  • Pile driver

    serch.it?q=Pile-driver

    A pile driver is a device used to drive piles (poles) into soil to provide foundation support for buildings or other structures. The term is also used in reference to members of the construction crew that work with pile-driving rigs. One type of pile driver uses a weight placed between guides so that it can slide vertically. It is placed above a pile (pole). The weight is raised, which may involve the use of hydraulics, steam, diesel, or manual labour. When the weight reaches its highest point it is released, and hits the pile, driving it into the ground.

  • Hydraulic rescue tools

    serch.it?q=Hydraulic-rescue-tools

    Hydraulic rescue tools are used by emergency rescue personnel to assist vehicle extrication of crash victims, as well as other rescues from small spaces. These tools include cutters, spreaders, and rams. Such devices were first used in 1963 as a tool to free race car drivers from their vehicles after crashes. Hydraulic rescue tools are powered by a hydraulic pump, which can be hand-, foot-, or engine-powered, or even built into the tool. These tools may be either single-acting, where hydraulic pressure will only move the cylinder in one direction, and the return to starting position is accomplished using a pressure-relief valve and spring setup, or dual-acting, in which hydraulic pressure is used to both open and close the hydraulic cylinder. Recently, manufacturers of these rescue tools have begun offering options for electrically-powered versions as well using simple electric rotation motors or screw pistons rather than the aforementioned setup, promising greater reliability, lower cost of ownership, lower weight and better handling, greater portability, quicker and more direct operation, and greater potential power.
