Steelwrist expands its range of quick couplers and tiltrotators with SQ50, a fully automatic high-flow and Open-S compatible solution for medium excavators.

The new range of SQ50 quick couplers and tiltrotators is designed for excavators from 7-13 tons. Steelwrist SQ is a high-quality fully automatic oil connection used in quick couplers and tiltrotators on excavators to connect hydraulic attachments. Excellent flow characteristics and competitive build height and weight are key advantages of SQ50. SQ50 meets the specifications of the Open-S standard for fully automatic quick couplers.

The SQ50 quick couplers and tiltrotators will be shown for the first time at the Vei and Anlegg fair in Norway from May 11-14, 2022, and unfortunately not at the TKD in Almere, as it was cancelled.

The SQ50 will be phased in on X12 and X14 tiltrotators, meaning future S-type quick couplers and tiltrotators can be upgraded to SQ-type.

S50 and SQ50 quick couplers are cast steel and feature the secure Steelwrist Front Pin Lock double locking feature. Front Pin Lock is a mechanical locking of the front axle that significantly reduces the risk of unintentional dropping of attachments.

The X12 and X14 tiltrotators have been redesigned with a new suspension and quick 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 original order. The first new generation X12 and X14 tiltrotators will start leaving the factory in the third quarter of 2022.

SQ at the top (suspension) of the tiltrotator for quick changeover between tiltrotator and other attachments, and SQ at the bottom (quick changer) of the tiltrotator provide quick changeover between hydraulic attachments.
By using SQ, attachments for tiltrotators can be made cheaper, since the rotation function is included in the tiltrotator.

"With the introduction of SQ50 fully automatic quick couplers and tiltrotators, we become a game-changer in the growing 10-ton excavator segment with flow capacities of 120 liters per minute with low back pressure. This enables efficient use of high-flow attachments, even for medium-sized excavators," says Stefan Stockhaus, CEO of Steelwrist AB.

High flow hydraulics and absolute rotation sensor
With the introduction of the SQ50, the Qplus technology has been updated to enable even higher flow rates, adding another 20% to the flow capacity, allowing users to also use the high flow rate that attachments require on medium excavators.

With the introduction of SQ50, Steelwrist will also introduce a new Absolute Rotation Sensor in 2022 to give higher accuracy to Machine Control Systems. Together with Steelwrist Autotilt, this will provide even higher productivity.

Open-S compatible solution
All Steelwrist SQ products follow the worldwide Open-S industry standard for fully automatic quick couplers for excavators. This means that the SQ system is designed to connect to other brands according to the Open-S standard.
