Remotely releasable coupler and hose retrieval mechanism for airbrake system

In a motor truck tractor for transporting a trailer having a pressure fluid operated brake system:

• at least one flexible pressure fluid conduit connected to a source of pressure fluid for conducting same between said tractor and a trailer;
• a coupler connected to said at least one flexible conduit for coupling said at least one flexible conduit to a filling connected to said trailer;
• a pressure fluid actuated retrieval mechanism having a boom mounted for movement on said tractor connected to said at least one flexible conduit for retrieving said coupler away from said fitting;
• a pressure fluid actuator connected between said boom and a predetermined point on said tractor for extending and retracting said boom with respect to said trailer;
• and
• a control system for operating said retrieval mechanism including a control valve operable to be actuated by an operator of said tractor to supply pressure fluid to effect operation of said pressure fluid actuator to retract said at least one flexible conduit and said coupler to a storage position.

In a motor truck tractor for transporting a trailer having a pressure fluid operated brake system:

• two flexible pressure fluid conduits connected to a source of pressure fluid for conducting same between said tractor and a trailer;
• a remotely releasable coupler for coupling each of said conduits to a respective fitting connected to said trailer;
• a retrieval mechanism connected to said flexible conduits for retrieving said coupler away from said fitting and wherein said flexible conduits are supported by said retrieval mechanism;
• a control system for operating said retrieval mechanism and said couplers including a control valve operable to be actuated by an operator of said tractor to supply pressure fluid to effect actuation of an actuator for said retrieval mechanism and for said couplers to release said couplers from said fittings and retract to a storage position.
