Chapter Hydraulic pumps one Outline of the hoist There are enormous relations between development and national economic construction of the engineering machinery. In the past two years,
the country Hydraulic motors--->hydraulics parts and local project investment source of engineering construction have presented the pluralistic development trend, government
investment, local investment, World Bank's loan, consortium, private capital,etc. have offered the good external environment condition for
development of engineering machinery.
Total introduction hoist comes at first
1.Working characteristic of tool instrument of 3 hoists
First .
the same time of sport of several different directions, the technological difficulty is relatively great.
Two. It is varied to hang the heavy object transported, the load is changed. Some heavy objects weigh up to more than one hundred tons, volume
is loud and irregular, there is scattered one, hot to merge flammable and explosive dangerous cargo,etc., enable and hang the course of
transporting complicatedly and dangerously.
Three. Need to run in larger range, the activity space is relatively great, once cause the accident, the area influenced is relatively large too.
Four. Some hoisting machinery needs to carry personnel and doing the movement of hoisting or lower directly, its dependability influences the
personal security directly.
1.The main parameters of 4 hoist tool instruments
The main parameter of the hoist includes: Amount get up weight Gn, span S, range L, get up, rise degrees of H, running speed V, get up gravity
square
Main component of the hoist
1. Steel construction: Girder, end roof beam (crossbeam) Small frame, prop up leg, lay crossbeam, jack-up arm, equilibrate arm, post, door
shelf, pull rod, body of the tower, walk platform and cab,etc..
2.Actuator: Get up, rise organization, operate organization, go back, transform, construct, become pieces of organization and carry, rise
organization,etc..
3.Electric system: Handheld controller, make controller, conductive device, cable reel, resistance box, frequency converter and switch board,etc.
mainly.
4.Jack-up part: Hang 30 jin, crab bucket, jack-up electro-magnet, steel wire rope, ring chain, pulley, reel, brake, wheel and track,etc..
5.Safety device: Location device of high limit of rising, operate the terminal limit location device, bumper, anchor load with frank inserting
railing Hydraulics Parts---->Kato genuine cranes parts device or windproof iron shoes, security 30 jin, incline device, get up weight limiter, moment limiter and defend, collide device,etc.
prevent from, definitely.
