Caldwell Model 82 Heavy-Duty C-Hook (Coil Lifter / Upender)

The Caldwell Model 82 is a heavy-duty C-hook coil lifter designed for safe, efficient handling of steel coils in demanding industrial environments.

Built for mill duty applications, this lifting hook is engineered to support a wide range of coil sizes and weights while maintaining balance, stability, and durability during overhead crane operations. 

This model is commonly used in steel service centers, coil processing facilities, and manufacturing plants where reliable coil handling is required every day under high loads.

Key Features

• Heavy-duty C-hook design for coil handling
• Capacity range from 5 to 50 tons depending on configuration
• Counterbalanced design hangs level when empty
• High-tensile alloy steel construction reduces weight while maintaining strength
• Curved saddle design supports coil shape and reduces edge damage
• Inside hook radius helps avoid coil edge contact
• Guide handles for safer positioning and operator control
• Optional protective padding available for sensitive coil surfaces
• ASME compliant design for industrial lifting standards

How It Works

The Model 82 uses a classic C-hook geometry, allowing operators to slide the hook into the coil I.D. (inner diameter) and lift from within the coil. The curved saddle supports the coil while keeping it stable and centered during transport.

The counterweighted design ensures the hook remains balanced when not loaded, making crane pickup and positioning more predictable and safer.

Common Applications

The Model 82 is widely used in:

• Steel coil mills
• Metal service centers
• Slitting and processing lines
• Fabrication shops
• Stamping and forming operations
• Warehouse coil storage
• Heavy manufacturing facilities

It is especially effective for high-frequency coil handling where speed and durability matter.

Capacity & Configuration Range

The Model 82 is available in multiple configurations, including:

• 5 ton
• 7.5 ton
• 10 ton
• 15 ton
• 20 ton
• 25 ton
• 30 ton
• 40 ton
• 50 ton

It also supports multiple coil widths (commonly 36" to 84") and varying headroom requirements depending on configuration.

Design Advantages

Heavy-duty mill performance

Built for continuous industrial use in steel production and coil handling environments.

Balanced handling

Counterweight design allows the hook to hang level when empty, improving crane handling efficiency.

Coil protection

Curved saddle and optional padding help reduce damage to coil edges during lifting.

Wide application flexibility

Multiple sizes allow matching the hook to different coil widths, weights, and storage layouts.

Limitations

• Designed specifically for coils only (not general lifting)
• Requires proper crane alignment to center of gravity
• Not ideal for non-coil shaped loads
• Large units require significant headroom at higher capacities
