Our friends and colleagues have developed a great system that can replace heavy and awkward pulleys. With a 7P Recovery Ring system (consisting of a lightweight ring and soft shackle), you can be rid of a heavy and difficult to stow pulley system.
There are two versions of the Recovery Ring – a smaller “Red” system designed for motorcycles, ATVs and UTVs and a larger “Blue” system for use by standard sized 4x4 vehicles.
Designed to be lightweight and simple to deploy, you’ll wonder how you ever got along without one!
What is a Recovery Ring?
The Recovery Ring is a simple device to provide mechanical advantage in off-road rigging and recovery situations. Combined with a soft shackle this system can be used to replace a conventional pulley block.
How does it work?
The Recovery Ring can be used wherever you’d need a pulley – for changing direction of a winch line, mechanical advantage or to slow down winching operations. Multiple Recovery Rings can be combined for additional mechanical advantage. The Recovery Ring acts as a single sheave that is attached to a recovery point by the soft shackle and a winch line runs through the groove around the circumference of the ring.
What benefits does it have over a conventional pulley?
It’s smaller and lighter. It’s also quite simple – it has no moving parts. It doesn’t get blocked up with mud.
Can I use steel wire rope on a Recovery Ring?
No. The aluminum alloy will be damaged by steel wire rope. They are designed to be used only with synthetic winch lines.
What is it made from?
All the Recovery Rings are made from 7075 aluminum alloy, with a T6 temper. It has high strength and low weight and 7075-T6 is commonly used in aerospace applications. The soft shackle is made from quality Dyneema fibres (a Ultra-High Molecular Weight Polyethylene), made into 12/13mm (3/8”) rope by Sampson Rope (USA), Atlantic Braids (Canada) or Marlow Rope (UK, USA).
Does it get hot?
No. While there is obviously some friction which generates heat, the recovery process is generally pretty slow and does not approach the melting point of Dyneema fibres, which is around 150C / 300F.
What are the Recovery Rings rated to?
The Red Recovery Ring (for motorcycles, ATVs and UTVs) has a Minimum Breaking Strength (MBS) of 50kN (11240lbs). The Blue Recovery Ring (standard 4x4’s) has an MBS of 180kN (40465lbs). Remember that the Recovery Rings are a part of a system, and need to be paired with the correctly rated soft shackle.
