Description

The HONGDA concretis independently developed by SHANDONG HONGDA GROUP on the basis of absorbing advanced domestic and foreign technologies. The product is mainly used for mixing and transporting concrete mixture between long distances.
It can effectively delay pre-hardening, avoid stratification and eduction, and ensure construction quality and speed. The HONGDA series of truck-mounted concrete mixers can be divided into various models, such as 6m³,8m³,9m³,*0m³,*2m³,*4m³ and *6m³,which can be matched with any special domestic and foreign chassis according to customers’ choices.
The driving system of the mixing drum adopts the closed-type hydraulic system pump, motor and reducer which are imported from theUS andGermanywith original packaging.
The necessary hydraulic accessories such as the oil tank, radiator, filter and rubber hose connector are all imported parts. All this ensures the hydraulic system a long service life.
The mixing drum body and the double-logarithmic variation-parameter helical vanes are all made of fine-grain abrasion-resistant steel plates specially used for the B**0JJ mixing drum made by Shanghai Baosteel Company.
All the quick-wearing parts like the feed hopper and discharge hopper chutes which have much contact with concrete are also armored with abrasion-resistant steel plates, which correspondingly ensure the product a rather long service life. Not only are many mixing arms designed in the mixing drum, but also square and round holes are scientifically arranged in the mixing vanes.
This design has realized the actual three-dimensional mixing of concrete in the mixing drum, with discharge surplus close to zero and concrete eduction greatly avoided. The moveable discharge chute can be locked at 4 different positions for discharge operations in different directions.
The upper part of the truck adopts the shot blasting and baking finish technology. While elegant and pleasing in design, the truck-mounted mixer shows many advantages such as stable and reliable slewing, speedy discharge, low surplus rate, handy operation and long service life.
