Maintains Positive Tension

Maintains positive manual tension on the cable as it extends and applies a heavy load over the length as it retracts while maintaining a clean and tight cable storage on the rescue hoist drum.

Hydrostatic Hydraulic Drive

The hydrostatic hydraulic drive consists of a 24-volt drive motor coupled to a hydraulic pump. The system uses Mil-H-5606 hydraulic fluid or other fluids such as Mil-H-83282 or general purpose AW hydraulic fluid specified by the customer.

Batteries

There are two 12 volt batteries included providing power for the system. Each battery is a sealed Absorbed Glass Mat lead acid battery. The batteries are air transportable and sealed to eliminate leakage. Two of the batteries are used in series to provide 24 VDC to the hydraulic drive motor/pump assembly.

On-board Battery Charger

The onboard battery charger is a totally sealed computer regulated unit that monitors and charges each battery separately. The charger maintains the batteries in top condition by regulating the charging current. Powered with three-step automatic circuitry and onboard computer control, the TPRO220 shares a total of 20-amps. This unit is fully encapsulated, making it extremely vibration resistant and completely waterproof. It is designed to be connected indefinitely keeping batteries topped off.

Back Up DC Power Adapter

The system includes a receptacle that can be used to provide 28 volts power to the take up for continuous operation or as a backup to the batteries if they are not recharged.

Capstans and Pressure Roller Arms

The load is transmitted to the cable using two capstan drive rollers. Each roller is precisely sized to accommodate the cable and feeding it into the rotating tub. The capstans are made from a material that maintains high friction between the cable and the rollers, even if the cable is lubricated. The cable is held tight against the capstans by two pressure roller arms at the entry and exit tangent points where the cable makes contact.

The Hydraulic RHGSE can use either three or four groove Capstans, depending on the model purchased or if upgraded,

Standard Three Groove Capstans

For the three groove versions, the upper capstan and the lower capstans are made of different hardness material. The lower capstan is harder to react to the load and the upper capstan is softer to provide a good grip on the cable.

Optional Four Groove Capstans

The (optional) four groove versions use a stainless steel first groove and both upper and lower capstans use the same urethane material. The first groove takes the high loads and the remaining three grooves provide the grip to develop the load on the cable.

Lubridryer Assembly

The cable is cleaned, dried and can be lubricated using the Lubridryer. The Lubridryer includes replaceable pads that clean the wire and also can be used to provide lubrication to the cable. If the rotating tub has been filled with fresh water to wash the saline residue off the cable, compressed air from the onboard air compressor is fed to the Lubridryer to dry the cable as it is reeled back on the rescue hoist. The Lubridryer is equipped with an oil shut off valve in order to provide you the flexibility of starting or stopping the lubricant from being released.

Load, Length, and Speed Indicators

The load applied to the cable is indicated via a digital indicator that utilizes the signal from a load cell. The length and the speed of cable in the rotating drum are indicated via digital readouts that utilize the output signal of a magnetic encoder. The cable length indicator counts up to indicate the length of cable unreeled from the rescue hoist and down as the cable length exits the rotating drum.

Rotatub and Spooler

The cable is collected in a rotating tub and spooler system, which accommodates any rescue hook and bumper configuration.The incremental length of the cable as it reels off and on the capstans is fixed, while the incremental length of the cable as it lays up in the rotatub and spooler is variable. Therefore the rotatub position is compensated during reeling to accommodate the accumulated error in length. The rotatub can be filled with fresh water to rinse the saline residue off the cable as it rotates in the tub.

Hook Attachment Point

An eye bolt and nylon tether are included to allow applying a load to the rescue hook and the end of the cable. By lifting the front wheels of the RHGSE off the ground a 600 lbs. load is applied to the hook and cable.

Optional Accessories

ZGS-15000-3

Magnetic Rescue Hoist Cable Inspection System
NSN# 3950-01-580-1775

The cable structural integrity is measured using the MagSens head. The system requires a customer supplied laptop computer to interface with the system electronics via a USB cable to measure and record permanent records of the cable structural integrity.

ZGS-10487-3

Protective Cover used on the Hydraulic RHGSE with Work Platform (Top only, color black).
NSN# Not Assigned

The one-piece top protective cover is designed to protect the asset from moisture based corrosion; from sand, dust and microbe contaminate; from salt and sulfur-based pollutants; from Ultra Violet light degradation; and from the creation of microclimates under a cover that amplifies corrosion. The cover is soldier friendly to assure use and protection. This is defined as lightweight, packable, easily installed and removed in all weather extremes, field repairable and cleanable with soap and water.

ZGS-10457-1

Hydraulic RHGSE Work Platform
NSN# Not Assigned

The work platform is for use only with the Hydraulic RHGSE and was designed after it was observed that many hoist maintainers were standing on the hydraulic oil tank of the RHGSE, in order to reach the rescue hoist. The work platform was developed to allow the RHGSE to double as a working platform to work on the rescue hoist. It is a retrofittable kit that only requires match drilling four holes and the assembling of the platform to the RHGSE. The height of it allows easy access to external hoists on medium-lift helicopters such as the Black Hawk, NH90, or Bell -412.
