The manual hydraulic stacker typically utilizes various mechanisms and controls to adjust fork width, height, length, and spacing. The specifics may vary depending on the specific model and manufacturer, but some common mechanisms and controls are as follows:
Fork Width Adjustment:
Screw Mechanism: The forks of the stacker may be attached to screw mechanisms that can be loosened or tightened to adjust the fork width. By rotating the screws, the space between the forks can be increased or decreased according to the required width.
Fork Height Adjustment:
Hydraulic Pump: The stacker is equipped with a hydraulic pump lever or handle that operates a hydraulic cylinder. By activating the lever, the forks can be raised or lowered to the desired height. Releasing the lever locks the forks in place at the adjusted height.
Height Indicator: Some stackers have integrated height indicators on the hydraulic cylinder, allowing the operator to easily gauge and adjust the fork height based on specific requirements.

Fork Length Adjustment:
Telescoping Mechanism: In certain stackers, the forks are designed to be telescopic, enabling adjustment of the fork length. This mechanism allows the forks to extend or retract, providing flexibility to handle loads of different lengths. Locking pins or latches are typically provided to secure the forks at the desired length.
Removable Extensions: Another method for adjusting fork length is using removable extensions. These extensions can be attached or detached from the standard forks, effectively extending or reducing their length as needed.
Spacing Adjustment:
Side Shifter: Some manual hydraulic stackers come equipped with a side shifter mechanism. This allows the operator to move the entire set of forks laterally, allowing for easier alignment with pallets or to accommodate varying load widths.
Fork Positioning Lock: In some stackers, there are preset spaces indicated on the fork carriage. The operator can manually adjust the fork position by moving it along the carriage and locking it in place at the desired spacing.
