とを特徴とする緩衝装置付吊具。 A roughly U-shaped upper support member with internal cushioning rubber is suspended on both sides of the horizontally arranged upper frame.
The lower support member in the shape of a letter intersects with the upper support member on the upper surface of the buffer rubber, and below the upper support member, both sides of the lower frame parallel to the upper frame are connected to the lower support member, and the piston rod is connected to the lower frame. A hydraulic cylinder protruding downward is fixed to the upper center of the lower frame, and a variable throttle valve is used to separate the cylinder upper chamber formed in the cylinder head cover section and the cylinder lower chamber formed in the rod cover section with the piston as a boundary. A suspension with a shock absorbing device characterized in that the piston is provided with a check valve that communicates with piping having a piping and allows free flow from the upper chamber of the cylinder to the lower chamber of the cylinder, and lifts the upper frame by applying a load to the tip of the piston rod. Ingredients.
