· Structure and cost: The manual type has a simple structure, light weight, and low cost and maintenance costs; the electric type has more motors and electrical systems, complex structure, and relatively high initial investment and late maintenance costs. · Application scenarios: * The manual type is suitable for light-load and low-frequency applications, such as maintenance workshops, distribution stations, laboratories, etc. Where there is no power supply or only occasional lifting is required.   * The electric type is suitable for frequent and efficient production environments, such as manufacturing workshops, warehouses, assembly lines, etc., which can effectively improve production efficiency.
