A "Squishy" tire can CERTAINLY make one tip. Try driving your vehicle with a low tire and see how "unpredictable" it becomes!

Re: 50' Boom Falls Over


I'm guessing it was the curb too.

I worked out of a similar unit all year last year and had in some precarious situations but didn't even come close to tipping it, he must have really been working at it.

Re: 50' Boom Falls Over


After taking a closer look at the video that thing is not up 50'. You figure a traffic lane at maybe 12'. So two lanes and the sidewalk. Doesn't seem like 50'.

How wide are the roads you travel?

But YES, far from 50' of extension.

Re: 50' Boom Falls Over


I think 12' is the normal traffic lane on a highway. Most interstates are sized to accomadate 102". Considering it is a center city street and there aren't any wide shoulders in that video either.

Re: 50' Boom Falls Over


Lucky to be alive.

A few years back I was in one and the front tire found a sink hole. The only thing that keep us from hitting the ground was the side of the building we hit. Makes it hard to get back in one.

I always lanyard up when in the man lift.

But in the back of my head I'm thinking "possible human trebuchet"

Some guys get way to used to driving them while up in the air, and get careless. Glad he wasn't hurt worse or killed. That must be one wild ride down!

Re: 50' Boom Falls Over


the counterweight on the turntable is turned over the side of the machine.
The extendable axles appear to not be extended.
The unit has safety circuits that will not let the boom elevate if the axles are not extended.
sometimes safety circuits are overridden to accommodate site conditions...
NEVER a smart move!

Re: 50' Boom Falls Over


wow, I'm glad he survived. Curious to find out what caused it to tip to avoid a situation like this.

I do not believe a S-85 genie has extendable axles on it.

Re: 50' Boom Falls Over


Looks to me the axles weren't extended I have the same machine there is supposed to be a safety device that won't let the boom go up more than 15 ft if the axles aren't extendedl

Re: 50' Boom Falls Over


true crocop,
Randy, the newer S85s do not have extending axles.
The older ones, like the one that tipped over, definitely need to have the axles extended.
The newer model has a link assembly that keeps the weight of the boom over the center of the machine.
The older models needed the axles extended to provide the stability.

I just looked this up on Genies site , and the unit starting with ser # 00001 could have been built either way. The with ones also acording to parts book shows lift cyls to extend with I don,t see in the picture.

there have been a few changes on this model throughout it's evolution.

Up through serial # 3081 there were hydraulic jacks on the chassis to lift the wheels off the ground so the axles could be extended.

Serial numbers 3082 through S8008-7999 do not have the hydraulic jacks on the chassis. The axles were extended by holding the Axle Extend switch while driving the machine forward or reverse.

From serial # S8008-8000 (S80) and serial # S8508-8001 (S85) there are no extending axles on the current production machines.
