9JB Used ZOOMLION Concrete Pump SINOTRUK HOWO 6X4 9M3

Refurbished Concrete Mixer Truck ZOOMLION 9JB on SINOTRUK HOWO 6X4 9M3

Double logarithmic variable pitch helical mixer blade enables higher charging and discharging speed, equal mixing and eliminates segregation. It is also suitable for the transportation of both dry and wet materials.

New generation technology of T-shaped blade. It is made of hard-wearing alloy steel, and thus protects the mixer blades from abrasion, extends the service life of the agitator drum, and enhances mixing performance.

The geometric capacity of the agitator drum is very large and the filling rate is quite low, thus guaranteeing more mixing space. The small inclined angle and lower center of gravity help reduce the possibility of turning over.

Closed loop hydraulic system and constant hydraulic oil temperature controller are used. Key hydraulic accessories are all made by well-known brands with stable and reliable performances.

Pneumatic water supply system. The pressure is provided by the air tank on the chassis with pressure protection devices.

Three-point operation system includes one in the cab to allow control of the agitator drum and two at the rear with operation joystick at each side. Nonmetallic materials are used in joystick system to prolong lifetime and make it easy to operate as well as position accurately.

5%-10% lower fuel consumption via “Automatic Loading Mode Switching” Technology.

Feeding device with long lifespan up to 30,000 m³ due to “material wearing material” technology.

The degree of universality of vulnerable parts is high, and the cost of maintenance is low in the later stage of customers.

WHAT IS CONCRETE PUMP TRUCK

Special concrete transport trucks (in-transit mixers) are made to mix concrete and transport it to the construction site. They can be charged with dry materials and water, with the mixing occurring during transport. They can also be loaded from a "central mix" plant; with this process the material has already been mixed prior to loading. The concrete mixing transport truck maintains the material's liquid state through agitation, or turning of the drum, until delivery. The interior of the drum on a concrete mixing truck is fitted with a spiral blade. In one rotational direction, the concrete is pushed deeper into the drum. This is the direction the drum is rotated while the concrete is being transported to the building site. This is known as "charging" the mixer. When the drum rotates in the other direction, the Archimedes' screw-type arrangement "discharges", or forces the concrete out of the drum. From there it may go onto chutes to guide the viscous concrete directly to the job site. If the truck cannot get close enough to the site to use the chutes, the concrete may be discharged into a concrete pump, connected to a flexible hose, or onto a conveyor belt which can be extended some distance (typically ten or more metres). A pump provides the means to move the material to precise locations, multi-floor buildings, and other distance-prohibitive locations. Buckets suspended from cranes are also used to place the concrete. The drum is traditionally made of steel but on some newer trucks, fibreglass has been used as a weight reduction measure.
