This video goes over several tips and techniques for using ground ladders. This is a video that's good for anyone who uses ladders on a daily or regular basis, not just firefighters.
MFA training video on 24-foot ladder,single person low shoulder carry & raise technique. Once raised to the desired height, the ladder is rotated 180 degrees so that it is in the proper climbing position (fly out.) The climbing angle is then adjusted and the halyard secured.
From the revitalization of historic structures to the arrival of fresh ideas to familiar places, this year's crop of newcomers stand out for their ingenuity.
DIY video of making the universal 1 2 3 blocks. A2 tool steel setup blocks designed by Robin Renzetti. These blocks are truly universal and can be connected in nearly any configuration. We take a look at some of the machining operations to make them. Its a must have tool in every machine shop.
Given two batteries, it chooses the one to connect to the load based on the voltage measured at their poles. It can also be used to switch DC power supplies. The circuit we are proposing is an automatic battery switch made with power MOSFETs with very low RdsON, which are specifically for SMD.
