Steelwrist’s New QuantumConnect Brings Modular, Connected Control to Tiltrotators

Next-Gen Control Platform with New Joysticks, Modular I/O and Built-In Connectivity

Tiltrotators keep gaining ground in North America. Smarter controls make them easier to install, run and support. Steelwrist’s new QuantumConnect platform targets those pain points with modular hardware, app-based setup and over-the-air updates. QuantumConnect is Steelwrist’s new control system platform for its tiltrotators. It replaces prior control electronics with a modular, CAN-based architecture. It adds new A9 joysticks, haptic feedback and an integrated connectivity gateway for cloud backup, diagnostics and updates. Rollout begins in 2025 on selected models. Steelwrist plans a phased launch through its dealer network. From the press release:

“With the QuantumConnect control system platform we take a leap forward in making tiltrotator installations easier than ever before, which has been a top priority for us. Our engineers have put a lot of effort into making sure the control system can easily be adopted to different excavators and be updated over time and I am very proud of what we have achieved. Now I look forward to seeing installations starting to happen across the world”, says Markus Nilsson, Steelwrist CTO.

We can’t exactly tell from the info provided, but the company is probably starting the QuantumConnect platform on larger models. Usually mini excavators are the last to get the coolest, new tech.

Hardware Highlights

• A9 joysticks: Two or three rollers per stick, a 5-way mini-stick switch, optional heated handles
• Haptic feedback: Tactile prompts from the system guide the operator without cluttering the display
• Tiltrotator control module: Mounted on the tiltrotator for precise valve and sensor control
• QIO modules: Convert CAN data to analog and digital signals for machine functions and external systems
• AUX module: Manages extra hydraulics like blades, outriggers or offset booms
• Optional in-cab display: Compact touch display if the excavator HMI is not integrated

The design aims to fit any major excavator brand with machine-specific harnesses and fewer custom parts.

Connectivity Built In

A new Connectivity Gateway handles:

• Wireless links to sensors and components
• 4G for cloud backups, remote diagnostics and software updates
• Data paths for future MiC 4.0 standards and machine control integrations

This enables remote support without laptop cables or special adapters. Fleets can standardize settings and push updates across machines.

InstallMate Speeds Setup

QuantumConnect pairs with InstallMate, a mobile app that guides techs step by step. The app uses model-specific templates, stores configurations in the cloud and supports cloning machine profiles. Install guides update continuously from field feedback. The goal is faster installs, predictable outcomes and simpler support.

Operator Features

• Proportional control on all tiltrotator functions
• Auto-calibration of hydraulic valves to smooth movements and boost efficiency
• User profiles tied to operator preferences and specific tools
• ToolRec to detect the connected attachment and auto-load settings
• LockSense integrated work tool locking confirmation on both machine and tiltrotator couplers
• Optional track and wheel steering from the joysticks to reduce hand movement
• QuantumConnect mobile app (iOS and Android) for settings, backups and wireless service access
• OptiLube integration for automated lubrication status and cartridge alerts

Together these features aim to cut downtime, shorten learning curves and reduce setup guesswork.

Machine Control Readiness

QuantumConnect is designed to work with leading machine control suppliers. The platform’s CAN and I/O modules, plus MiC 4.0 preparation, set the stage for tighter grade control integration over time.

Availability

Steelwrist will roll out QuantumConnect globally during 2025. Availability depends on model and region. The platform ships with both the QuantumConnect app and the InstallMate app for iOS and Android. It carries RED and FCC compliance and is built for future standards.

Tiltrotators: Quick Refresher on Benefits

If you are new to tiltrotators, here’s a short list of advantages:

• Less repositioning: Rotate 360 degrees and tilt up to ~45 degrees for faster cycle times
• Cleaner finish work: Grade, backfill and shape without moving the machine as much
• Fewer machines on site: One excavator can handle forks, grapples or brooms with fast swaps
• Lower wear: Less tracking means less undercarriage wear and ground damage
• Safety and efficiency: Stay in the cab for many tool changes with the right coupler setup
• Less fuel: Less repositioning and less rework means less fuel used.

These gains show up fastest on utility, landscaping and site finishing work where precision matters.

What Caught Our Eye at bauma 2025

Steelwrist has a cool focuse on mini excavators at the 2025 bauma show in Germany. The SQ40 automatic coupler pushed its high-flow, fully automatic interface down below 7 metric tons. Steelwrist demonstrated rapid, in-cab tool changes and cleaner hose routing on two minis. The smaller SQ hardware helps bring big-machine coupler speed to compact carriers. That mini focus aligns with where North American growth continues. Contractors want faster attachment workflows on 2- to 7-ton machines without leaving the cab.

Bottom line

QuantumConnect targets three big hurdles: installation complexity, operator setup and support. Modular hardware shortens installs. App-based profiles standardize fleets. Built-in connectivity unlocks remote updates and service. It won’t hit most minis on day one, but Steelwrist’s mini-focused coupler work suggests the platform will move downrange. For contractors investing in tiltrotators, simpler installs and connected support can pay off as much as the hardware.
