Blocstop BS load arrester

The BS is an automatic wire rope load arrester that can be activated either manually or mechanically and is limited to material handling only. Its clamping jaws are held open by a lever which is supported on the suspension rope by a roller. If the suspension rope breaks, this support stops and the BS closes.

This reliable device has a Working Load Limit (WLL) of 800kg to 3200kg, making it suitable for a wide range of material handling applications.

If you have any questions about the features and capabilities of the BS model, please don't hesitate to contact us. Our team is here to help you make the best decision for your business.

  • Automatic load-holding safety - Instantly arrests load movement in the event of rope failure or uncontrolled descent, protecting personnel and equipment.
  • Compact, self-contained unit - Integrates easily into new or existing lifting systems without major redesign or complex installation.
  • High-strength, industrial construction - Engineered for demanding environments, delivering long-term reliability and durability.
  • Fail-safe operation - Provides a dependable secondary safety device where controlled load security is critical.
  • Low maintenance design - Minimises servicing requirements, helping reduce operational downtime and lifetime costs.
  • Flexible mounting options - Suitable for a wide range of lifting, handling, and positioning applications.
  • Tested and certified safety performance - Manufactured and validated in line with recognised lifting safety standards for complete peace of mind.
