The Components of the Recovery System

OPEN LIFT BAG

These are open, balloon-like lift bags with a stop point. The shape of an inverted water droplet provides maximum lifting power with low weight. The force is distributed uniformly over the entire surface.

The shell material is made of high strength nylon fabric with polyurethane coating, providing maximum abrasion resistance. The shell is resistant to UV irradiation and most petrochemicals. The lifting straps are made of a resin-reinforced nylon fabric with a nominal capacity of 2700 kg (safety factor of 6:1). A patented push-button release valve with rip-cord function at the apex of the lift bag allows buoyancy control of the lift bag from above, from the sides, or from below. It is filled with a ¾-inch ball valve. Lift bags are open from 500 kg to 35,000 available.

CLOSED LIFT BAGS

When object must be brought as close to the surface as possible, the closed lifting bags from Subvalve USA are the ideal tools. This lift bag can handle any situation and aids in recovery of "standing" or "lying" objects, “inside” or “outside” objects, vehicles such as automobiles, water vessels, small airplanes or ROVs. The use of a lifting cushion reduces not only the strain put on conventional lifting equipment, but also the required operating time by divers.

Enclosed lifting bags from weights of 100 kg to 3000 kg are also sold.

The different attachment points allow flexibility in positioning the lifting cushion. The shell material is made of high strength nylon fabric with polyurethane coating which provides maximum abrasion resistance, and is resistant to UV irradiation as well as the most petrochemicals. The lifting straps are made of a resin-reinforced nylon fabric with a nominal capacity of 2700 kg ( featuring safety factor of 6:1). The lifting bags have a ¾-inch fill and vent valve. Accordingly, pressure relief valves (set at 0.172 bar / 2.5 psi pressure) are mounted to provide for safe ascent with enough outflow for the expanding air. A wide range of accessories complement the system and make it safer for the user.

CLOSED RECOVERY PONTOONS

Completely sealed, cylindrical body lifts are ideal for work in shallow waters. Whether used for recovery or underwater construction, laying cable or pipelines - U.S. Subvalve recovery pontoons are the tool of choice.

The shell material is made of high strength nylon fabric with polyurethane coating, providing maximum abrasion resistance and resistance to UV irradiation and most petrochemicals. The lifting straps are made of a resin-reinforced nylon fabric with a nominal capacity of 2700 kg (safety factor of 6:1). The end of the lifting points are fitted with shackles. A ¾-inch-fill valve and a 1 ½-inch exhaust valve are also standard, according to the size of the mounted pressure relief valves (set at 0.172 bar / 2.5 psi pressure). A wide range of accessories complement the system and make it safer for the user.

VEHICLE LIFTING SYSTEM VRS 2000 AND VRS 4000

The Subvalve U.S. automotive lift systems VRS 2000 and VRS 4000 are the only independent vehicle lifting systems that exist today. Over 20 years of experience in manufacturing and intensive cooperation with the forces of water police, fire-fighters and countless other aid organizations, the VRS-lifting devices have made use of systems to peak performance. Every feature of the VRS has been optimized for maximum portability and rapid deployment point.

The shell material is made of high strength nylon fabric with polyurethane coating provides maximum abrasion resistance, is resistant to UV irradiation, and the most petro-chemicals. The VRS 2000 is designed for cars and small boats, the VRS 4000 for vans, SUVs and vans. Each of the two lifting bags is a set with a zipper pocket for receiving a compressed air cylinder of 12 liters (diameter 171 mm). Compressed air cylinders are connected by means of either high pressure DIN R5/8-300 bar hoses or INT connections (see accessories). A stainless steel anchor point at each corner of the pillow allows use in any position. Two attachment points on the underside of the lifting cushion with a 1 meter long steel chain with snap hook are standard. The attachment points of the chains are separated by approximately 1 meter. The VRS can be quickly and easily connected to the front and rear axles or bumpers of most vehicles. A direct connection of the respective chains underneath the vehicle is an alternative method to raise a vehicle.
Each set includes a two lifting bags, individually wrapped in carry bags.
