Abstract
The submarine working equipment illustrated which may be a diver's auxiliary equipment includes a hollow body that is specially reinforced against bending moments and pressure forces acting upon it by means of structure defining flow channels, for driving elements, that angularly penetrate it and by means of pressure chambers supported in the body which are adapted to multiple uses. The equipment is held and supplied with power by a connecting and supply cable. A main grab on the forward end of the body is adjustable to facilitate clamping on a wide range of diameters the clamping of the equipment on pipes, wracks, etc. so firmly that the equipment itself or working arms mounted thereon (tool arms, auxiliary grabs, platforms etc.) are capable of taking substantial working loads despite the small dimensions of the equipment. Control instruments and the driving elements permit the equipment to be used in a particularly efficient and safe manner both as a vehicle for mobile equipment and as tool machine or energy base for auxiliary machines in submarine operations with or without a diver's presence. The equipment can be quickly and reliably adapted to changing working conditions by easy replacement of modularly interchangeable supplementary equipment.
