64 • May 2018 INNOVATIONS EQUIPMENT & TECHNOLOGY Mezzanine structure, lift and access product manufacturer has been awarded U.S. Patent No. 9,834,975 for its "Hazard Alert Device for Ele- vated Barrier," known commercially as the EdgeAlert Open Gate Alarm System. For every elevated plant application where an open gate condition might occur, an early warning device such as EdgeAlert can make the difference in severe worker injury, company officials note. A properly installed EdgeAlert will signal an open gate with a highly visible flashing light and loud alarm. The device can be installed on new or existing swing, slide, tilt or scissor gates. It includes a 120 VAC plug-in power supply, but can also be powered by four long life alkaline "D" cell batteries. A Single-Pole, Single-Throw 30V, 2A, 60W Relay Output is provided for connection to other alarms or safety controls. A dual-channel processor system is self-monitor- ing and will display a "fault" signal if a sensor or wiring problem is detected. For maximum visibility at elevated and ground levels, amber-col- ored LED lights are located on the front and back of the alarm enclosure. When a gate is being used, workers may choose to silence the EdgeAlert alarm for 120 seconds by pressing the "snooze/acknowl- edge" button. However, during such loading or off-loading periods, the highly visible warning light continues to flash. Once an open gate has been closed and secured, users can reset the alarm by pressing the button again, or simply opt for an automatic reset mode. — Wildeck Inc., Waukesha, Wis., 262/549-4000; Mezzanine gate alarm Mini Transmitter is easily customized to meet OEM and system inte- grator requirements for heavy-duty machines and vehicles. With an operating range up to 330 feet, it can accommodate one to six linear levers or up to three joysticks, as well as several pushbuttons and switches. Operator feedback is available via high-performance color or monochrome displays, or LEDs. The unit's ergonomic design sup- ports hours of daily usage without causing operator fatigue. The stop function conforms to performance level "d" as specified in EN ISO 13849-1, a legally binding standard for safety-critical components of control systems. The Mini Transmitter communicates with the corresponding receiver using a Scanreco protocol and a unique identity code, which guarantees that no other transmitter can activate the machine unin- tentionally. In the case of a damaged transmitter, the new unit can be easily connected and paired to the existing receiver. Units are locked like the prior version with no special programming required. — Scanreco, Reston, Va., 855/685-0732; Compact remote control transmitter The latest addition to a broad range of overlay products for high abrasion conditions, Duroxite 300 is presented as a competitive alternative to traditional tungsten carbide alternatives. The overlay material used for Duroxite 300 contains a high volume of an ultra-fine complex borocarbide phase. Grain size is down to 500 nanometers, which makes the borocarbides approximately 200 times finer than traditional chromium carbides. Borocarbides' high wear resistance and increased impact resis- tance allows for a reduced overlay thickness compared to traditional overlays, yielding a ligher product with longer service life. Like com- panion Duroxite products, the 300 plate maintains a consistent wear resistance from the surface down to 75 percent of the overlay. — SSAB Special Steels Americas, Moon Township, Pa., 412/203-1620; www., Borocarbide overlay wear plate
