Trailer Type Mobile Concrete Batching Plant

Why Choose a Trailer Type Mobile Concrete Batching Plant?

A trailer type mobile concrete batching plant is the productivity solution for contractors whose concrete supply must move with the jobsite. Unlike a stationary plant anchored to one location, the trailer type mobile plant integrates aggregate batching, weighing, conveying, mixing, discharging, and automatic control into a single towable chassis — delivering the full process, operation, and maintenance capabilities of a stationary automatic batching plant, but on wheels .

The Howann YHZS series trailer type mobile concrete batching plant is purpose-built for exactly that, covering five production models — YHZS25, YHZS35, YHZS50, YHZS75, and YHZS100 — with theoretical capacities from 25 to 100 cubic meters per hour . Each plant is built on a heavy-duty trailer chassis with towing pin and parking/outrigger legs, powered by a twin-shaft compulsory mixer (JS500 / JS750 / JS1000 / JS1500) and controlled by a PLC automatic control system.

Key Technical Specifications

Parameters constant across the YHZS trailer type range:

• Trailer chassis — complete front & rear axles with towing pin and outrigger (support) legs for parking stability
• No deep foundation required — only compacted hard/level ground needed; commissioning within 1–2 days of arrival
• PLC automatic control — manual, semi-auto, and fully automatic modes; dynamic panel display, data storage & print reports
• Quick-connect utilities — water, air, and electrical lines use rapid couplings; mechanical structures use pin-type quick assembly, no on-site rewiring
• Cement silo options — 50T / 100T / 150T / 200T bolted vertical or low-profile horizontal silos; bag-breaking hopper for bagged cement
• Aggregate bins — 2/3/4-bin configuration, 60–80mm aggregate size, belt conveyor or skip-hoist feeding
• Enclosed eco-options — pulse-jet dust collection and full-plant outer enclosure available for strict environmental standards

How the Trailer Type Mobile Batching Plant Works

The YHZS trailer type mobile concrete batching plant executes a fully automated, continuous production cycle:

1. Site Positioning & Leveling — tow the plant to the designated position, engage the parking brake, extend hydraulic/mechanical outrigger legs to lift axles off the ground, and level the chassis
2. Unfolding & Connections — unfold the aggregate belt conveyor, raise the cement silo, connect power, water, and air lines via quick-coupling fittings; no on-site rewiring required
3. Aggregate Batching — a wheel loader feeds 2–4 aggregate bins; aggregates are individually weighed by load cells and dispatched to the feeding belt conveyor
4. Precision Weighing — cement (from silo via screw conveyor), water (pump + water scale), fly ash, and additives are all weighed independently to ±2% aggregate / ±1% cement, water, fly ash, additive accuracy
5. Twin-Shaft Compulsory Mixing — the JS-series twin-shaft mixer forces shearing, pushing, and tumbling of materials for rapid, uniform blending of dry, semi-dry, and plastic concrete
6. Discharging & Data Logging — concrete discharges at 3.8m height directly into mixer trucks; the PLC system stores and prints production reports for scheduling management

The entire process is orchestrated automatically — one operator in the control room manages the complete workflow from a centralized electrical control panel .

Application Scenarios

The trailer type mobile concrete batching plant is purpose-built for projects where the batching plant must relocate frequently :

• 🛣️ Highway & railway construction — long linear projects that advance continuously; the plant tows forward with the construction front, minimizing transit distance
• 🌉 Bridge construction — dedicated on-site concrete supply for individual bridge projects, eliminating off-site ready-mix dependency
• 💧 Water conservancy & hydropower — remote dam, canal lining, and irrigation works where building a stationary plant is costly; the trailer moves along the canal bank
• 🏗️ Municipal works & urban paving — compact footprint fits tight city spaces; quick relocation between repair sites
• ✈️ Airport runways & ports — large-area paving requiring consistent concrete close to the placement zone
• 🏘️ Remote & rural areas — off-grid sites with onboard water tank; standard 25–35 m³/h units suit local building and temporary jobsites
• 🏭 Small-to-medium precast factories — when production tasks are irregular or the production location needs flexible adjustment
• 🪖 Military & emergency rescue — rapid deployment and high mobility for disaster-relief concrete supply
• Frequently Asked Questions
  Q1: What capacity models are available in the YHZS trailer type series?
  A: The YHZS series offers five models: YHZS25 (25 m³/h, JS500), YHZS35 (35 m³/h, JS750), YHZS50 (50 m³/h, JS1000), YHZS75 (75 m³/h, JS1500), and YHZS100 (100 m³/h, JS2000) . Select based on daily concrete demand, relocation frequency, and available site space.
  Q2: How fast can it be installed and put into production?
  A: Because the plant is pre-wired and pre-plumbed with quick-connect fittings and pin-type assembly, it requires no deep foundation — only level, compacted ground. Setup, wiring, and trial mixing can be completed within 1–2 days, with the first concrete produced shortly after arrival .
  Q3: How does the trailer type differ from the towed type?
  A: The trailer type chassis has complete front and rear axles (like a heavy-duty truck), offering stronger driving stability and load capacity — towing speed up to 50 km/h in some configurations, ideal for long-distance relocation and rough roads. The towed type has only a rear axle with the front on a tractor saddle — lighter, more compact, suited to short-distance moves and tight spaces .
  Q4: What is the weighing accuracy?
  A: The plant delivers ±2% accuracy for aggregates and ±1% for cement, fly ash, water, and additives — meeting high-standard construction requirements .
  Q5: Can it operate without a concrete foundation?
  A: Yes. The trailer type mobile plant requires no poured foundation — only solid, level ground. Outrigger (support) legs stabilize the unit during operation, allowing production to begin within hours of arrival .
  Q6: What mixer and batching system are used?
  A: Each model uses a JS-series twin-shaft compulsory mixer (JS500/JS750/JS1000/JS1500/JS2000) for uniform, rapid mixing, paired with a PLD batching machine (PLD800/1200/1600/2400) and cumulative/individual weighing .
  Q7: What power supply and voltage are required?
  A: Standard configuration operates on 380V/400V, 50Hz, 3-phase power, customizable to local grid requirements. Total power ranges from ~50kW (YHZS25) to ~145kW (YHZS100).
  Q8: What cement silo and aggregate bin options are available?
  A: Cement silos: 50T / 100T / 150T / 200T bolted vertical or low-profile horizontal; bagged cement can use a bag-breaking hopper + screw conveyor. Aggregate bins: 2 / 3 / 4 bins, 60–80mm aggregate size, belt conveyor or skip-hoist feeding .
  Q9: What is the towing speed?
  A: Standard towing speed is 15 km/h (some trailer type configurations up to 40–50 km/h ), with a ~10m turning radius — suitable for highway transport and jobsite maneuvering.
