Product Description
CM 640 Puller Lever Chain Hoist – Proudly Made in the USA
The CM 640 Puller Lever Chain Hoist is a true American classic—one of the only lever hoists still made in the USA. Trusted by professionals for generations, it delivers rugged strength, smooth operation, and proven reliability for pulling, lifting, dragging, and tensioning applications in demanding environments.
Built for Strength and Longevity
Constructed from a tough aluminum alloy housing with a durable powder coat finish, the CM 640 is built to perform in harsh outdoor or industrial conditions. Its long-handle design provides more leverage with less effort, while the Hoistaloy hardened steel load chain ensures exceptional wear life and flexibility. Every hoist is engineered for consistent, safe performance—job after job.
Safe, Dependable, and Proven
The Weston-type automatic braking system offers positive load control in all lifting positions, and forged hooks with safety latches come standard. Simple internal construction makes maintenance easy and keeps downtime low. Each unit is metric-rated and backed by a lifetime warranty—a mark of genuine American craftsmanship.
