Remote control compact loader capability meets end-user demands

The deployment of remote control capabilities in compact equipment continues to expand as contractors and equipment operators seek enhanced operational flexibility and efficiency. While large OEMs have traditionally dominated this technology space, growing end-user demand is now driving innovation across broader categories, including small equipment. This market evolution reflects changing worksite requirements and an increasing emphasis on operator safety and productivity.

My company, Cattron's, recent collaboration with compact equipment manufacturer Baumalight emerged from multiple customer requests for remote operation capabilities in their mini skid-steer equipment. These requests came from diverse sectors, each presenting unique challenges and opportunities that remote control functionality could address.

System integration approach 

Our solution integrates advanced engine management with remote operation capabilities through a two-part system. At its core, Cattron's DynaGen PRO600 controller manages both engine functions and operational parameters, providing precise control of mechanical and electronic engines. This digital control platform enables comprehensive monitoring of machine functions while supporting both mounted and remote operation.

The remote supervision capabilities centre on the CattronControl LRC-S1 radio remote control system, featuring dual multi-axis joysticks that provide up to six distinct motion controls. The unit's hardened construction and IP65-rated enclosure ensure reliable performance in demanding environments, while redundant hardware and software architecture maintains operational integrity. A unique docking system enables operators to transition seamlessly between mounted and remote bellybox operation.

Technical implementation 

Integration of this system into Baumalight's new TRL740 mini compact skid steer required careful attention to both mechanical and control systems. We developed custom wiring harnesses compatible with both Yanmar and Kubota engines, providing Baumalight with flexibility using either of its two standard power plants. The transition from manual to electric-over-hydraulic controls demanded particular attention, resulting in development of adaptive control algorithms that maintain precise operation under varying conditions.

The system continuously monitors critical parameters including hydraulic pressures, fluid temperatures and engine performance metrics. This data enables real-time performance optimization while supporting predictive maintenance capabilities. The control interface provides operators with clear data on operational parameters through a high-visibility display engineered specifically for outdoor environments.

Cattron's approach to integration focuses on maintaining operational flexibility while ensuring reliable performance. The system's modular architecture accommodates various equipment configurations, while standardized implementation protocols simplify adoption by a wide range of other manufacturers. This combination of sophisticated control capabilities with straightforward implementation has proven particularly valuable for manufacturers seeking to add remote control features to their equipment offerings.

Safety in hazardous environments 

A primary candidate for remote operation came from waste management and environmental services, where operators frequently encounter hazardous materials. A large Pennsylvania-based waste management facility recently began using the Baumalight TRL740 remote-controlled skid steer to maintain safe distance during high-risk material handling operations.

Beyond hazardous materials, remote operation proves valuable in a variety of other situations, where operators often work in unstable or unpredictable environments. The ability to maintain distance from potential hazards while maintaining full machine functionality significantly enhances workplace safety.

Increased operational visibility 

Remote operation addresses a common challenge in compact equipment operation — limited visibility in certain applications. When loading materials in confined spaces, near escarpments, or working near structures and other equipment, operators can position themselves from optimal viewing angles, improving both safety and control dexterity.

This superior visibility particularly benefits operations in restricted spaces, such as indoor renovation projects or urban construction sites. Operators can maintain clear sightlines to both the work area and surrounding environment, reducing the risk of collateral damage while improving precision and control.

Applications across equipment categories 

The demand for remote operation extends beyond skid steers to other compact equipment types. Mobile conveyors, for instance, can benefit from remote control during material transfer operations. Operators can position themselves at loading points while maintaining full control over conveyor functions, eliminating the need for multiple personnel or constant mounting and dismounting.

Track-mounted equipment, like mini-vibratory trenchers and self-propelled stump grinders, will gain particular advantages from remote operation. Operators can maintain optimal viewing angles for precise cutting paths while avoiding exposure to dust and larger airborne debris. The technology also enables single-operator efficiency in applications traditionally requiring multiple workers.

Safety considerations 

Safety is engineered into the system through multiple features. The LRC-S1's redundant CANSafe architecture ensures reliable operation, while an optional tilt detection feature can provide additional protection for those operating on uneven terrain. The Baumalight implementation includes emergency stop functionality — a point highlighted by a recent incident where a wheel loader operator experienced a medical emergency and crashed into a building. Such situations demonstrate the value of remote operation capabilities that allow operators to maintain safe distances when handling hazardous materials or working in dangerous environments.The CattronControl LRC-S1 offers multiple redundant safety protocols, including:

• Redundant CANSafe architecture ensuring operational reliability.
• Optional tilt detection capability for operation on uneven terrain.
• Emergency stop functionality accessible from the remote unit.
• Docking system with safety interlocks for transition between mounted and remote operation.
• Environmental protection through IP65-rated housing.

Market response and implementation 

Initial market response has validated the demand for flexible remote operation capabilities on small equipment. In addition to waste management facilities quickly recognizing the technology's value in hazardous material handling, construction contractors have followed, particularly those specializing in confined space operations and environmental remediation.
Recent inquiries to Baumalight have highlighted additional applications, including:

• Demolition operations in unstable structures.
• Underground construction projects.
• Agricultural material handling.
• Industrial cleaning operations.
• Forestry and land clearing.

Future possibilities

Ushered in by the successful collaboration between Cattron and Baumalight, we believe that the table is set for successful integration of remote control capabilities in a broad swath of compact equipment which will continue to evolve, driven by end-user requirements and technological advances. Cattron's development will focus on expanding application-specific features while maintaining system reliability and ease of implementation.

Emerging opportunities may include integration with semi-autonomous operations, where remote control serves as a backup for automated systems. This capability could prove particularly valuable in repetitive operations where full automation may not be practical or desirable.

More control

The implementation of remote control capabilities in compact equipment for small manufacturers represents a sea change that should level the playing field, while increasing industry competition. By enabling more operators to choose between mounted and remote operation based on specific task requirements, we hope to see the adoption of this technology enhance both efficiency and safety across diverse applications.

As market demand continues to grow, we expect further expansion of remote control integration across various equipment categories. This evolution, driven by practical end-user requirements rather than technology for technology's sake, demonstrates the industry's interest in responding effectively to expanding opportunities and operational needs.
