Blocstop® BSO
The Blocstop® BSO is an automatic, fall-arrest secondary safety device which is fitted to the wire rope of a Tirfor®/Griphoist® or Tirak® hoist.
The Blocstop® BSO protects against hoist failure and, if mounted on a separate safety wire rope, against suspension wire rope failure.
The Blocstop® BSO is suitable to hold or restrain any loads during lifting and pulling applications.
When in overspeed, the Blocstop® BSO automatically engages and locks on wire rope. The BS/BSO for double rope suspension provides a locking device for the primary and secondary wire ropes.
