Why Longmai
Engineered where transit mixers cannot go
Full-time 4WD
Four-wheel drive with dual high-low range climbs 35–40° grades and crawls over mud, sand and rubble.
270° Drum Swing
Synchronized or independent rotation pours a 180° fan — workers place less, machines position once.
Electronic Weighing
Hydraulic load-cell weighing on the bucket, ±0.5% accuracy, prints a ticket per scoop for true mix control.
Auto Water Metering
Set the seconds, press start — the pump stops itself. Self-priming hydraulic pump fills from any pond or tank.
Yuchai Turbo Power
77–91 kW Yuchai engines standard; Cummins, Weichai Deutz and 6-cylinder options on request.
Manganese Drum
6 blades, 3 spirals, fast charge and continuous discharge, protected by epoxy primer and baked finish.
ROPS Comfort Cab
Roll-over protected frame, wide 92 cm cab, suspension seat, fan and air-conditioning as standard.
Parts On Board
Every truck ships with tool box, filters, grease nipples, hoses and spare kit — plus lifetime parts support.
How It Works
One operator. Full concrete cycle.
Load & Weigh
Self-load sand and gravel with the front bucket; the on-board scale weighs every scoop.
Add Cement & Water
Pour bagged cement from the hopper; timed water system doses automatically.
Mix on the Move
Drum rotates while driving — mixing completes within 1 km of travel.
Pour Precisely
Swing the drum up to 270° and pour a 180° fan exactly where the crew needs it.
A full cycle takes 10–15 minutes — 3 to 5 batches per hour, 80 to 190 m³ per 10-hour day depending on model.
Applications
Built for the jobs others can’t reach
Rural & Town Roads
Village roads, estate streets and township pavements poured continuously ahead of the truck.
Canals & Waterways
Irrigation channels, drains and reservoirs — set the drum angle, drive forward evenly.
Foundations & Piles
Bridge piers, factory floors, pile caps and building slabs on sites without batch plants.
Off-Grid Sites
Where ready-mix cannot arrive in time — mountains, islands, deserts and new development zones.
