Depth Analysis of Core Performance Metrics in Electric Trolley Power-assist System

Load Capacity

1. The Impact of Load Capacity 

Load capacity directly determines the applicable scope and operational efficiency of electric trolley power-assist systems, influencing the system’s motor power, battery life, and overall structural design.

• When the trolley is required to carry heavier loads, the motor must generate greater torque to overcome static and dynamic friction, enabling it to start, accelerate, and maintain stable travel.
• Prolonged use under heavy loads can cause the battery’s charge-discharge cycles to reach their limit prematurely, necessitating frequent battery replacements and increasing operational costs.
• In terms of overall structural design, the load capacity setting determines the selection and strength design of critical components, including the trolley frame, wheels, and transmission mechanism.

2. Load Capacity in Different Application Scenarios

Practical requirements for load capacity vary greatly across different industries, and understanding these differences is essential for selecting the right power-assist system.

• In industrial environments, facilities often depend on high-capacity trolleys designed to transport heavy machinery, bulk materials, or large equipment across long distances.
• Agricultural operations usually work within medium capacity ranges, but the demand for stability and consistent performance on uneven or soft ground is equally significant.
• In contrast, medical settings rarely involve heavy loads, yet they require electric dollies’ power-assist systems that deliver smooth, precise movement to protect delicate instruments and ensure safe handling.

3. Consequences of Exceeding Load Capacity

Exceeding the rated load capacity places excessive strain on every part of the power-assist system, leading to serious consequences.

• Motors forced to operate beyond their design limits are prone to overheating and premature failure, while batteries discharge at a faster rate, reducing overall endurance and increasing downtime.  
• Structural components, from frames to support joints, may also weaken under the extra stress, raising the risk of unexpected breakdowns.
• In addition to mechanical issues, handling becomes more difficult, with longer stopping distances, reduced maneuverability, and a greater chance of accidents.

Adhering to the manufacturer’s specified limits is not only a matter of maintaining equipment reliability but also a critical step in ensuring operator safety and long-term performance.

Speed 

1. The Importance of Speed Control

The speed control effect is directly related to work efficiency and operation safety of an electric trolley power driving system. A trolley that operates at very low speeds causes delays in workflows and reduces overall productivity, while excessive speed in busy or restricted environments increases the likelihood of collisions or accidents. The ability to regulate speed appropriately ensures that goods are moved quickly where efficiency is needed, yet handled cautiously in spaces where safety and stability are important.

2. Technical Considerations for Achieving Variable Speed

To achieve variable speed functionality in electric drive kits, it’s important to carefully consider both the controller technology and the motor type.

A high-quality controller should provide precise current control, voltage regulation, and speed feedback. Brushless DC motors are highly regarded for their efficiency, stable torque, and long service life. Combined with a modern electronic controller, they offer smooth acceleration, responsive braking, and precise speed control under various load conditions. This integration improves operator control and reduces component strain, allowing the trolley to adapt effectively to various working environments.

3. Speed Requirements in Diverse Scenarios

The speed requirements for electric power-assist systems vary significantly across different scenarios.

• In warehouses, a speed of 8-15 km/h is efficient for transporting lightweight, non-fragile items like cardboard-boxed household goods in spacious areas with few people. However, in narrow aisles with dense shelving or fragile items like glassware, lower speeds are needed to avoid collisions and damage.
• In industrial workshops, higher speeds can be used when the layout is sparse, the floor is even, and heavy components are being moved. Conversely, if there are many machines, pipelines, or slippery floors, lower speeds are essential to prevent collisions and loss of control.

Gradient Capability

1. The Role of Motor Torque and Gear Ratios

Gradient capability reflects a power driving system’s ability to operate on slopes and uneven ground, and it is largely defined by motor torque and gear ratios. Torque provides the force needed to move loads uphill, while gear ratios control how efficiently that force is delivered. A system designed with sufficient torque and well-matched gearing can climb inclines steadily without placing excessive strain on the motor or draining the battery too quickly.

2. Gradient Capability in Different Terrains

Matching gradient capability to the terrain is essential for consistent performance and long-term durability. 

• On flat indoor floors, gradient capability plays a minimal role, as movement requires little force.
• Agricultural fields demand a stronger capability to manage mild slopes and irregular surfaces while keeping loads stable.
• Construction sites present the greatest challenge, where steep inclines and heavy materials require robust torque and durable gearing to ensure safe and reliable operation. 

Range and Endurance

1. The Significance of Range and Endurance

Range and endurance describe how long an electric power-assist system can operate before the battery needs recharging. They have a direct effect on efficiency because a system with good endurance can operate through a full shift without interruption. If the range is too limited, frequent charging breaks slow down tasks and reduce overall productivity.

2. Factors Affecting Range and Endurance

• The battery capacity sets the overall operating limit, with larger batteries offering longer use.
• The load weight has a major impact, as heavier loads require more energy and shorten the runtime.
• The operating speed also plays a role, since higher speeds consume power more quickly than controlled and moderate movement.
• The terrain condition is another variable. Smooth indoor floors minimize energy use, while slopes or rough surfaces demand more power and reduce overall endurance.

When these factors are properly balanced, the trolley power drive system delivers consistent operation without unnecessary downtime.

Noise Levels

Noise level is a key factor in evaluating the quality of an electric trolley power-assist system. A low-noise system creates a more comfortable working environment by reducing stress and fatigue for operators and those nearby. In places such as hospitals, offices, or hotels, quiet operation is especially important to avoid disturbance and maintain a calm atmosphere.

Controlling noise is also a matter of compliance. Many industries are subject to workplace regulations that set acceptable noise limits to protect employee health and safety. Equipment that exceeds these thresholds can result in penalties or operational restrictions.
