Chain blocks, also known as manual chain hoists, are widely used in industries such as construction, manufacturing, and warehousing for lifting heavy loads in confined spaces or where electric hoists cannot be used. The lifting mechanism involves pulling a hand chain, which drives a set of gears to lift or lower the load. Chain blocks are simple to use, portable, and come in various load capacities to suit different lifting needs. These devices comply with safety standards such as ASME B30.21 and SASO 2450 to ensure they operate safely and efficiently. They are ideal for use in both vertical and horizontal lifting operations.
Key Features:
- Manual Operation: Simple, reliable hand-operated mechanism for lifting heavy loads.
- Compact and Portable: Suitable for use in confined spaces or portable applications.
- High Load Capacity: Available in a range of capacities to suit various lifting tasks.
- Durability: Built to withstand heavy use and harsh environments.
Types and Standards:
- Standard Chain Blocks: Basic manual chain hoists for general lifting.
- Heavy-Duty Chain Blocks: Designed for industrial lifting applications.
- **ASME B30.21, SASO 2450: Safety standards ensuring performance and safety.
Brands Available:
Crosby, Kito, Harrington, Peerless, and Lift-All offer high-quality chain blocks for different lifting applications.
General Maintenance:
Regularly inspect the chain, gears, and hooks for signs of wear, corrosion, or damage. Lubricate the chain and gears to ensure smooth operation and prevent rusting. Ensure the hook latch works properly and clean the unit after use. Store in a dry area to prevent corrosion.
