Safety handrails are now a standard feature on all Liebherr crawler cranes, and a retrofit handrail package is available for existing cranes. The handrails are intended to protect against falls where it can be difficult for operators and maintenance technicians to tie off a safety harness and are compliant with OSHA fall height regulations. They are made of hot-dipped galvanized steel and do not require any maintenance. On Liebherr HS series crawler cranes like the one seen at right, the handrails can be pulled out and removed for transport, while on LR series cranes they can be folded down by releasing a few pins.

LOEA Radio Transmitters use millimeter-wave technology in the 70-86 GHz range to transmit up to 1.5 Gb per second of data. One pair of transmitters is able to cover a 2-mile distance with line of sight, and multiple units can be configured back-to-back to greatly extend the transmission distance without loss of signal. They can be quickly set up and relocated compared to laying fiber-optic lines, and are fully FCC licensed and certified. Loea Corporation; 808-521-4908; www.loeacom.com
