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.
