Concrete Machinery - Trailer Concrete Pump (HBT105.21.286RS)

HBT series of diesel engine concrete pump with "S" pipe distribution

Hydraulic system:

Both the main pumping circuit and "S" valve circuit are open-circuit, each is driven by a pump, which makes the two circuits independent to each other. The simplified system, results in a long service life, high reliability and easier troubleshooting.

Proximity switch used to control the direction of the main pumping makes changeover steady and reliable.

Main components of the hydraulic system are supplied by famous brands in the world. The equipped special safety devices, such as relief value, pressure cut-off control, alarming system and auto-reversing etc, promise the system to be more reliable than ever

Driven by the constant pressure pump with an accumulator, the swivel cylinder can get enough moment, and save power at the same time.

All imported seals kits can ensure higher reliability and have a longer life time than ever.

With electrical solenoid or hydraulic direction valve, the switching from high pressure to low pressure becomes easy and quick to operate. There is less hydraulic leakage than the other domestic products.

Electrical system:

Features advanced technology, effortless operation, high reliability

Comes with a Programmable Logic Controller (PLC), which takes the place of many relays, time relays, which not only greatly reduces components but also simplifies wiring in the system, ensures a higher reliability. In combination with PLC, a visual display can indicate the status of inputs and outputs, lead to an easier troubleshooting.

The 90% of the electrical components come from the world-class brands, which guarantees reliability.

Fitting the proximity switches can help to realize automatic direction changeover.

Mechanical system:

During the designing of key parts, such as "S" pipe distribution valve, hopper, software I-DEAS is adopted to realize Finite Element analysis of load distribution, construction rigidity and stress concentration. Owing to its excellent rigidity and process technology, the optimized hopper and "S" valve system can effectively avoid the following phenomena like hopper distortion and breakage of "S" piping valve shaft during high pressure conveying.

By a special design on sealing structure of agitator, hydraulic motors are completely separated from bearing seats, even under the situation of sealing failure, the slurry has no chance to get into motor. High-- torque motors ensure high mixing torque. Thanks to the auto-reversing device and anti-wearing blades, the blockade will never happen even under severe aggregate condition.

The wearing parts, such as the anti-wearing plate and the cutting ring, have a long service life up to 20000m3 under favorable condition.

The distance between the anti-wearing plate and the cutting ring can be automatically adjusted.

Driven system:

Deutz Diesel engines, equipped with electronic accelerator device.

Lubrication system:

The patented central automatic lubrication system comes with a piston grease-pump, features high pressure and reliability, which can realize automatic lubrication of piston. The filters at the outlet and the inlet of oil ports as double protections guarantee the system reliability.

Cooling system:

Compulsory air-cooled heat exchanger keeps the temperature of the hydraulic oil below 60 degree, that ensures the whole hydraulic system works at normal status.

Cleaning device:

Equipped water pump makes the cleaning and maintaining an easy job.
