Abstract
The present disclosure provides embodiments directed towards a method and a system for fine control of hydraulic cranes. In one embodiment, a system is provided. The system includes a service pack having an engine. The engine has an operating speed ranging from a low speed to a high speed, a hydraulic pump coupled to the engine, wherein the hydraulic pump is configured to supply a hydraulic output to a hydraulic load, and a control system configured to control the hydraulic output. The control system includes a fine control mode configured to lock the engine in the low speed and control the hydraulic output in proportion to a percentage of a trigger activation.
