Abstract
In the energy, the transportation, the metallurgy, the chemical industry,
the mine and other professions equipment setups, in the overhaul work, the
assembling and dismantling big specification bolt quite is difficult; Some bolts
install in the spatial extremely small and narrow place are unable with to
lengthen the arm of force or with the method fastening and the disassemblage
bolt which hammers; Some equipment long-term use in the quite moist place, the
bolt rusts away seriously is unable with the artificial disassemblage, thus
overhauls with difficulty; In elevated duct and on high altitude equipment
skeleton fastening and disassemblage bolt, staff although wears the safety belt
also with difficulty to use the strength, must safely complete the work to be
extremely difficult; According to the equipment management authoritative
organization statistics, has above 50% in the equipment movement breakdown is
because the bolt question causes, but creates the equipment significant accident
because of the bolt question the quantity also extremely astonishing, therefore
the new equipment setup and the overhaul standard fasten to the bolt the moment
of force request quite is strict, but meets the requirements with difficulty
with the artificial method.
Above the hydraulic pressure torque spanner solves the question ideal tool.
This tool the high-pressure oil which produces with the necessary ultrahigh
voltage hydraulic pump takes the power, automatically completes the bolt the
fastening and the disassemblage work, steady, does not have the impact, safe,
the assembly quality is high
