An Array of Innovations
Products that connect, illuminate, measure and transport are introduced.
Wireless Coverage Solution for Elevators
Zinwave, a division of McWane, Inc. of Birmingham, Alabama, has introduced a wireless coverage solution for elevators based on its UNItivity platform, a wideband architecture that supports frequencies from 250-2,700 MHz. The solution utilizes small, fiber-fed remote amplifier units in each cab that Zinwave states can eliminate the challenges of maintaining consistent cellular and public-safety wireless signals. To achieve wireless coverage in the past, building owners deployed distributed antenna systems (DASes) in elevator lobbies or at one end of the elevator shaft. With DASes, elevator cars’ mobility made it difficult to maintain a consistent signal. Zinwave states its on-car remote amplifiers, which are thin, light and fiber fed, ensure strong and consistent wireless service.
Portable Explosion-Proof LED Work Light
Larson Electronics has released a new pedestal-mount LED work light that can illuminate up to 9,000 sq. ft. in a flood pattern. The EPL-PM-150LED-WG-100 is rated Division 1 and 2 for both Class 1 and 2. It is mounted within an A-frame portable stand constructed from non-sparking aluminum and powder coated. It is intended as the LED alternative to a 400-W metal-halide lamp, using less energy and producing less heat.
Featuring an aluminum wire guard for added protection and multiple LED drivers to help increase its lifespan, the light is comprised of a 16-in.-wide by 14-in.-tall rectangular light head mounted within a pedestal base stand with a carrying handle. It produces 12,000 lm of light and can be adjusted up or down 90° and locked into position by manipulating two hand screws. Its power cord is 100 ft. long and is 16/3 chemical and abrasion resistant. An explosion-proof cord cap enables easy connection to explosion-proof outlets.
Digital Measurement for Gears
Siemens unveiled its digital measurement technology for gears, Flender Gearlog, at Hannover Messe 2016 in April. The technology entails the capture of values relating to rotational speed; torque; temperature; and, in the future, vibration by special sensors. The system sums these readings in parallel with machine-capacity utilization. The measurement results are logged, saved and digitally depicted in compressed form. Operators are able to visualize the results at any time or read them in the form of a dataset. The measurements enable conclusions to be drawn about the applied load and loading capacity of gears when used in specific applications. The full transparency of operating data means it can be used to identify possible sources of damage, capacity reserves and overloading in the measured gear.
The product comprises a software solution linked to a hardware component and sensor equipment coordinated in line with the gear. It allows application-specific load collectives, which often vary for operational reasons, to be matched against the operational stability of individual gear components and other elements of the drive train. Siemens states that the technology can be used in the elevator and escalator industry if its gears are used in combination with a shaft with a 40-mm diameter. A pilot phase for the product of around one year has begun.
The SkyBuildTM self-climbing construction elevator is now a standard option in Otis’ SkyRise® line. Otis describes SkyBuild as a time- and money-saving option. Installed at the start of construction, it allows movement of tools and crews quickly and safely — without an external lift or exposure to the elements. Its hydraulic piston system enables the elevator to quickly climb one floor at a time as a building rises. Once construction is complete, the SkyBuild elevator transitions for immediate service as a SkyRise elevator. According to Otis:
“Each SkyRise installation integrates advanced technologies to promote the seamless, safe operation of the entire system. The sustainable design reduces space requirements and energy use compared to conventional systems.”
