Engine accelerator control unit of hydraulic type crane

摘要

(57) Abstract Objective As for this device, the hydraulic type credit which is loaded onto the track/truckIt is something regarding the engine accelerator control unit of n.As for control unit of engine accelerator of this genus, hydraulic type clayThe hydraulic change-over valve control lever 8 which controls the Drive of n - 11 8a - 11a, 8b - 11b forward above the specified quantity andTilt to converse direction, the operation conversion which possesses swinging arm 17bFeature through 17 and concatenated means 18, akuse of the engineIt had tried to transmit to rureba 6a. ButAnd others, as for accelerator lever 6of a engine, power of governorResisting the carriage return spring, because it is necessary to manipulate, virtueTilt control force of the work lever is difficult to manipulate largely the problem thatIt was. Constitution Operation convert feature akuserure of 17 and engine 6In concatenated means 18 where bar 6a is concatenated, pump oilway 12The servo cylinder 20 which designates oil pressure as power source the mediating/helping equipment is done,It is.
