Laird Technologies - Underground Communication and Radio Remote Control Systems for Mining Applications

Laird Technologies designs, manufactures and installs technologically advanced underground communication systems and portable radio remote control systems for mining applications; providing safer operation, increased production, reduced downtime and lower operating costs for our customers.

Our remote control systems are engineered for mining machinery including voice and data systems for underground communications, load-haul-dump vehicles, CAN remote control systems, and portable video systems that work with our remote controls, providing the operator with visual contact at a greater distance.

We constantly strive to engineer superior products with outstanding performance ensuring that we always provide the level of quality the global marketplace demands.

Underground communication systems

The SIAMnet underground communication system combines the speed of fiber optic system data communication with leaky feeder voice communication at a fraction of the cost of installing the two systems individually.

Voice communications are supported by 800MHz, analog two-way radios with up to 32 simultaneous conversations, allowing better and farther propagation into underground mines. Telephone interconnect permits receiving or making external calls; mobile communication is enhanced by 800MHz high-speed data communication between the vehicles and the central computer, and WIFI access points enable mobile computing.

Diagnostic LEDs simplify troubleshooting and indicate system status. IP cameras provide real-time images to every network user and, in the event of an emergency; a tagging system provides the last employee location. This modular and scalable system supports current data communication needs as well as the expanding data communication needs of the future.

Remote controls for CAN-based mining vehicles

Part of the Laird Technologies product family, the CANopen remote control is engineered with safety and productivity in mind. The system greatly simplifies the installation of a remote control on any CAN-based vehicle. 

When connected to a CAN network of the vehicle's main computer or PLC, the machine control unit (MCU) acts as a wireless gateway between the vehicle and the operator control unit (OCU), allowing the operator to remotely control a CANopen vehicle through an RF link.

All functions executed on the OCU are transferred on the CAN network and vehicle vital signs are transmitted back to the OCU.

Wireless remote control system

Laird Technologies' LRC-M1, with a lightweight, impact resistant housing, allows the operator to control up to four motions with two multi-axis joystick controllers.

As part of Laird Technologies' new product series, the LRC-M1 wireless system uses an external TransKey™ RFID configuration for efficient operations, minimizing spares and transfer keys to other controllers, increasing safety, reliability, flexibility and workflow.

Portable remote control systems for LHD vehicles

The Laird Technologies AT16LHD and AT32LHD portable remote control systems provide reliable, efficient and convenient control of LHD equipment. This control system duplicates the manual controls in the cab of the load-haul-dump, allowing the operator to direct the equipment from a safer location.

Portable video remote control systems for mining

Laird Technologies' PVS800 portable video remote control system gives the operator clear visual contact at a greater distance.

The system is composed of two machine-mounted video cameras, housing and bracket for an optional third camera, machine-mounted video transmitter, and a video receiver/monitor mounted on the operator's portable controller.

The PVS can be used with Laird Technologies' AT16LHD and AT32LHD systems as well as with other manufacturer's equipment.
