Operating as an articulated concrete transit mixer, it delivers a 4.5m³ effective volume, 4×4 driving mode, and an 1800 mm unloading height. This setup supports concrete delivery in confined underground infrastructure projects.
Transporting concrete with open tipper trucks often causes material layering and splashing over uneven mine floors. Underground concrete transmixer solves this by rotating the material continuously from batching plant to work site. The JC4.5 replaces manual handling with a controlled, mechanical discharge specifically engineered for roadway surface hardening and tunnel floor construction.
4.5m³ Effective Mixing Volume
The underground concrete transit mixer has a 4.5m³ effective volume, making it suitable for concrete delivery in mine roadways and tunnel construction sites.
Continuous Mixing During Transport
The mixing drum keeps concrete moving during underground transportation, helping reduce layering and early setting during longer transport routes.
4×4 Underground Driving Mode
The 4×4 driving mode supports movement in underground roadways where traction, slope condition, and confined space operation are important.
Controlled Concrete Discharge
The unloading speed is stepless adjustable from 0 to 0.8m³/min, helping operators control concrete discharge during roadway hardening work.
Full Hydraulic Four-Wheel Steering
The full hydraulic four-wheel steering system helps the vehicle turn in underground mine roadways with limited space.
Wet Brake System
The wet brake system supports safer braking performance in underground construction and mining environments.
Mixer Body
The vehicle uses a 4.5m³ mixing drum with a maximum drum speed of 18 r/min.
Drive Mode
The machine adopts 4×4 driving mode for underground roadway transport.
Engine System
The diesel engine system uses a 6CTAA8.3-C215 engine with rated power of 160 kW / 2200 rpm.
Transmission
The gearbox is a DANA R32421-679 power shift gearbox.
Drive System
The drive system adopts hydromechanical transmission and DANA axles.
Brake System
The vehicle uses wet brakes, with hydraulic working braking and spring release.
Steering System
Full hydraulic four-wheel steering supports turning in underground roadway conditions.
Cab
The single metal cab is equipped with operating controls, display instruments, and an adjustable spring seat.

This underground concrete mixer truck is suitable for concrete transport in underground mines, tunnel construction sites, coal mine roadways, mine infrastructure projects, and underground roadway hardening work.
Typical applications include:
In underground construction, open transport methods may lead to concrete splashing, layering, low transport efficiency, and more manual handling. These problems become more obvious when the transport distance is long or the roadway condition is uneven.
An underground concrete transit mixer keeps the concrete rotating during movement. This helps reduce layering, supports controlled discharge, and makes concrete delivery more suitable for roadway hardening and mine construction work.
ZONGDA supports project-based communication for underground concrete mixer truck procurement. Buyers can confirm effective volume, roadway size, unloading height, driving mode, mine environment, concrete transport distance, spare parts plan, shipping arrangement, and after-sales support.
For a quote, please provide mine type, roadway size, concrete transport distance, required mixing volume, unloading conditions, destination country, and any special configuration requirements.
