The structure of hydraulic cylinders are various, and their classification methods are also various: according to the movement mode, it can be divided into linear reciprocating motion  and rotary swing hydraulic cylinder; according to the action of hydraulic pressure, it can be divided into single-acting hydraulic cylinder and double-acting hydraulic cylinder; according to the structure form, it can be divided into piston hydraulic cylinder, plunger hydraulic cylinder, multi-stage telescopic sleeve hydraulic cylinder, gear rack hydraulic cylinder and so on.

The piston type hydraulic cylinder can be divided into two types: single-acting and double-acting hydraulic cylinders. There are two kinds of fixing methods: cylinder block fixing and piston rod fixing. According to the action of hydraulic pressure, there are single-acting and double-acting. In a single-acting hydraulic cylinder, the pressure oil is supplied to only one chamber of the cylinder, and the cylinder moves unilaterally by hydraulic force, while the reverse movement is realized by external force (such as spring force, self-weight or external load), while the motion of the piston of the double-acting hydraulic cylinder is accomplished by alternating two chambers and by hydraulic force.

Single rod double acting piston hydraulic cylinder only has piston rod on one side of the piston, so the effective area of the two chambers is different. When the fuel supply is the same, the piston moves at different speeds in different chambers, and when the load to be overcome is the same, the pressure to be supplied in different chambers is different, or after the system pressure is adjusted, the load to be overcome in two directions of the hydraulic cylinder of the sanitation garbage truck is different.
