The purpose of this course is to teach basic operation and maintenance of mobile hydraulic systems used on line trucks. The course presents the basic principles of hydraulic power and explains how these principles are used to produce motion. Inspection and routine maintenance of mobile hydraulic systems are also discussed.

At the conclusion of this course, participants should have a basic understanding of how mobile hydraulic systems operate. They should be able to identify components of a mobile hydraulic system and explain how they function. They should also be able to inspect a mobile hydraulic system and perform minor maintenance.

By the end of this course, you will be able to:

State the purpose of the mobile hydraulic system found on a typical line truck and describe the basic principles of operation of a mobile hydraulic system.

State three basic functions of hydraulic pumps. Describe the basic operation of a typical reciprocating pump and of a vane-type rotary actuator.

Identify the two basic types of hydraulic actuators and describe the basic operation of a single-acting linear actuator, a double-acting linear actuator and a vane-type rotary actuator.

State the basic function of hydraulic valves in mobile hydraulic systems and describe the basic operation of a flow control valve, a directional flow control valve, a check valve, and a relief valve.

Identify the parts of the mobile hydraulic system on a typical line truck and describe the operation of holding valves and dump valves in a line truck hydraulic system.

Explain why line trucks have two sets of controls that can be used to operate the bucket.

Describe a general procedure for conducting a pre-used inspection of a mobile hydraulic system.

Describe general procedures for changing hydraulic fluid, replacing a fluid filter, fixing a leaky fitting, and replacing a hydraulic hose on a line truck.
