This Turbine Screw Lift acts as a high-precision vertical positioning station specifically engineered for the rigorous demands of the power generation and aerospace industries. Built by Gradin as a custom engineered-to-order (ETO) solution, the system utilizes synchronized mechanical screw-jack technology to ensure absolute zero-creep performance—maintaining its exact position under massive loads for extended durations without hydraulic drift. Designed for the assembly and maintenance of multi-ton turbine rotors and casings, this Turbine Screw Lift provides a stable, vibration-free interface for critical alignment tasks. Capable of handling extreme payloads with micron-level repeatability, it offers a mission-critical alternative to hydraulic systems in environments where precision, safety, and mechanical locking are non-negotiable requirements for successful assembly or MRO (Maintenance, Repair, and Overhaul) operations.

Mechanical Self-Locking and Zero-Drift Structural Integrity
Unlike hydraulic systems that are prone to pressure fluctuations and slow drift over time, the Gradin Bespoke Turbine Screw Lift utilizes mechanical worm gear technology to ensure absolute stability.
Axial Load Management: Every screw assembly is subjected to Finite Element Analysis (FEA) to simulate high-tonnage axial loads, ensuring the alloy steel screw maintains zero deflection.
Intrinsic Safety: The trapezoidal screw design provides an inherent self-locking mechanism, meaning the load stays locked in position even if power is lost, without the need for additional hydraulic check valves.
Long-Term Reliability: We utilize case-hardened worm gears and high-precision thrust bearings to ensure a zero-fatigue structural lifespan under high-frequency assembly cycles.
Precision Synchronization and High-Performance Drive Logic
Maintaining perfect synchronization between multiple lifting points is critical when handling oversized aerospace or energy components. The Gradin Bespoke Turbine Screw Lift utilizes advanced servo-driven synchronization logic.
Multi-Jack Coordination: We can link 2, 4, or 8 lifting jacks through mechanical line shafts or electronic Siemens PLC synchronization, ensuring the entire platform raises and lowers with sub-millimeter uniformity.
Soft-Start Precision: The integration of proportional speed control allows for ultra-smooth transitions, preventing any inertial “jerk” that could damage sensitive turbine blades or avionics.
Closed-Loop Feedback: High-resolution absolute encoders provide real-time data to the control system, allowing the lift to adjust its stroke with a precision of up to ±0.05mm.
Modular Interface and Adaptability to Extreme Environments
Modern industrial assembly requires equipment that can perform in specialized environments. Every Gradin Bespoke Turbine Screw Lift is designed with a modular interface tailored to your facility’s DNA.
Custom Tooling Interfaces: We customize the top mounting plates with integrated turntables, vacuum jigs, or specialized cradles bespoke to your specific workpiece geometry.
Harsh Environment Duty: For power plants or casting houses, we offer heat-resistant shielding and specialized lubricants designed for high-ambient temperatures.
Cleanroom Compatibility: Available with stainless steel housings and sealed bellows, ensuring that the precision lifting mechanism generates zero particulates in high-spec aerospace cleanroom environments.
[Energy & Power] – Industrial Turbine Maintenance and Alignment
O Gradin Bespoke Turbine Screw Lift is the premier professional choice for the power generation industry where aligning massive turbines with generators requires absolute stability.
The Challenge: Standard hydraulic lifts can “creep” over long maintenance hours, leading to structural misalignment during bolting.
Gradin Solution: Our screw lifts provide a zero-drift platform, allowing technicians to perform precision alignment tasks with the confidence that the heavy turbine remains frozen at the exact height required.
[Aerospace] – Satellite and Aircraft Jig Positioning
In aerospace manufacturing, handling high-value components requires extreme precision and cleanroom-grade vertical flow.
The Challenge: Positioning sensitive fuselage sections or satellite arrays where any sudden movement or hydraulic leak could result in catastrophic asset loss.
Gradin Solution: Engineered with sub-millimeter precision and mechanical self-locking, the Gradin screw lift provides a vibration-free vertical transition, docking perfectly with fixed assembly jigs every time.
[High-End Machinery] – Precision Mold and Die Adjustment
For heavy machinery manufacturers requiring the high-tonnage adjustment of dense, unbalanced molds.
The Challenge: Adjusting 50-ton molds with uneven centers of gravity where standard lifts might experience torsional deflection.
Gradin Solution: We utilize FEA-optimized multi-jack systems that synchronize power across the entire platform, ensuring the heavy mold is adjusted to the ergonomic assembly angle with total structural safety.
Redundant Safety Architecture and Precision Monitoring Logic
Safety in high-precision, high-tonnage vertical movement is our most critical engineering priority.
Fail-Safe Mechanicals: Beyond the self-locking screw, we integrate secondary safety nuts that take over the load in the rare event of a primary thread failure.
Active Perimeter Protection: Our systems are synchronized with Siemens safety-logic and perimeter laser scanners, ensuring that the lift executes a controlled stop if an operator enters the zone.
Real-Time Load Cells: Integrated load monitoring provides constant feedback on weight distribution, ensuring that the Gradin Bespoke Turbine Screw Lift protects your personnel and your facility assets throughout every precision cycle.
Para essa série para serviços pesados, podemos projetar capacidades de carga de até [300] toneladas, com dimensões de plataforma e alturas de elevação personalizadas de acordo com seu envelope operacional. Os requisitos que excederem nossa matriz de engenharia padrão serão submetidos a uma análise de elementos finitos (FEA) por nossa equipe de engenharia para garantir a viabilidade estrutural antes de propor uma solução.
Para iniciar a proposta de engenharia, forneça os seguintes dados de linha de base:
Capacidade de carga nominal
Altura máxima de elevação e altura fechada
Dimensões da plataforma (C x L)
Ciclo de trabalho (por exemplo, ciclos operacionais por hora/dia)

Restrições de profundidade do poço ou de espaço aéreo
Sim. Os sistemas de controle podem ser equipados com protocolos de comunicação padrão (por exemplo, Profinet, Modbus, Ethernet/IP) utilizando [Siemens / Allen-Bradley / Omron]. PLCs. Isso garante uma sincronização perfeita do sinal de E/S com transportadores upstream/downstream, unidades AGV/AMR e sua sala de controle central.
Toda unidade personalizada passa por um teste obrigatório de aceitação de fábrica (FAT) antes do envio. Isso inclui testes operacionais contínuos com carga nominal de 100%, testes de sobrecarga estática com [120% / 125%] e o acionamento físico de todas as travas de segurança mecânicas antiqueda e hidráulicas. A documentação FAT e a prova de vídeo estão incluídas em seu pacote de engenharia.
Após a aprovação final dos desenhos de arranjo geral (GA), o prazo de fabricação normalmente é de 4 a 8 semanas. Os componentes estruturais de grandes dimensões são projetados com um design modular para caber em contêineres de transporte padrão (20FT/40HQ). A montagem no local utiliza conexões de flange aparafusadas pré-projetadas e plugues de aviação para serviços pesados, eliminando rigorosamente a necessidade de soldagem em campo.
Fornecemos um padrão [12/24]-A garantia de um mês cobre a estrutura e os principais componentes hidráulicos/elétricos. Para minimizar o tempo de inatividade operacional, um conjunto abrangente de consumíveis padrão (por exemplo, kits de vedação de cilindros, interruptores de deslocamento, relés) é enviado junto com o equipamento. Durante o período de garantia, as peças de reposição para falhas não induzidas por humanos são enviadas por frete aéreo prioritário (DHL/FedEx) em 48 horas.
Além da garantia, garantimos suporte de engenharia vitalício. Os desenhos CAD, os esquemas elétricos e a lista de materiais (BOM) do seu equipamento personalizado são arquivados permanentemente em nosso sistema. Isso garante que você receba solução remota ininterrupta de problemas, orientação de manutenção e correspondência exata de peças de reposição durante todo o ciclo de vida do equipamento.
