicator near the distributor shows the inclination of the whole machine. Near the position of closed outriggers is the spring lock with can fix the outriggers conveniently and safely when the truck is travelling.
The slewing mechanism on the placing boom is equipped with stroke limiting valve and rotation control valve in order to keep the boom steady in operation.
The standard coupling of the delivery pipeline on the boom may be used as rotary joint or common joint. The same sized bend tube and straight tube ensures the best changeability.
