This unit can store up to 4,400 feet of ½" diameter fiber optic cable and control the ascent and descent of the aerostat balloon at speeds up to 115 feet per minute while providing up to 5,500 lbs. of single line pull capacity.

This self-contained hoisting system features one of APPI's proprietary AutoAdvance Line Spoolers with a bull's-eye fairlead to allow launch and recovery of the aerostat in any direction while maintaining proper spooling of the cable. As the aerostat supports a communication platform, the system's ability to support precision launching and recovery is a key feature.

The EHS-5-43D hoist system is powered by a 40 HP diesel generator with sound attenuating enclosure. Features of the system include variable speed payout and recovery via proportional joystick controls. A digital measurement package with line speed, distance and line tension readouts, along with programmable alarms, allow for ease of use and additional operator safety.

APPI has been providing winches, hoists, and positioning systems to industrial, commercial, and military customers for more than 25 years.
