LM-S Series · Synchronized Rotary
Cab and drum rotate together through 270°. 180° fan discharge, bidirectional driving. Our best-seller in 2.6 / 3.5 / 4.0 m³.
Load, weigh, mix, transport and pour — one 4WD machine replaces a batching plant crew. Synchronized 270° rotation, bidirectional driving, up to 190 m³ a day.
Every Longmai mixer self-loads aggregates, weighs electronically, meters water automatically and pours while driving. Choose the layout that fits your job sites.
Cab and drum rotate together through 270°. 180° fan discharge, bidirectional driving. Our best-seller in 2.6 / 3.5 / 4.0 m³.
One-piece integrated chassis with maximum torsional strength for punishing terrain. 3.5 and 4.5 m³ batch output.
The proven classic layout — fixed cab, drum swings 270°. The favorite for canal and strip pours.
Four-wheel drive with dual high-low range climbs 35–40° grades and crawls over mud, sand and rubble.
Synchronized or independent rotation pours a 180° fan — workers place less, machines position once.
Hydraulic load-cell weighing on the bucket, ±0.5% accuracy, prints a ticket per scoop for true mix control.
Set the seconds, press start — the pump stops itself. Self-priming hydraulic pump fills from any pond or tank.
77–91 kW Yuchai engines standard; Cummins, Weichai Deutz and 6-cylinder options on request.
6 blades, 3 spirals, fast charge and continuous discharge, protected by epoxy primer and baked finish.
Roll-over protected frame, wide 92 cm cab, suspension seat, fan and air-conditioning as standard.
Every truck ships with tool box, filters, grease nipples, hoses and spare kit — plus lifetime parts support.
Self-load sand and gravel with the front bucket; the on-board scale weighs every scoop.
Pour bagged cement from the hopper; timed water system doses automatically.
Drum rotates while driving — mixing completes within 1 km of travel.
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.

Village roads, estate streets and township pavements poured continuously ahead of the truck.

Irrigation channels, drains and reservoirs — set the drum angle, drive forward evenly.

Bridge piers, factory floors, pile caps and building slabs on sites without batch plants.

Where ready-mix cannot arrive in time — mountains, islands, deserts and new development zones.
Our mixers work across Central Asia, Southeast Asia, Africa and South America — markets growing 30–50% year on year.
