Equipment description and main structure of heavy-duty vehicle suspension conveying system
1. Equipment overview
The heavy-duty vehicle suspension conveying system is designed for the production and assembly of large-size, high-weight (1-20 tons) workpieces such as heavy trucks, construction machinery, and large buses. Its core function is high-load, high-stability conveying, supporting continuous operation and precise positioning, and adapting to harsh working conditions such as welding, painting, and assembly.
2. System advantages
High load capacity: Suitable for heavy workpieces over 10 tons, with stability far exceeding that of light conveying systems.
Precise control: PLC+servo positioning, with a repeatability of ±1mm (assembly line requirements).
Safety redundancy: Dual-circuit braking + mechanical limit to ensure that the carrier is locked in the event of a sudden power outage.
Energy saving and environmental protection: Energy feedback inverter, energy consumption reduced by 15%-20%.
3. Typical application scenarios
Heavy-duty truck assembly line: frame conveying, cab assembly.
Engineering machinery welding line: excavator boom, crane turntable
conveying.
Coach painting line: body electrophoresis, paint spraying and
drying process.
4. Selection recommendations
Working parameters | Recommended configuration |
Load ≤ 5 tons | Single drive station + standard chain (pitch 150mm) |
Load 5-15 tons | Double drive station + reinforced chain (pitch 200mm) |
High temperature environment | High temperature resistant chain (ceramic coating) + water-cooled track |
1. Main structural components
1. Heavy-duty track system
Material: high-strength carbon steel (Q345B or above) or hot-dip
galvanized steel, bending strength ≥500MPa.
Layout: multi-level support frame, can withstand dynamic load of
more than 10 tons, span ≤6m (anti-droop).
Branch design: hydraulic/electric turnout switching, supporting
multi-station parallel operation.
2. Power and transmission unit
Drive device: high-power variable frequency motor (15-75kW) +
planetary gear reducer, stable torque output.
Traction chain: reinforced double hinge chain, breaking strength
≥150kN, temperature range -30℃~150℃.
Tensioning mechanism: hydraulic automatic compensation system,
real-time adjustment of chain tightness.
Suspension carrier and fixture
Carrier structure: customized steel structure frame +
impact-resistant bearing, suitable for special-shaped workpieces
such as frame and cab.
Clamp type: pneumatic clamping/electromagnetic adsorption,
positioning accuracy ±2mm.
3. Safety and control system Emergency stop and overload
protection: full-line emergency stop button + torque limiter,
automatically cut off power when overloaded.
Intelligent control unit: PLC + industrial computer, integrated
RFID/barcode recognition, to achieve full-process traceability of
workpieces.
Anti-sway device: track lateral limit wheel + damper to reduce
carrier shaking (amplitude ≤5mm).
4. Auxiliary system Lubrication module: automatic drip
lubrication to reduce chain wear.
Dust removal and cooling: high-pressure air knife (painting line)
or water cooling cycle (welding line).
