Overview
Ergonomic pallet handling keeps heavy pallets moving between conveyor levels without manual lifting. The machine in the footage below is a pallet lift/transfer unit: a loaded pallet enters on a lower level, the platform raises it to an upper level, and the upper conveyor carries it out, so the load changes height in a smooth automatic pass. This guide explains the lift’s place in a line, what to specify, and how to verify it before acceptance. It is written for plant engineers and line planners who move loaded pallets between conveyor heights.
Why Lift the Pallet By Machine
Raising loaded pallets by hand strains operators and slows the line. A floor lifter changes the pallet level in a smooth vertical pass, so:
| Before (manual) | After (floor lifter) |
|---|---|
| Operators lift or pry pallets between levels | A platform lift does the height change in one pass |
| Missed heights cause product damage | Load stays flat and level throughout |
| Line pace depends on operator strength | Line keeps its speed; one pallet at a time |
| Strain injuries accumulate | Operators are moved to control and supervision |
How the Floor Lifter Works
| Element | What it does |
|---|---|
| Lower feed conveyor | Brings the pallet into the lift at the incoming level. |
| Lifting platform | Raises the loaded pallet to the target height in a guided vertical pass. |
| Upper outfeed conveyor | Carries the pallet away at the higher level. |
| Position sensors | Tell the PLC the pallet is seated before the platform moves. |
| Safety guarding | Interlocked access keeps operators clear of the travel area. |
Lift height, pallet size and load weight are project inputs confirmed per project.
How the Lifter Hands Off to a Wrapper
On the integrated configuration, the floor lifter does not end the line: it raises the pallet to wrapper height so the load continues into an automatic orbital wrapper (the manufacturer’s Yellow Jacket wrapper equipment class) without being set down by hand. The hand-off is made by the line control and mechanical interface, and these are the elements to confirm:
| Interface element | What to specify |
|---|---|
| Roller alignment | Infeed and outfeed roller spacing match the pallet bearers so the transfer stays level. |
| Photo-eye release | A sensor confirms the pallet is fully on the wrapper infeed before the conveyor is released. |
| Height match | The raised lift height equals the wrapper infeed height, so there is no manual re-lift at the seam. |
| Interlocking | The lift and wrapper share an emergency-stop and interlock chain; neither moves while an operator is inside the guarded area. |
| PLC hand-off | The lift signals “pallet in place” and the wrapper starts only on that signal. |
What to Specify
| Input | Why it matters |
|---|---|
| Pallet size and load weight | Sets platform dimensions and lifting rating. |
| Lower and upper levels | Sets lift travel and stroke time. |
| Cycle time | Sets drive and speed. |
| Conveyor type and width | Sets infeed/outfeed integration. |
| PLC protocol | Sets the hand-off, photo-eye release and interlock signals to the wrapper. |
| Environment | Sets drive/coating (indoor, dust, wash-down). |
Factory Testing and Acceptance
- Full-lift evidence. A test log of complete raise/lower passes with a representative load.
- Extended run. The vendor’s stated practice on this family includes near-continuous pre-delivery testing (up to about 24 hours where stated).
- Control and safety. Smooth, responsive control; emergency stop verified; interlocked guarding checked.
- Level pass. Proof the pallet stayed level through the lift with no drop or tilt.
- Commissioning. Written installation, commissioning and on-site service scope.
- Pallet Stretch Wrapping: Operation and Applications – Palletized loads on similar line integration.
- Coil Upender & Industrial Turnover Solutions – Pallet and load handling equipment in the same family.
- How 180° Turning Machines Work for Precast Components and Sheets – EN 415-10 / ISO 12100 reference notes.
On arrival repeat: empty pass, loaded pass, emergency stop.
FAQ
Q: Is this the same as a scissor lift?
A: Functionally similar (level change) but built into the conveyor flow; the lift height and load rating are sized to the line rather than to a workbench.
Q: Can it change conveyor direction, not just height?
A: The height lift changes level; direction changes happen in separate transfer units. State what the line needs when specifying.
Q: What safety standards apply?
A: The machine family is designed with EN 415-10 as the machinery safety reference and an ISO 12100 risk assessment for the lifting travel.
Next Step
Send pallet size and load weight, the lower and upper levels, cycle time and conveyor layout so the floor lifter is sized and placed on the line drawing.
