In a time when automation and operator safety are becoming increasingly critical, manufacturers of compact construction equipment are facing growing pressure to offer remote control capabilities. However, the cost and complexity of developing proprietary, technically demanding systems have typically limited these features to large OEMs. A recent collaboration between control systems specialist Cattron and compact equipment manufacturer Baumalight demonstrates how this barrier can be overcome, bringing a new level of competitiveness to every corner of the yellow iron market—and beyond.
RAPID DEPLOYMENT
The project began when Baumalight, a Canada-based manufacturer of mini skid-steer equipment and related specialty attachments, received customer requests for wireless remote-control capabilities. Rather than attempting to develop an in-house solution, they approached Cattron, with whom they already had a relationship through the use of Cattron’s engine control panels.
The collaboration expanded into a comprehensive control system integration project that would ultimately transform their mini skid-steer equipment. The TRL740 series skid steer is a new offering that came as a result of upgrading the company’s TRL620 to include a larger engine, bigger, higher-flow electronic pumps, wider tracks, and a beefier frame. Baumalight felt it was the perfect time to incorporate Cattron’s radio remote control and engine control capabilities.
The integration process occurred in two main phases. The first phase, lasting six to eight months, focused on implementing advanced engine and machine control using the Cattron DynaGen PRO600 controller. The DynaGen PRO600 provides engine and generator control for autostart or manual operations on mechanically or electronically governed engines. The TE600 and TG600 engine and generator controllers offer CANbus and Modbus communication, 22 inputs and 10 outputs, ruggedized for use in extremely harsh environments.
Cattron’s digital control system replaced Baumalight’s basic manual controls and provided enhanced monitoring capabilities, including hydraulic system parameters and maintenance indicators.
The second phase, requiring an additional six to eight months, integrated the CattronControl LRC-S1 radio remote control system.
SEAMLESS INTEGRATION
The solution combines several key technologies. At its core is the PRO600 engine controller, which provides complete control and protection of the vehicle’s engine. The system features a sunlight-readable color display and offers extensive configuration options for startup speeds, diagnostic readouts, and sensor feedback.
For wireless remote operation, the LRC-S1 bellybox and new CBMCU receiver enables control of up to six motions through two multi-axis joystick controllers and an axis switch. The system includes redundant hardware and software architecture for safety, along with the IP65-rated bellybox for durability in demanding environments.
A unique aspect of the implementation is the docking system, allowing operators to use the same control unit whether operating the machine from the ride-on platform or remotely once they dismount. Cattron also offered Baumalight its private labeling capabilities, creating a product package that matched Baumalight’s brand.
The integration required significant mechanical and electrical modifications. Baumalight upgraded from manual hydraulic controls on its TRL740Y to electric-over-hydraulic systems, working with local hydraulic integration partners to implement proportional control valves and pumps. Cattron developed custom wiring harnesses compatible with both Yanmar and Kubota engines, providing Baumalight with tailored solutions for their two power plant options.
PERFORMANCE IMPROVEMENTS
The transition to electronic control yielded benefits beyond remote operation. Operators reported enhanced responsiveness and precise control compared to the previous manual hydraulic system. The digital interface provides real-time monitoring of critical systems, including fluid temperatures that were previously invisible to the equipment’s users. The system’s event log capability also allows monitoring of the engine operation and maintenance needs.
SAFETY AND EFFICIENCY
Safety was a primary consideration in the system’s design. The LRC-S1’s redundant CANSafe architecture ensures reliable operation, and while the system’s optional tilt detection feature was not part of the initial skid-steer upgrade, the option can add an extra layer of protection for those operating on uneven terrain. The remote-control capability allows users to maintain a safe distance when working in dangerous environments.
The system also improves worker efficiency and performance. Operators can position themselves for optimal visibility when loading or maneuvering in confined spaces. The ability to control the machine from an off-vehicle vantage point reduces the physical strain of repeatedly mounting and dismounting the equipment.
MARKET ENTHUSIASM
The first prototype, initially intended for Baumalight’s rental fleet, quickly attracted customer interest. A large Pennsylvania-based waste management facility ordered the machine immediately after viewing demonstration videos, particularly valuing the remote-control capability for handling hazardous materials. This rapid market validation has led Baumalight to standardize the PRO600 control system across their production line, with remote control available as an option.
EXPANDING APPLICATIONS
Beyond skid steers, remote-control technology offers compelling benefits across a wide range of construction equipment from stump grinders, buckets, and winches to compact concrete pumps and cranes.
Safety applications extend well beyond basic remote operation. For heavy equipment like dozers and wheel loaders, remote emergency-stop capability provides an additional layer of protection. In one recent incident, an operator experienced a medical emergency while operating a wheel loader, resulting in the machine crashing into a building. A remote E-stop system, like that on the LRC-S1, would have allowed supervisory personnel to immediately shut down the machine.
The technology’s versatility stems from Cattron’s integrated approach to equipment control. Rather than treating remote operation as a standalone feature, the system combines radio remote control, engine management, and telemetry capabilities. This enables contractors to not only control their equipment remotely but also monitor performance parameters and maintain operational efficiency.
INDUSTRY IMPLICATIONS
This collaboration demonstrates how smaller equipment manufacturers can access advanced control technology without extensive in-house development. The modular approach, combining engine control, hydraulic system management, and remote operation, provides a pathway for manufacturers to enhance their equipment’s capabilities while maintaining competitive pricing.
A WIN, WIN, WIN
The Cattron-Baumalight collaboration illustrates how partnerships between control system specialists and equipment manufacturers can bring advanced capabilities to market segments previously underserved by automation technology.
For contractors and construction firms looking to enhance both safety and productivity, these capabilities will help transform traditional equipment into more versatile, efficient tools that can be adapted to a broader range of applications and working environments.
