Steelwrist launches SQ50 quick couplers and tilt-rotators
Steelwrist’s new range of SQ50 quick couplers and tilt-rotators is aimed at 7- to 13-ton excavators. Steelwrist SQ is a high performing fully automatic oil connection technology, used in quick couplers and tilt-rotators on excavators to connect hydraulic work tools, and SQ50 meets the specifications of the Open-S standard for fully automatic quick couplers.
The SQ50 quick couplers and tilt-rotators will debut at the Vei and Anlegg fair in Norway on May 11th to 14th. The SQ50 will be phased in on X12 and X14 tilt-rotators, which means that future S-type quick couplers and tilt-rotators will be upgradeable to SQ-type. S50 and SQ50 quick couplers are steel casted and have the Steelwrist Front Pin Lock safety solution. Front Pin Lock is a mechanical lock of the front shaft which significantly limits the risk of an unintended drop of work tools.
The X12 and X14 tilt-rotators are redesigned with a new top and attachment coupler in order 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. The new generation X12 and X14 tilt-rotators will start shipping out during the third quarter of 2022.
SQ on the top side (upper coupler) of the tilt-rotator for rapid change between tilt-rotator and other work tools, and SQ on the bottom side (attachment coupler) of the tilt-rotator will allow for rapid change between hydraulic work tools. By using SQ, tilt-rotator work tools can be made less expensive as the rotation function is included in the tilt-rotator.
“With the introduction of SQ50 fully automatic quick couplers and tilt-rotators, we will change the game in the growing 10-ton excavator segment with flow capacities of 120 litres per minute with low back pressure. This allows for efficient use of high flow work tools also for mid-size excavators,” explained Stefan Stockhaus, CEO of Steelwrist AB.
With the introduction of SQ50, the Qplus technology has been updated to allow for even higher flows, adding another 20% to flow capacity which allows users to run also the high flow requiring work tools on mid-size excavators. With the introduction of SQ50, Steelwrist will during 2022 also introduce a new Absolute Rotation Sensor in order to give higher accuracy to Machine Control Systems. Together with Steelwrist Autotilt this allows for even higher productivity.
