SIS7200A vs SIS5120A Reel Storage Trolley Choice | Southern Machinery

SIS7200A and SIS5120A are SMT intelligent reel storage trolleys from Southern Machinery. The SIS7200A is a 7-layer stainless steel unit for storage and recording, holding 1,400 7-inch reels. The SIS5120A is a 5-layer unit built for transport, holding 600 7-inch reels or 300 13-inch reels.

Why do reel storage trolley decisions go wrong?

Most teams choose by capacity alone. Then the trolley meant to hold material becomes the one that has to move it, or the reverse. The source data separates the two models by function: the SIS7200A is listed for storage and recording, while the SIS5120A is listed for transport.

The hidden problem is that material flow is rarely one-dimensional. Reels must rest somewhere, be tracked, and then travel to the line. If one trolley is asked to do both, either floor space or handling effort suffers.

What is a simple framework for choosing between the two?

Use three questions in order.

1. Does this unit mainly store, or mainly move?

Per the source, SIS7200A = storage and recording; SIS5120A = transport. Start here before looking at capacity.

2. Which reel size dominates?

The SIS7200A is specified at 1,400 7-inch reels, with capacity flexibly adjusted in width. The SIS5120A is specified at 600 7-inch reels or 300 13-inch reels. If your lines use many 13-inch reels, check the second figure, not the first.

3. Does the floor plan fit the footprint?

| Parameter | SIS7200A | SIS5120A |

|---|---|---|

| Weight | 115 kg | 60 kg |

| Material | Stainless Steel | Stainless Steel |

| Size | 21304002000 mm | 13204001630 mm |

| Layers | 7 layers | 5 layers |

| Capacity | 1,400 7-inch reels | 600 7-inch reels or 300 13-inch reels |

| Power | AC 220V 0.075kW | DC 5V 0.06kW |

| Network | wired and wireless | wired and wireless |

| Function | storage and recording | transport |

Both units list wired and wireless network, so either can connect to a tracking workflow. Integration details on the software side are not specified in the source — contact Southern Machinery to confirm.

How do the two models work together on a line?

A practical pairing is one SIS7200A as the recorded home for reels and one or more SIS5120A units as the carriers that bring reels toward feeders. This pairing is our planning suggestion, not a configuration stated in the source; confirm it with the factory.

Upstream and downstream, reel handling sits next to the rest of the line: THT machines, board handling systems and inspection equipment. See also auto insertion solutions.

What does it cost in time? A simple ROI formula

Searching for a reel is a recurring labor cost. Use this formula with your own numbers:

Annual saving = (minutes saved per search x searches per day x working days) / 60 x hourly labor cost

Example only, depending on configuration: 5 minutes x 40 searches x 250 days / 60 = about 833 hours. Multiply by your own hourly cost. These inputs are illustrative, not source data, and any result is subject to final technical confirmation. No ROI is guaranteed.

What support comes with the equipment?

The source lists worldwide support, free installation and training, 1-day lead time for spare parts, and a 1-month customized solution. Southern Machinery was founded in Shenzhen, China in 2011, serves 237+ global customers, and supplies SMT/THT PCB assembly automation including wave soldering, board handling, and inspection.
