Intelligent Driver Access Control and Fleet Management Systems- TruckLOG

TruckLOG - Battery Management System

TruckLOG TK5 is one of the most advanced driver access control and fleet management systems available and gives a new perspective on battery monitoring. Misuse of batteries in forklift trucks is a very common occurrence within both small and large operating areas and can cost thousands in replacement batteries. Batteries are consumable items, and often costs are hidden, but they are also one of the most crucial components of a forklift truck. Ensuring batteries are used correctly – such as charging at the right time and not running them too low – can instantly increase the lifespan of batteries and ultimately saving costs.

MineWATCH - Power Supplies & Relays

MineWATCH - Uninterruptible Power Supply for Hazardous Environments

The MineWATCH PS21-B from Davis Derby Ltd is an advanced uninterruptible power supply unit designed to provide reliable power continuity in demanding environments. This unit builds upon the MineWATCH PS21, featuring an 8Ah battery pack to ensure uninterrupted power delivery. Its robust construction includes a cast steel flameproof enclosure, housing the main transformer and Minewatch PC21-R relays, with six FLP entries for supply and control cables, enhancing safety in hazardous conditions. The PS21-B offers a regulated 12V dc output, maintaining a minimum of 11.5V under full load conditions, up to 700mA, for 8 hours. It includes an intrinsically safe battery enclosure made of sheet steel, as well as an intrinsically safe terminal chamber for connecting to controllers or sensors. This power supply unit can be directly connected to the Minewatch PC21 controller, forming a composite unit, and features an opto output for safe transition indication between mains and battery power in intrinsically safe setups.

MineWATCH - Speech Communications

MineWATCH - Intrinsically Safe Communication System for Mining

The DIS 5 system is an ATEX M1 certified communication solution designed for mining environments, leveraging a four-core cable to facilitate communication and pre-start warnings across long distances. Powered by a 12-volt intrinsically safe supply, it accommodates multiple amplifiers. Each amplifier features a trickle-charged NiMH battery for standby power during mains outages. Components include a console amplifier, remote amplifiers, a pre-start warning generator, safety couplers, and a power supply. The console amplifier, in a robust metal case, supports local and surface communication and call tones. Remote amplifiers direct audio along mining paths with dual speakers. The system integrates into control frameworks, with options for combined units for coal face operations.
