Saimo belt weigher servicing

This page is for anyone searching for someone to service, repair or calibrate their Saimo scales. If you have a Saimo unit on a conveyor and you want an independent set of hands on it, read on, then give us a call.

Do you service Saimo belt weighers?

We do, and we do the whole scale, not just the box on the wall. That covers:

• Saimo weigh frames and the frame mechanicals (pivots, tie rods, mounting)
• Saimo integrators, including the 6101
• Load cells and their wiring back to the integrator
• Speed sensors feeding the integrator, including the N60 and other pickup types
• Full calibrations, including zero, span and material comparison where warranted
• Fault-finding, repairs and spare part supply for ageing units

We’re independent, so we’re not tied to one brand’s product line. We supply parts for Saimo and the other major belt weigher brands: a genuine part where it’s available, or a suitable alternative, with compatibility confirmed and the part identified on the quote. A great deal of Saimo equipment runs reliably on Australian conveyors, and sites want to keep those units going rather than replace a scale that still does its job.

What Saimo equipment do we see in the field?

Saimo Technology Co., Ltd is a Chinese manufacturer of belt weighers and conveyor instrumentation, based in Xuzhou. Its gear is used in coal handling, power, steel, cement and ports, and it turns up on Australian coal chains, at bulk export terminals, and on mine and quarry conveyors. The units we most commonly work on are:

• The 6101 integrator, part of Saimo's 6000 series in panel and field-mount versions, which turns the load and speed signals into a rate and a running total
• The N60 speed sensor used on Saimo belt scale systems, mounted on the tail pulley or a return idler

We also see Saimo conveyor protection switches installed alongside their scales, so we often look after the whole Saimo package on a transfer point rather than a scale in isolation.

What is distinctive about servicing Saimo scales?

A Saimo scale weighs material the same way every other belt weigher does, so most of the work is the same disciplined approach we bring to any integrator. We record the as-found settings before we change anything, confirm what type of speed input the integrator is expecting before we connect a sensor to it, and check the load cell signals are clean and balanced across the frame.

Where we earn our place is the mixed site. We work from what the unit is actually doing on the day, its live readings and its wiring, and we look after the Saimo scales alongside everything else on the plant.

What does a Saimo calibration look like?

Work on or near a conveyor, or inside an electrical enclosure, needs isolation under your site’s procedures and trained, authorised people. If that’s not you, stop and call us on 1300 101 666.

At a practical level, a routine maintenance calibration on a Saimo scale runs the same shape as any belt weigher:

1. Zero the scale on a clean, empty belt run over whole belt revolutions, so any variation around the belt loop averages out.
2. Span the scale against a known reference, such as a static test weight or a chain equivalent applied to the frame.
3. Material comparison where it is warranted and practical, checking the totalised weight against a known trucked or weighbridge figure.

We record as-found figures before we change anything and as-left figures after, so there is a clear before-and-after for the site. Those figures, the integrator's configuration and what we found go into AIMM, our asset management system, so every Saimo scale we look after has a permanent record and a due date you can see, at no extra cost. This is routine maintenance calibration to keep the scale reading true for day-to-day production accounting, and it is not a legal-for-trade or NMI trade verification, which is a separate, regulated activity. For the detail on each method, see our guide to belt weigher calibration methods.

What goes wrong on Saimo scales?

Most faults on a Saimo scale are the same faults that affect any belt weigher, and they usually sit in the mechanicals and the field wiring rather than the integrator:

• Material build-up on the belt, idlers or the weigh frame, which quietly shifts the zero
• Speed sensor wear or slippage, especially on wet or dusty belts and where a pickup wheel or bearing is seizing
• Junction box moisture and corrosion, a frequent cause of intermittent or lost signals
• Loose terminals worked free by conveyor vibration over time

For the wider picture on these, see our guide to common belt weigher faults, and for anything speed sensor related, see the belt weigher speed sensor guide.

Why use an independent for a mixed-brand site?

Very few sites run one brand of scale. It is common to have Saimo on some conveyors, Thermo Ramsey on others, and Schenck or another brand elsewhere, often all installed at different times by different people. As an independent, multi-brand service company, we look after the lot with one team of service technicians and one point of contact. That means fewer separate call-outs, one consistent set of records across your scales, and a technician who already knows the quirks of each brand's integrator rather than learning yours on the day.

Need a manual for your equipment?

On imported equipment the paperwork often travels with the unit, so the supplier or contractor who commissioned it may hold the copy that matches your conveyor.

Talk to us about manuals for your equipment. Send the make, model, serial number and software version (a photo of the label is fine) and we’ll help you find the right document.
