Work Detail

Repair And Maintenance Services Of Cranes – Modernization Of Polar Bridge Cranes 5,6Uq00e01. Modernization Of Polar Bridge Cranes 5,6Uq00e01. The Public Order Includes: Design, Supply, Dismantling, Installation And Commissioning Of The Ksk Intended For Replacement (Structures, Systems And Components) And Design And Integration Of New Program Parts In The Control System Of The Polar Cranes. Main Functions Of The Project: • Replacement Of All Power Cables, Control And Control Cables And Communication Cables Of The Crane In The Controlled Area (From Hermetic Cable Glands To All Terminal Boxes, Actuators, Inductive Sensors, Encoders, Profibus Line Repeaters, Limit And Centrifugal Switches, Emergency Stops, Service Contacts, Lighting And Others); • Replacement Of All Electrical Devices (Limit Switches Of All Lifting Mechanisms, Trolleys And Bridge, Emergency Stops, Service Contacts, Sirens, Lighting And Others), Terminal Boxes And Cable Routes In The Controlled Area; • Replacement Of Electric Hoists I, Ii And Iii Mounted On Pc; • Replacement Of The Analog Speed Sensors Of The Dc Motors Of The Movement Mechanisms; • Replacement Of The Asynchronous Motors For The Movement Of The Hooks And Bolts Of The Lifts; • Replacement Of The Encoders For Determining The Spatial Coordinates Of The Lifts, Trolleys And The Bridge Of The Polar Cranes; • Replacement Of The Inductive Sensors For The End Positions Of The Lifting Bolts And For The Zero Positions Of The Bridge; • Replacement Of The S7-400 Industrial Logic Controller Of The Control System; • Replacement Of The Direct Current Regulators Siemens Simoreg Dc-Master Of The Mechanisms For The Movement Of The Polar Cranes; • Replacement Of The Decentralized Siemens Et200s Peripherals Of The Cabinets And Control Panels; • Replacement Of The Safety Modules Of The Control Cabinets; • Replacement Of The Operator Panel Siemens Pc670 On The Control Panel; • Replacement Of A Siemens Mp270 Service Panel On The Door Of A 96Sa1 System Control Cabinet; • Constructive Solution Against Chafing Of The Cables, During The Rotation Of The Crane, In The Bearing Node Of The Cable Route Above The Portal Of The Crane; • Constructive Solution For The Protection Of The Cables For Controlling The Bolts Of Lifts 320 T. And 160 T. Anti-Clamping And Tearing By The Rotating Mechanisms Of The Lifts; • In The Control System, It Should Be Possible To Register Load Cycles Of Lifts 320T., 160T., 2X70t, Hoists 1,2 And 3. According To Gost 33169 - 2014, Each Type Of Working Cycle Scheme Represents A Sequence Of Movements That Is Performed By A Specific Crane From The Beginning Of Lifting The Load Until The Moment When It Is Ready To Lift The Next Load. Each Operation Is A Loading Cycle Of The Polar Crane If It Includes The Following Three Stages: - Hooking The Load; - Work Progress (Moving The Load, Disconnecting); - Idling (Returning The Lifting Mechanism To Its Initial Position). • Replacement Of The Television System Of The Polar Cranes (Pc) For Visual Control Of Cargo Transport.
