Electric Lifting Hoist Controller

The Electric Lifting Hoist Controller is a dedicated electrical control device for accurately controlling the operating status of electric lifting hoists. Serving as the "operational core" of the electric lifting hoist, its core function is to receive command signals from operators, and through logical operations and electrical control, drive the hoist's lifting motor and traveling motor (if equipped with a movement function) to perform actions such as lifting, lowering, traversing, starting, and stopping.

Translation of Equipment Status Confirmation Operation Specifications for Electric Lifting Hoist Controller

Before conducting adjustment, maintenance, or repair on the electric lifting hoist controller, it is imperative to strictly implement the equipment status confirmation process, fully identify potential safety hazards, and prevent equipment malfunctions, personal injuries, or property losses caused by misoperation. The following are the detailed operating steps and requirements:

Verification of Personnel Qualifications

Operators must hold relevant qualification certificates for stage machinery operation, be familiar with the structural principles, control logic, and safety operating procedures of the stage electric hoist. Unauthorized operation by unqualified or non-professional personnel is strictly prohibited. Before operation, operators shall wear complete personal protective equipment, including insulating gloves (with a voltage resistance rating of not less than 500V), anti-impact safety shoes, and anti-static work clothes. If high-altitude operations are involved (e.g., the controller is installed in a high-altitude control cabinet), operators must also fasten a double-hook safety belt and confirm that the working platform is stable.

Preparation of Tools and Warning Supplies

Prepare qualified electrical testers in advance (which must be within the validity period, verified as qualified, and whose applicable voltage matches the power supply voltage of the hoist), warning signs with the wording "Under Maintenance, No Switching On" (made of durable plastic or metal, with clear and eye-catching fonts, and a size of not less than 30cm × 20cm), insulating tape, emergency lighting equipment (if the working area has insufficient light), and equipment operation manuals. Only when all tools are in good condition and can be used normally can the operation of the electric lifting hoist controller be carried out.
