The basic principle of the twistlock system is the same as that of the ELME hydraulic jacklift, with a "one-of-a-kind" proven design and sound system, thanks to the thousands of ELME hydraulic jacklift spanners supplied to the market.

The spreader is equipped with the same twist-lock assembly as all ELME jack-up spreaders, which not only means a well-known system, but also has advantages in terms of access to spare parts for end users and service providers.
