1. Product Overview
The Howo 4×2 4m³ Concrete Mixer Truck is a lightweight, compact and high-efficiency concrete mixing and transport vehicle specially designed for small-batch and short-distance concrete delivery. It adopts a 4×2 single-axle layout, including one front steering axle and one rear drive axle, featuring flexible body size and lightweight curb weight, which perfectly solves the construction pain points of large mixer trucks being unable to pass and park in narrow sites.
This mixer truck is built on the mature and reliable Howo light-duty truck chassis. It is professionally equipped with a Weichai 220HP Euro II mechanical pump engine, matched with a Fast 6-speed manual transmission and a standard 10-ton rear drive axle, ensuring stable power output and reliable driving performance. The vehicle is fitted with a fully enclosed hydraulic mixing system, a 300L large-capacity cleaning water tank and a complete feeding and discharging superstructure, realizing integrated functions of concrete feeding, mixing, transportation and discharging.
In terms of body parameters, the overall length of the Howo 4×2 4m³ concrete mixer truck is only 5.8–6.2 meters, with a gross vehicle weight (GVW) of 11000kg and a standard effective mixing capacity of 4 cubic meters. It is a classic light-duty mixing transport equipment, widely used for small-scale engineering concrete transportation and short-distance material delivery.
2. Working Principle
The Howo 4×2 4m³ concrete mixer truck relies on chassis power to drive the fully enclosed hydraulic mixing system. The engine outputs stable power, which is transmitted to the hydraulic motor through the transmission system, driving the mixing drum to rotate at a constant speed. During transportation, the mixing drum keeps rotating clockwise to continuously stir the internal concrete materials, effectively preventing concrete segregation, solidification and quality deterioration during transit.
When feeding and discharging materials, the hydraulic system adjusts the rotating speed and direction of the mixing drum to realize automatic feeding and quantitative discharging. Equipped with an independent 300L cleaning water tank, it supports real-time flushing of the mixing drum, feeding port and discharging tank after operation, ensuring the cleanness of the mixing system and avoiding material residue affecting subsequent mixing quality. The whole working process is fully hydraulically controlled, with stable operation, simple operation and high working efficiency.
3. Daily Application Scenarios
Thanks to its compact body, light weight and flexible passing performance, the Howo 4×2 4m³ concrete mixer truck is widely applicable in various small and medium-sized engineering scenarios that large heavy-duty mixer trucks cannot adapt to. It is mainly used for short-distance and small-batch concrete delivery.
It is very suitable for rural road construction, township infrastructure renovation, residential building construction, rural water conservancy projects, bridge and culvert small-scale reconstruction, and urban community renovation projects. In addition to conventional concrete transportation, the vehicle can be slightly refitted to transport mortar, grout and small aggregate materials, realizing multi-purpose vehicle functions and greatly improving equipment utilization rate for contractors and fleet operators.
4. Comparison With Traditional Models
Traditional heavy-duty three-axle and four-axle large concrete mixer trucks have large body size, heavy self-weight and poor flexibility. They are only suitable for large-scale engineering and main road transportation, and cannot enter narrow rural roads, temporary construction roads and urban narrow construction sites. Moreover, heavy vehicles will cause great pressure on weak pavements and newly paved asphalt roads, easily causing road damage and increasing construction costs.
Compared with heavy large-size mixer trucks, the Howo 4×2 4m³ concrete mixer truck has two core competitive advantages. First, it features light load pressure: the lighter total weight brings smaller pressure on rural unpaved roads, temporary construction access roads and newly paved asphalt surfaces, effectively reducing road damage risks. Second, it has strong multi-scenario adaptability: besides standard concrete transport, it can be simply refitted for mortar, grout and small aggregate haulage, effectively improving vehicle utilization and creating more economic benefits for users. In addition, the compact body is flexible in steering and parking, with low fuel consumption and low operating cost.

6. Operation and Maintenance
6.1 Standard Operation Specifications
Before starting work, check the chassis power system, hydraulic system pressure, mixing drum rotation flexibility and water tank water volume to ensure all components work normally. During material transportation, keep the mixing drum rotating stably to prevent concrete solidification. Do not brake or turn sharply at high speed to avoid material segregation. During discharging, adjust the rotating speed reasonably according to the required discharging volume to ensure uniform and smooth discharging.
6.2 Daily Maintenance Tips
After each operation, use the 300L water tank to thoroughly clean the mixing drum, feeding port and discharging chute to prevent concrete residue from solidifying and affecting subsequent use. Regularly check hydraulic oil level and cleanliness, and replace hydraulic oil and filter elements on schedule to ensure stable hydraulic system operation. Inspect engine, transmission and rear axle lubricating oil regularly, and fasten chassis and mixing system connecting bolts. Standard daily maintenance can effectively reduce failure rate and extend the service life of the mixer truck.
