Abstract
A hydraulic chain clamp apparatus for pipe sleeves for a pipe. The apparatus includes a clamping chain circumnavigating the sleeves and the pipe, the chain having a first end and an opposed second end. The apparatus includes a housing block with a chain lock mechanism securing the first end of the chain to the housing block. A hydraulic cylinder mechanism is connected to the housing block. The hydraulic cylinder mechanism is attached to the second end of the chain and is adapted to move the chain between a tightened, closed position and a loose, open position.
