1. Product Definition

Light trolley, also known as light-duty conveyor trolley, is the core load-bearing component of overhead suspension conveyor systems. It is specially designed for overhead transportation of light-weight small workpieces and matched with monorail or power-and-free overhead assembly lines. The trolley moves along tracks via rolling wheels to realize continuous overhead circulation, serving as essential conveyor accessories for automated production lines in light industry, electronics, food processing and logistics sectors.

Industry Classification Glossary:

Light Trolley: Light load type, standard single trolley load capacity ≤50kg

Heavy Duty Trolley: Heavy-load trolley for auto parts and large hardware workpieces

Power and Free Conveyor Trolley: Accumulating trolley with buffering, stopping and diverting functions

Four-Wheel Trolley: Stable 4-wheel light trolley for easily tipped materials

2. Structure, Materials & Manufacturing Technology

Main Body Materials (Two mainstream options)

Low-alloy steel frame: Cost-effective and wear-resistant, ideal for regular dry workshops

High-strength aluminum alloy frame: Lightweight with low self-weight and anti-rust performance, reducing track and driving load to save energy. Widely adopted in food and electronic clean workshops.

Core Structural Advantages

Compact integrated frame design to minimize overall size while retaining complete loading platform

Precision machined smooth surface to cut running noise and air resistance

Multiple wear-resistant rolling wheels for flexible operation on curved tracks, diverting tracks and climbing tracks

Modular loading platform, compatible with customized hooks, pallets, fixtures and anti-static tooling

3. Transmission & Speed Regulation Working Principle

Two mainstream driving modes for light trolleys, both equipped with frequency conversion control for speed adjustment:

Chain/Belt Driven Trolley A motor matched with a frequency converter adjusts rotation speed to drive the whole line trolleys synchronously via chains or belts with unified speed control, suitable for non-stop continuous production lines.

Independent Electric Driven EMS Monorail Trolley Each trolley is fitted with an individual drive motor with independent speed control, supporting separate start-stop, line splitting and material buffering for highly flexible production. Common adjustable speed range: 0.5–2 m/min for stable low-speed light material transportation.

4. Key Performance Benefits

High Efficiency & Layout Flexibility Low self-weight and small transmission resistance enable smooth fast operation to boost production cycle throughput for mass manufacturing.

Zero Floor Space Occupation Full overhead track layout frees up ground workshop space and simplifies reconstruction of old factories.

Strong Compatibility with Complex Tracks Compact body and universal rolling wheels allow smooth travel through multi-curve, bifurcated and climbing composite tracks to match any production process layout.

Light Load to Cut Infrastructure Costs Aluminum alloy trolleys feature ultra-low dead weight, enabling the use of thin light tracks and low-power drive units to lower equipment and factory renovation investment.

Stable Material Transportation to Avoid Surface Damage Flat loading platform ensures vibration-free operation, preventing scratches and breakage of precision electronic parts and food packaging.

Low Energy Consumption & Easy Maintenance Low power demand for long-term energy savings; modular design allows separate replacement of wheels and frames to simplify repair work.

5. Main Application Industries & Transported Materials

Electronics Industry PCB boards, chips, miniature electronic components and small household appliance shells with anti-static transportation to avoid surface contamination of precision parts from ground friction.

Food & Beverage Industry Bottled drinks, packaged snacks, food boxes and cans. Aluminum alloy and stainless steel contact surfaces meet food hygiene standards for easy cleaning and bacteria inhibition.

Light Manufacturing Garments, small hardware accessories, motorcycle/bicycle plastic spare parts and toy component circulation between production stations.

Logistics Sorting Small e-commerce parcels overhead diversion sorting to realize three-dimensional warehouse sorting and raise processing capacity.

6. Supporting Conveyor System Categories

Standard Monorail Light Suspension System Simple structure with low cost, compatible with straight lines and simple curved tracks without accumulation function, suitable for single continuous assembly lines.

Power and Free Light Suspension System Trolleys support online buffering, automatic splitting and merging without mutual interference, perfect for multi-process production lines with inconsistent working beats.

Independent Electric EMS Monorail Light Trolley Individually driven trolleys with position recognition and cross-line transfer functions, widely used in high-end electronics and new energy component intelligent production lines.
