Tractel "ETA", "ETC" & "ETM" Pulley Sheave Snatch Blocks for Wire Rope Heavy Duty Off-Shore - Range from 2000kg to 32000kg

The snatch blocks of the ETA/ETC/ETM’s range are mainly used for temporary applications for pulling and lifting, when quick assemblies and/or dismantlings are required. They can be suspended to a fixed or mobile anchorage point with the right strength corresponding to the required load.

Thanks to an easy instalment, a light weight and attached locking parts, these snatch blocks are most often used on vessels and off-shore platforms.

The snatch blocks are available in 3 models with 3 different types of anchorage:

• ETC model with a hook with safety latch for a quick transfer.
• ETM model with a swivel shackle for an optimised and secured anchorage.
• ETA model with an axle suitable for tiny spaces.

• Easy to install.
• Light weight.
• Removable parts secured against loss.

The ETC and ETM models can easily be transformed in an axle model (ETA) by using standard tools. Once the snatch block is not under tension, the opening, operated by turning one bearing flange around the sheave axle, makes the introducing of the wire rope in the groove possible, while the block remains suspended. All the parts stay interdependent during the flange opening and the wire rope introduction.

The locking axle is secured by a safety pin which prevents any unscrewing or uncontrolled movement.
