Quick couplers with or without integrated oil couplings

Steelwrist symmetrical couplers are cast in steel. Large pin contact surfaces, optimized use of materials and no weak weld seams make our coupler extremely compact and robust. We offer three types of coupers; automatic, hydraulic and mechanical. The coupler type defines if the coupler is automatic, hydraulic or mechanical. Automatic couplers are the type of couplers that use a quick coupler line for the locking function, but at the same time connect the hydraulics to any powered work tool automatically. Hydraulic couplers use a quick coupler hydraulic circuit, so you can change between work tools from the cab. However, to change to an hydraulically powered work tool, like for example a grapple, you still need to go out of the cab and connect the hydraulic hoses.

Finally, we have the more basic mechanical coupler, where you must get out of the cab and unlock it manually when you want to change work tool. The coupler standard defines the interface between the coupler and the work tool. All our couplers follow the Open-S (OS®) symmetrical standard, for the mechanical, hydraulic as well as the electrical interface.

Safety in focus

Jobsite safety is paramount. Steelwrist has developed systems for enhanced safety on quick couplers for excavators that minimize the risk of a dropped bucket or work tool.

Steelwrist machine couplers and tiltrotator couplers come either with LockSense, Front Pin Lock or Front Pin Hook, machine independent safety solutions that work on all types of excavators, regardless if they are small, large, new or used. All solutions comply with international safety regulations such as EN474 and ISO13031.

Compact and steel cast

Steel casting is a cornerstone in our design philosophy. Steelwrist is the only manufacturer on the market that have a symmetrical coupler completely cast in steel.

Free from welding, large pin contact surfaces and optimized use of materials, makes it an extremely compact and robust coupler. High tensile steel casted products have an unbeatable relationship between strength and weight.

Changing powered work tools in seconds

With an automatic coupler solution the hydraulic connection is integrated in the quick coupler and makes it possible to change hydraulic powered work tools, as well as mechanical work tools, in only seconds – all without leaving the cab. We call this the Steelwrist SQ auto connection system.

Steelwrist offers a complete range of automatic SQ couplers, available for excavators from 2-70 tonnes.

Compliant with open industry standards

We believe in open standards. All Steelwrist couplers follow the independent and established Symmetrical standard (S-standard), which is the internationally fastest growing type of quick coupler for excavators.

Steelwrist automatic couplers are in compliance with Open-S (OS®) – the open industry standard for automatic quick couplers for excavators. With an open standard, machine operators and contractors can more easily choose quick couplers, tiltrotators and work tools from different manufacturers that are in compliance with the standard, and be confident that they will work together.

SQ Full Automatic Quick Coupler Systems

Changing powered work tools in seconds

Steelwrist SQ is a high performing full automatic oil connection technology used in quick couplers and tiltrotators on excavators to connect hydraulic work tools. Fully automatic quick couplers are becoming increasingly popular in the demolition and construction industry thanks to the greatly enhanced productivity, safety, and comfort benefits.

With Steelwrist SQ technology you can change between hydraulic powered work tools such as breaker, crusher, shear, grapple as well as mechanical work tools in only seconds – all without leaving the cab!

Hydraulic couplings with Qplus™ technology

In 2017 we introduced our patented Qplus™ technology which radically changes the “inside” of the hydraulic couplings and makes us unique in the market.

Higher flow, more uptime and improved serviceability are the main benefits for the operator.

Front Pin Lock safety solution

With Steelwrist entrance into the demolition segment the Front Pin Lock was upgraded to a second generation in order to support the heavy demolition work tools.

Quick Coupler Controller

If your excavator is not prepared for a quick coupler system Steelwrist offer a Quick Coupler Controller for controlling and monitoring the quick coupler functions such as locking, unlocking, and optional pressure relief for SQ couplers.

The control system module is installed in the cabin and the indicator panel provides clear and easy indications of the various functions and peace of mind for the operator.
