The Safety Clamp consists of individual links, flexibly hinged together.
The ‘T’-Type Safety Clamp help guard against dropping flush-joint pipe, tool strings, stream-lined drill collars, etc. into the hole while making/ breaking the tool string. These clamps are ideal as an emergency elevator shoulder for lifting items which have no shoulders for attaching conventional elevators.
The Safety Clamp consists of individual links, flexibly hinged together. Each link has a separate tapered slip which acts as a gripping member, much like a tapered rotary slip, and each slip is held in a retracted position on the taper by spring tension. When the clamp is tightened, each small slip takes a firm initial grip on the surface of the pipe. Should the pipe start to slip/ fall, or should any load increase occur against the slips, the taper mounting causes each slip to wedge tighter against the surface of the pipe to increase the grip or lock the pipe against further movement.
Gripping pressure is always uniform around the pipe so there is little chance of crushing thin-walled pipe or damaging the surface of the pipe. And since each link, complete with tapered slip, is interchangeable as a unit, the Safety Clamp is readily adaptable to virtually any diameter. Each link changes the effective gripping diameter of the clamp. All parts are made of alloy steel, heat-treated for strength and gripping ability.
The ‘T’-Type Safety Clamp is designed for small diameter pipe, 1-1/8” – 4-1/2” OD. Each link changes the effective working range approximately 1” in diameter. For sizes larger than 4-1/2” OD, the ‘C’-Type Safety Clamp must be used.
