Large Four-Column Lifting Platform for Nuclear Industry – High-Precision Heavy-Duty Solution

Project Overview

This large four-column lifting platform is specifically engineered for the nuclear energy industry, designed for training and simulation operations during nuclear reactor refurbishment, particularly for heavy pipe replacement tasks.

It meets extremely stringent precision requirements and complies with nuclear industry quality standards, reflecting top-tier engineering and manufacturing capabilities.

Basic Parameters

ParameterValue
Main Platform Size9.4m × 7.5m
Front Extension9.4m × 2m
Maximum LoadApprox. 52,200 kg
Lifting TravelApprox. 7m
High-Speed Mode2.3 m/min
Low-Speed Mode0.15 m/min
Drive SystemServo Motor + Ball Screw + Bevel Gear
Safety FeaturesGuardrails, Fall Arrest System, Ladder

How It Works

The platform utilizes four independent ball screw and bevel gear mechanisms, driven by servo motors with electronic synchronization control to ensure smooth and stable lifting. It offers both high-speed and low-speed operation modes, along with a dual braking system and fall protection devices, providing safety and reliability during heavy-load and precision operations.

The Challenge

Maintenance and pipe replacement in nuclear reactors require equipment with exceptional safety, precision, and load-bearing capacity. Conventional platforms often fail to provide sufficient space, lifting stability, and precision while meeting strict nuclear industry standards.

Solutions

A large platform with a front extension offering ample operating space;

A four-column structure with ball screw drive ensuring stability under heavy loads;

Multi-speed operation and electronic synchronization for adaptable workflow;

Comprehensive safety mechanisms including guardrails, dual braking, and fall protection.
