R&M hoist, variable speed and OLI: when technology works for your productivity — and your safety

For a long time, an overhead crane was simple: you press a button, it goes up, it goes down, it moves forward. Efficient, but not always optimal. Today, the equipment that Protech distributes and installs incorporates technologies that tangibly change the reality on the factory floor—fewer shocks, less wear and tear, fewer accidents, and productivity that is measured at the end of the shift. Here are three of these technologies that deserve a closer look.

R&M hoists: reliability proven over time

R&M is one of the most reputable hoist manufacturers in America and has a global presence, and it's no coincidence that Protech has been an official distributor for many years. What distinguishes an R&M hoist in the field is first and foremost its mechanical construction: precision components, gears machined to tight tolerances, and a modular design that simplifies maintenance.

In practice, this translates into two important things for a plant manager: extended lifespan even under intensive use, and reduced downtime when maintenance is required. Parts are standardized, readily available, and a Protech technician knows them inside and out. For continuous production, this is just as important a factor as the initial purchase price.

Variable speed: less shock, more precision

A fixed-speed hoist works. But it slams on loads at startup, puts stress on the structure with every sudden stop, and requires a highly skilled operator for delicate positioning. Variable speed—via an integrated frequency inverter—eliminates this problem at its source.

The start-up is gradual, the stop is controlled, and the operator can bring a load within millimeters of its target without stress. The advantages are tangible:

• Less mechanical wear on brakes, cables and load-bearing structures

• Reduced shock to loads — particularly important for machined parts, molds, or fragile equipment

• Better long-term productivity , because a confident operator is an efficient operator

• Extended lifespan of the complete equipment

For applications in welding, machining or finished product handling, variable speed is no longer a luxury — it is a sensible engineering decision.

OLI (Overhead Lifting Monitoring): monitor your hoist before it speaks to you itself

The OLI ( Overhead Lifting Monitoring ) system is an integrated monitoring system for R&M hoists that continuously records and analyzes equipment usage data. Simply put: your hoist keeps its own logbook and alerts you when something needs attention before it becomes a problem.

Specifically, the OLI monitors critical parameters: number of lifting cycles, loads lifted, operating hours, and usage level relative to the device's service class. This data determines whether your hoist is being used within its designed limits—or if actual floor conditions have changed since purchase.

For a factory manager or maintenance manager, the benefits are direct:

• Maintenance based on actual usage , not an arbitrary schedule — we intervene when necessary, not just because six months have passed.

• Early detection of overuse — if your production has increased and your hoist is approaching its class limits, you'll know before it breaks down

• Automated documentation for periodic inspections and CSA-B167 compliance — the data is there, tracked, without any extra effort from your team

• Reducing unplanned downtime — the number one enemy of any production line

In a context where inspection standards are tightening and where the traceability of lifting equipment is becoming an increasingly frequent requirement, OLI transforms your hoist into an intelligently managed asset.

What this means for your operation

These three technologies—the mechanical reliability of an R&M hoist, the smooth operation of a variable-speed drive, and the intelligence of the OLI system—are not luxury options reserved for large accounts. They are applicable to a wide range of projects, and Protech can advise you on the combination that best suits your needs: the type of loads you handle, your frequency of use, your budget, and your long-term objectives.

For 30 years, we haven't just sold equipment — we've configured systems that work for you long after they're put into service.
