Safety Lock/Latch: Load Capacity Up to 5000 kg

Component Specifications

Definition

A precision-engineered safety component designed for quick-attach systems in industrial machinery, featuring a positive locking mechanism that engages automatically when attachments are connected and requires manual release to prevent unintended disconnection during operation. It incorporates visual and tactile indicators to confirm secure engagement.

Working Principle

Operates on a spring-loaded cam or pawl mechanism that engages with a mating slot or groove on the attachment interface. When the attachment is properly positioned, the lock automatically snaps into place under spring tension. A secondary manual release lever or button must be activated to disengage the lock, ensuring intentional detachment only.

Materials

High-strength alloy steel (e.g., AISI 4140) for load-bearing parts, zinc-plated or powder-coated for corrosion resistance; stainless steel (e.g., 304 or 316) for components in corrosive environments; engineered polymers (e.g., POM or PA6) for non-critical parts to reduce weight.
