Why Grip Replacement Doesn't Have to Mean a Full Rebuild

Field-replaceable grips aren’t standard.

OTTO has made them an exclusive, optional feature on select models, and it changes what a grip failure actually costs you.

What field replaceability actually changes

On a standard grip or joystick/grip assembly, replacement usually means replacing the whole thing. It’s built as a single unit and wired throughout the machine, so a technician has to remove the entire assembly to service any part of it.

OTTO’s field-replaceable models are built differently. The faceplate or the grip can be removed and swapped on its own, using a limited number of tools. OTTO says the swap doesn’t need a technician either: someone without technical training can do it in a matter of minutes.

In practice, that means:

●        Improved serviceability

●        Fast grip or faceplate swaps in the field

●        Optional feature on select OTTO grips

●        Ideal for high-abuse applications

Field replaceability itself is something you specify when you order the grip or joystick/grip assembly.

The advantage over a standard grip

For machine builders and OEMs, that difference, pulling out just the failed part instead of the whole grip and joystick assembly, plays out at the exact moment it matters most: when something’s already gone wrong and the machine is down.

●        No need to pull the entire grip and joystick assembly, just the part that’s failed

●        The termination stays identical on swap-out, so there’s no system redesign to work through

●        Less time on tools per repair, and less cost per callout

●        A non-field-replaceable assembly means the same job takes longer and costs more, every time

Which OTTO grips it applies to

Field replaceability isn’t a blanket feature. It’s specific to certain models, and it works differently depending on which part of the grip is designed to come off.

Field-replaceable faceplates are optional on the G3-A and G3-B grips. Their faceplates are mounted on their own screws, independent of the grip handle, so they come off without disturbing the rest of the grip.

Field-replaceable grips are the G3-C and G3-M models. These are assembled as a single unit designed so the entire grip can be removed in one piece.

The same options carry through to complete joystick/grip assemblies built around these grips: HJMG3-A, HJMG3-B, HJLG3-A and HJLG3-B for field-replaceable faceplates, and HJMG3-C, HJMG3-M, HJLG3-C and HJLG3-M for field-replaceable grips.

Where it earns its keep

Any machine can benefit from this, but some applications get more out of it than others.

Open cabs and equipment in vandal-prone areas see grip damage more often than most. If your fleet already runs a high rate of grip replacement because of the environment or how hard it’s used, field replaceability is built for exactly that problem: less repair time, lower cost, every time it happens.

It also buys you room to change your mind later. The switches you specify on a grip faceplate today might not be the ones you need in twelve months. Without field replaceability, that usually means ripping out the whole grip to start again. With it, you can update the faceplate, or move to a grip with different functions such as Grip Touch operator sensing or a trigger on the handle, without redesigning the rest of the control system.

Worth specifying at the design stage

Because field replaceability is specified when the grip or joystick/grip assembly is ordered, it’s worth raising at the design stage rather than leaving until later.

If you’re speccing operator grips into your next build, particularly for equipment that sees hard use or open-cab exposure, talk to the Switches Plus team about which OTTO models give you this option.
