Should I go with an individual or centralized power pack?

Every hydraulic stacker needs a power pack to generate lifting pressure. The question is whether each unit should have its own dedicated power pack, or whether one larger unit should distribute hydraulic pressure through shared lines to multiple stackers.

The right solution depends on project priorities such as redundancy, maintenance access, space planning, and system efficiency.

From the APS 2PK6.0 product data sheet, these base electrical specs per unit apply to each individual stacker unit.

The truth about power requirements.

Individual power packs do not require more total electrical power. The difference is how the same power is distributed, and what keeps running when one unit fails.

The Misconception

Myth

Individual power packs require more total electrical power.

Truth

Both systems draw the same total power from the grid. The real difference is how power is routed.

Operational Reality

Only enough lifts need to run at one time to serve the attendants on duty. Design power distribution around active use, not the total lift count.

Key Takeaway

Individual power packs provide greater reliability, easier maintenance, cleaner installation, and lower long-term risk.
