Abstract:
1. A hydraulic line attachment device comprising: (a) a first assembly comprising a first frame, a plurality of first hydraulic line couplers, and a first coupling member; (b) a second assembly comprising a second frame, a plurality of second hydraulic line couplers, and a second coupling member; (c) the plurality of first hydraulic line couplers and the plurality of second hydraulic line couplers are constructed so that they are closed to flow of hydraulic fluid therethrough when disengaged, and open to flow of hydraulic fluid therethrough when engaged; (d) at least one of the first coupling member and the second coupling member comprises a shaft, the shaft being constructed to engage the other of the first coupling member and the second coupling member, and wherein the other of the first coupling member and the second coupling member comprises a cylinder, wherein the cylinder engages the shaft so that as a result of rotation between the shaft and the cylinder, the plurality of first hydraulic line couplers and the plurality of second hydraulic line couplers are engaged or are disengaged depending on the direction of rotation; (e) wherein the shaft comprises a first pin and a second pin extending therefrom, and the cylinder comprises a first spiral track constructed to receive the first pin and a second spiral track constructed to receive the second pin, and wherein the first spiral track comprises a first groove in the cylinder and the second spiral track comprises a second groove in the cylinder so that the first pin engages the first groove and the second pin engages the second groove; and (f) a handle coupled to one of the first coupling member or the second coupling member so that moving the handle causes engagement and disengagement of the plurality of first hydraulic line couplers and the plurality of second hydraulic line couplers.
