Frequently asked questions

Match the machine to your daily concrete volume:

Model	Output per 10-hour day
LM-S2600 (2.6 m³)	80–100 m³
LM-S3500 / LM-F3500 (3.5 m³)	110–140 m³
LM-S4000 (4.0 m³)	120–160 m³
LM-A4500 (4.5 m³)	150–190 m³

Example: a 10 km road, 6 m wide, 20 cm thick needs 12,000 m³. Two LM-S4000 machines pouring 300 m³/day finish in about 40 days. Tell us your project and we will size the fleet.

One full cycle takes 10–15 minutes depending on operator skill: 2–3 min self-loading, 4 min timed water filling, 1–2 min mixing, then discharge — and the drum keeps mixing while you drive up to 1 km. That is 3–5 batches per hour.

A quick-reference recipe is pre-set per model — e.g. the 3.5 m³ machine takes 7 scoops (4 gravel + 3 sand), 22 bags of cement and 4 min 20 s of water for C25 concrete. Optionally, the electronic hydraulic weighing system weighs every scoop to ±0.5% and prints a ticket, so quality is verified batch by batch.

Two stages: first the hydraulic self-priming pump sucks water from any pond, tank or tanker into the on-board tank; then set the timer on the dash and the system meters water automatically and shuts off — two batches per fill on most models.

Yuchai turbocharged diesel is standard (4102 on 2.6 m³, 4105 on 3.5 m³, 4108 on 4.0/4.5 m³). Optional: Cummins 4BTA3.9-C125-II, Yuchai 6-cylinder YC6J125Z-T20, Yuchai Euro-5, or Weichai Deutz WP4G130E22.

Every unit ships with: cement hopper, discharge extension chute, hydraulic washer gun and hose, water suction pipe, tool box, oil/fuel filters, grease nipples, wheel bolts, fuses and other consumables — the full start-up kit. Spare parts support continues for the life of the machine.

8 gears: 4 forward / 4 reverse with dual high-low range. Work in low gear at 10–15 km/h (mixing while driving). On empty repositioning runs, high gear allows 30–45 km/h depending on model.

Rural and township roads, irrigation canals, slope and dam protection, factory and workshop floors, bridge piers and pile caps, building slabs, stabilized base layers, pervious concrete, plantation estate roads — anywhere ready-mix cannot arrive on time.

Production is 15–20 working days after the deposit and the configuration are confirmed. Loading one 40'HQ takes two to three days, then the sea leg from Qingdao — typically 22–35 days to the Maghreb or West Africa depending on routing and transhipment. We photograph the loading sequence before the container is sealed and send it with the shipping documents.

The engine is covered for 6 months and hydraulic components for 12 months, counted from commissioning. Wear parts, consumables and damage from misuse are excluded. Parts replaced under warranty ship free within China; international freight and local labour are at the buyer's cost.

Commercial invoice, packing list, bill of lading, certificate of origin and the battery transport test certificate for the lead-acid battery. We can coordinate with your customs broker. Tell us your HS code and destination port and we will confirm the document set before you order.

Machines entering Vietnam are subject to the national technical regulation QCVN 19:2024/BTNMT on industrial emissions, which took effect in July 2025. We supply an emission conformity file with each unit and can quote engine options that already meet the standard. Buyers normally also need a quality inspection (đăng kiểm) of the vehicle for road registration — we provide the technical dossier needed for that process.

Yes — we supply trading companies and dealers worldwide with marketing materials, colour and specification customisation and priority parts dispatch. On delivery you get the full spare-parts catalogue by assembly, a complete start-up kit, a pre-shipment running test video and a live video factory visit on request.
