The new range of SQ50 quick couplers and tiltrotators is targeted at the 7-13 tonne excavator range. Steelwrist SQ is a high performing fully automatic oil connection technology used in quick couplers and tiltrotators on excavators to connect hydraulic work tools. Outstanding flow characteristics and competitive building height and weight are significant advantages of SQ50. It meets the specifications of the Open-S standard for fully automatic quick couplers.
The SQ50 will be phased in on X12 and X14 tiltrotators which means that future S-type quick couplers and tiltrotators will be upgradeable to SQ-type.
S50 and SQ50 quick couplers are steel casted and have the Steelwrist front pin lock safety solution. The lock is a mechanical lock of the front shaft which significantly limits the risk of an unintended drop of work tools.
Meanwhile, the X12 and X14 tiltrotators have been redesigned. They come with a new top and attachment coupler to make it possible to upgrade from S50 to SQ50 at a later stage, even if the customer did not include SQ in the initial order.
