Crowbar is a working tool, make heavy use of leverage to overcome the force of gravity, the weight lifted from the ground and displacement practices. Crowbar stick into hexagonal, round and flat pry bar. Hexagonal rod and round stick can be processed as follows: two circles, two flat or round a head a head flat, as construction tools or hardware tools, the latter can be used as a car lorry flat pry tool length is the thickness of the points, as most of the fill. Tire tool.
Generally divided into explosion crowbar and special crowbar. Material generally have 45 #, as well as beryllium and aluminum bronze alloy. Usually, we used mostly special crowbars, easy to use. When in use, the staff must be familiar with performance tools, features , use, storage and repair and maintenance methods. various construction tools must be formally qualified products manufacturers.
Crowbar used in many cases, for example in moving large equipment, repair, etc., is a common instrument of labor, is the use of leverage to make noon overcome gravity, the weight lifted from the ground and moved practices occur. Pry stick stick into hexagonal, round stick and flat stick.
Material: beryllium copper, aluminum bronze alloy of two, in which beryllium materials face hardness HRC35 ° or more, tensile strength δ b) 105-120kgf / mm2; aluminum bronze material face hardness HRC25 ° or more, the tensile strength δ b) 75-85kgf / mm2; and beryllium copper alloy explosion-proof tools and both magnetically shielded, there is a magnetic field in the working environment can be used normally flat shovel listen rods.
