54 • November 2018 INNOVATIONS EQUIPMENT & PRODUCTS The new First Mate davit can lift up to 850 lbs., a 350-lb. boost over the previous model, and can be con- figured with a spur or worm gear hand winch for short, less frequent lifts, or power winch for longer, more frequent lifts. Normally deployed for loads up to 79 feet below floor level, the First Mate can be configured for long lifts of up to 285 feet for use on silos, towers, bridges, mezzanines or roof tops. Pedestal, wall and flush mount bases are easily installed with four anchor bolts. Additional features include quick mount winch bracket with single clevis style pin; bushing along the bottom of the mast, providing smooth and easy 360- degree crane rotation while under load; and, rotational lock plus base extension for an additional 15 inches of height if needed. First Mate has standard red powder coat finish and is available in galvanized or epoxy. — Thern Inc., Winona, Minn., 507/454-2996; Portable 850-lb. crane Company has expanded remote control capabilities for its line of cranes, trolleys and air or monorail hoists. The RC-S, RC-SP and RC-X models have a transmitter and receiver; each can be integrated with existing equipment or combined with a new JDN hoist. The receivers afford rigid and compact design, and can be mounted directly on the hoist or the trolley, or individually at a site. The portable transmitters can run up to 20 hours before recharging. All compo- nents are housed in a space-saving, shock-resistant, glass-reinforced plastic casing featuring dust and water protection. A breathable membrane guides any condensation away from the interior to the exterior. Well suited to long distances between hoist and operator, the JDN RC represents a sensitive alternative to applications with long control hoses. In addition, it can be used in hard-to-reach places and for simulta- neous control of multiple hoists. — JD Neuhaus L.P., Sparks, Md.; 888/638-4287; Hoist, crane radio remote control The RC-S, RC-SP and RC-X radio control remote control transmitters and receiver support safe and convenient hoist and crane control.

With low VOC characteristics, Decra-Seal Natural can be applied by an industrial sprayer, lint-free roller, or lambs wool applicator. Simple clean up entails soap and water.
