Structural components:
1) Dump line Dump line is tied to the exhaust valve of the parachute lift bag and can be operated by the diver to open or close the exhaust valve to control the underwater air lift bag
2) Web sling A set of slings connected to the bottom of the lift bag and intersecting with the lifting ring
3) Restraining or hold-back line A rope used to prevent the lifted weight from rising uncontrollably with the underwater air lift bag
4) Dead man anchor A fixed structure or independent anchor point used to restrain the load
PLB is extremely versatile, with a single point fixing that is ideal for structures such as submerged static pipes and formwork, allowing for safe support and lifting of heavy objects from any depth.
Highly wear resistant, it resists damage even in the harshest conditions.
Can be towed on the surface at speeds up to 2.5 knots with a suspended load in slightly stable water conditions.
High safety factor
• Meets IMCA D-016 and ABS PDA
• Overall WLL is 5:1, sling WLL is 7:1
• Full implementation and testing of safety flip line requirements
• Specially designed sling marking and inspection scheme to ensure connection errors are avoided
