On-site operation for power transmission lines often requires hoisting tools and testing equipment.Traditional methods predominantly rely on manual or winch-based hoisting

which results in high labor intensity and low efficiency due to environmental and operational requirements.This paper develops a portable intelligent hoisting device that a single person can carry by analyzing the hoisting mechanisms used in the on-site operations of transmission lines.The device integrates the frame

transmission mechanism

motor

battery

and control module in a compact package.Weighing only 10 kg

the device can be easily transported by a single person and has a hoisting capacity of up to 200 kg.It displays the remaining battery life

adjustable hoisting speeds

and power failure protection.This portable lifting device is adaptable for different on-site operation environments

effectively addressing the challenges associated with hoisting tasks in transmission line maintenance.It significantly reduces labor intensity while enhancing the quality and efficiency of hoisting operations.
