ABSTRACT:
A hydraulic line attachment device is provided. The hydraulic line attachment device comprises a first assembly comprising a first frame constructed for holding a plurality of first hydraulic line couplers and a first coupling member; and a second assembly comprising a second frame constructed for holding a plurality of second hydraulic line couplers and a second coupling member constructed to engage the first coupling member and align the plurality of first hydraulic line couplers with the plurality of second hydraulic line couplers. At least one of the first coupling member and the second coupling member comprises an arm constructed to engage at least one of the first frame and the second frame and engage the other of the first coupling member and the second coupling member. The other of the first coupling member and the second coupling member comprises a cam that engages the arm to provide tightening of the first assembly relative to the second assembly. A method for using a hydraulic line attachment device is provided.
