How to select chain hoist according to actual application

Chain hoist selection must closely reflect the core requirements of the application, taking into account workload intensity, environmental characteristics, and functional requirements. The following analyzes the key selection logic based on typical scenarios.

Manufacturing Workshops: Matching by Work Intensity

Automotive parts assembly lines primarily rely on intermittent lifting, with individual components weighing 1-3 tons and lifting heights of 3-5 meters. An M3-class suspended electric chain hoist is sufficient, paired with a monorail system to meet assembly line shifting requirements. Mold workshops, which require lifting weights of 8-15 tons and precise positioning, must use an M5-class or higher variable-speed model equipped with a grade 80 alloy chain and anti-unhook and overload protection devices to ensure safe heavy-duty operations.

Warehousing and Logistics: Selecting by Frequency and Automation

For general e-commerce warehouses with individual components ≤1 ton and fewer than 20 operations per day, manual chain hoists offer high cost-effectiveness and a lightweight design for easy mobility. Automated high-bay warehouses require 24/7 continuous operation. Choose intelligent electric models that can be linked to a WMS system, support stepless speed regulation and remote control, and feature an IP54 motor rating suitable for dusty environments.

Special Environments: Prioritizing Safety and Adaptability

Chemical workshops require explosion-proof models with Exd IIB T4 or higher, and fully flameproof motors and controllers to eliminate spark risks. Metallurgical workshops, with temperatures exceeding 300°C, choose high-temperature-resistant models with heat-resistant steel chains and forced-air-cooled motors to prevent equipment failure.

Outdoor and Small Applications: Highly Convenient and Durable

Construction sites should choose outdoor models with IP65 rain and dust resistance. The chain should be galvanized for rust resistance, and a slow-down feature should be included for overhead operations. For small applications like auto repair shops, portable manual hoists weighing 15kg or less can be used for 0.5-2 ton operations. For high-frequency operations, use 220V micro-electric models for both convenience and efficiency. The key to model selection is to identify the four elements of "weight - frequency - environment - accuracy" and then match the corresponding configuration to accurately meet the needs.
