EASE OF USE QUESTIONS
How much does the Crawler weight?
The Crawler weighs approx. 90 lbs. And can usually be carried by one worker.
How long does it take to set up the Crawler?
First time set-up takes about 15 minutes to install 2 brackets. Subsequent mounting/dismounting takes 5 minutes.
When the Crawler is attached, can the scaffold be used without a drill?
Yes, the Crawler’s floating drive wheel will lock in an up position in seconds and pushing the scaffold by hand is easy.
How long will the Crawler operate on one battery charge?
The larger the voltage and Amp Hr. of the battery associated with the drill, the longer running time. For example, the DeWalt 20 volt drill with a 4 AH Lithium Ion battery will operate the Crawler approx. 2,450 feet. Most drills come with two batteries, so while one is being used in the Crawler the other battery can be charging, allowing continuous use of the Crawler. click here.
By adding the Crawler to a scaffold, does this limit the possible platform locations?
No, the Crawler’s mounting brackets attach to the horizontal rungs of the scaffold’s end frame. Most scaffold trusses attach to the vertical post of the scaffold frame.

The Crawler, when completely extended will allow the operator to comfortably stand at an elevated platform height of approx. 7 feet, allowing an approx. 14′ working height.
Will the Crawler fit though a man door or into an elevator?
Yes, the Crawler will compress to a total height of 79” allowing it to pass through a door opening without removing it from the scaffold.
Does the Crawler’s weight count against the scaffold load?
The addition of the Crawler to a scaffold does not alter the weight limit set by the manufacturer of the scaffold. Because of the floating drive wheel, the pressure on the drive assembly remains constant regardless of the gross weight of the scaffold. The weight of the scaffold is not transferred to the drive wheel.
Can the Crawler adjust to various platform height?
Yes, The crawler can adjust to fit scaffolds from five feet to nine feet six inches in height.
