B. EPT mechanism has severe placement restrict with rotary switch.
C. EPT mechanism has CLZ EPT couplings crane and trolley vacation system is CL and CLZ sort.
3.2.2 Trolley vacation system
Trolley is individual driving variety. Wheel is double rim type and bumper is EPT type.
three.2.3 EPTT vacation mechanism
EPTT is four-EPT sort, and wheel has double rims .EPTT shell is angle form. Bumper is EPT anti-crash variety.
three.three Important elements
3.three.one JCEP motor is YZP series with rated volt of 380 v and 50Hz, insulation diploma is F grade and protecting quality is IP44.This kind of motor has greater in excess of load potential and mechanical toughness and is ideal to equipments which start off and end often or with over load and apparent vibration and crash.
three.three.2 Brake is YWZ series with EPT typical closed thruster, elevate system has guide release system. Brake has continual characteristics, EPTTer use daily life and simplicity of routine maintenance JCEP in GB6333-86.
three.3.3 EPTT has ZQ variety and ZSC kind JCEP in ZBJ19571.
3.three.four EPTT hook is forged materials JCEP by GB699-sixty five and GB1051.
3.three.five EPT substance is EPTT150 forged JCEP by ZBJ80006-87 and ratio of pulley and metal wire is no considerably less than 22.4.
3.three.six Winding drum is EPTT200 cast JCEP by ZBJ80007-87
3.three.7 Steel wire of 6w(19) type is JCEP by GB1102-seventy four with power within 1400~1700N/mm2.JCEPty aspect from five to seven must be applied according to system course.
three.three.8 Wheels established stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd is GB4628-84 and wheel substance isZG50SiMn.Tread hardness is within HB300 and HB 380 and a lot more than HB260 in depth of 20mm.
3.3.9 EPT of brake wheel in elevate system is #forty five steel at lEPT in GB699.Brake wheel surface area hardness is inside of EPTC45 and EPTC 5 5,and EPTC40 in depth of 2mm.
3.3.ten EPT of significant elements this kind of as major girEPTTand conclude beam and trolley body meet stXiHu (West EPT) Dis.Hu (West EPT) Dis.rds of GB700-88 and GB1591-88 as follows.

four EPTT major craftsmanship
4.1 Uncooked content with quality certificates is checked just before coming into manufacturing facility warehouse. Then random chemical-actual physical take a look at need to be carried out before storage in warehouse.
four.two Metal plate and EPT metal need to be shot blasted to achieve quality Sa2.five for metal plate area and quality S3 for EPT metal. Rust should be taken out by making use of primer paint.
four.3 Refer to far more thorough info for major factors (primary girEPTTand end beam) approach artwork
A. EPTT plate and world wide web plate butt weld ought to be submerged arc welding. Steel plate more than 10mm thick need to be groove welding and weld should be extremely-sonic or x-ray non-problems 100% inspected.
B. EPTT plate and world wide web plate slicing is with numerical managed cut EPTT to receive pre-deflection.
C. EPTTitudinal seam of principal girEPTTand end beam is welded with submerged arc welEPTTor micro-controlled protecting carbon dioXiHu (West EPT) Dis.de EPT.
D. EPT and assembly of bridge construction are completed with massive measurement system and amount welding.
five Purposeful features
five.1 EPTT static rigidity: for class A4-A6 crane with trolley and load in girEPTTmiddle situation, rigidity is significantly less than s/800,for class A7 crane with trolley and load in girEPTTmiddle position, rigidity is significantly less than s/one thousand.
Static test: crane is loaded with one.25Gn and 100mm-200mm above ground for far more than 10 minutes. Soon after load is released, principal girEPTTshould have no permanent deformation in three check cycles.
5.two EPTT tests: trolley is loaded with 1.1 Gn to start off and brake inside of travel distance of each motion for at lEPT one hour. Then, there should be no injury and linkage free in all factors and system.
six Protecting features
6.1 In EPTT distribution protecting system, there are main circuit breaker, main contactor and automatic swap in every mechanism. Distribution control has crane EPTT activation and off switch and emergency swap, EPTT resource index, protection switch and limit change. Major loop has circuit shortening, in excess of load security, volt loss security and zero security.
six.2 Restrict change of LX10-31 shall minimize off EPTT offer in hoist system when hook approaches intense stage.
6.three There are vacation limit switches at finishes of travel mechanisms.
6.4 There are also QCX-2 type overload limiter which has sign and acoustic-optic alarm and more than load controls.
seven JCEPty defense
seven.1 Emergency switches in control loop circuit shall cut off loop EPTT source in circumstance of unexpected emergency.
seven.2 EPTT entrance doorway and inclining stair doorway and fence door are all interlocked and have protection switches. When 1 doorway is open, security switch is off and then principal contactor shall be disconnected instantly.
eight Trolley EPTT provide
Trolley EPTT is provided through suspending comfortable cable unEPTTEPT steel.
nine Illumination and sign
9.one There are separated transformer for signal and illumination. EPT input line volt is 380 V and aux. output line volts are 220V and 36V. 220V is for crane illumination EPTT and 36V is for crane sign and restore EPTT.
9.2 EPTs unEPTTgirEPTTare quake resistant 400w sort.
nine.3 EPTT have start off warning system controlled from operator cabin.
nine.four EPTT have repair and check socket of AC 36V.
10 Other folks
ten.1 EPTTs are arranged in raceway, and gentle tube is utilized the place raceway is impossible to reach.
10.2 EPTTs are higher temperature proof and EPT is much more than 1.5mm2.
10.3 EPTT reception panel and control panel lines of diverse mechanisms use copper wire and copper bars.
ten.4 There is ten%~fifteen% inventory allowance in handle panel cable bus and EPTT distribution panel and wiring box terminal.
10.5 Primary loop contactor in manage panels of diverse mechanisms are both EPTly and mechanically interlocked.
