New Product Spotlight: Hoists
HOIST DRIVE FOR DC SYSTEMS
Crane & Hoist Drive is a suitable replacement for electromechanical controls, and can be powered by existing 250 or 500 V DC rails. Its solid-state design eliminates commutator faults caused by brownouts and provides load-independent hoist and lower speeds for positioning accuracy. Unico Inc.
RESTYLED WINCH HOIST
Winch-hoist design includes a revised spur gear housing and cover for easy maintenance. Oil capacity is larger for better cooling and longer life. Lifting capacities range from 1,000 to 6,000 pounds. My-te Products Inc.
ICON-BASED DRIVE INTERFACE
The SP600 offers an intuitive operator interface for its AC drives, with large graphical LCD display and icons depicting functional groups for selection. These icons provide a simple method of locating and accessing drive variables. Rockwell Automation
REDUCE DOOR DOWNTIME COSTS
The Welterweight knockout-style dock door handles the day-to-day knocks from vehicle impact. It rides on spring-loaded plungers rather than bendable rollers. Upon vehicle impact, the plungers release the panel from its guides. The driver snaps the pins back into place and the door is ready to operate. The track design, using Impact-A-Track, means the door can be knocked outward, but not pushed inward, which helps security. To handle lift truck mast problems, the door offers an optional double knockout header. TKO Doors
