0.8x1m Galvanized Reciprocating Lift | 6m High-Efficiency Vertical Transfer Galvanized Reciprocating Lift | 6m High-Efficiency Vertical Transfer
Überblick über das Projekt
This project addressed the need for automated, efficient, and reliable material transfer between different production floor levels or workstations at varying heights.
The core equipment is a reciprocating lift with a platform size of 800mm (W) x 1000mm (D) and a maximum lifting height of 6 meters. The lift features galvanized treatment, providing excellent rust and corrosion resistance, particularly suited for industrial environments.
Its critical function is to achieve precise and smooth material handover with roller conveyors at the same or target level, enabling continuous, automated material flow. This eliminates manual handling bottlenecks and enhances production efficiency and logistics automation.

Die Herausforderung
- Precise Integration: The lift platform must achieve exact height alignment and horizontal position (±3mm) with the roller conveyor at any stopping point within its 6-meter travel range, especially at the handover height. Any deviation risks material jamming, dropping, or conveyor damage.
- Significant Height & Stability: The 6-meter height necessitates exceptional structural rigidity and stability throughout operation, particularly at the top and bottom positions, to prevent swaying that could compromise integration accuracy and operational safety.
- Cycle Efficiency: The “reciprocating” nature requires the lift to quickly and smoothly return to the origin or next demand position after completing a transfer cycle to meet continuous production line cycle times. Optimizing the cycle path and control logic was key.
- Environmental Suitability: Industrial environments often involve dust, humidity, or mild corrosive elements, demanding robust equipment durability and protection.
- Safety Compliance: Comprehensive safety measures (light curtains, guarding, fall arrest devices) were essential in the vertical travel and horizontal transfer zones to protect personnel and equipment.
- Signal Interfacing: Reliable communication (material presence, lift request, transfer permission, status, faults) between the lift and upstream/downstream roller conveyors was crucial for coordinated, collision-free material flow.
Lösungen
- Precision Guidance & Drive System: Utilized a high-rigidity mast structure (e.g., square tube or heavy-duty guide rails) with precision guidance components (linear guides or heavy-duty guide rollers) to ensure smooth, vibration-free platform travel over 6 meters. Employed high-precision servo motors or encoder-feedback VFD systems for closed-loop position control, guaranteeing the required ±3mm positioning accuracy.
- Adjustable Interface Design: Incorporated height-adjustable guide rails or transition plates on the lift platform edges to ensure smooth height and horizontal alignment with the roller conveyor. The conveyor interface featured correspondingly adjustable supports.
- Optimized Cycle Control Logic: The PLC control system intelligently planned optimal travel paths (e.g., nearest call, sequential order) based on demand signals (from different levels or upstream equipment), optimizing acceleration/deceleration profiles for fast, smooth cycling and maximizing equipment utilization.
- Galvanized Anti-Corrosion Treatment: Key metal components (main frame, platform) underwent hot-dip galvanizing or electro-galvanizing, significantly enhancing corrosion resistance, wear resistance, and lifespan for industrial environments.
- Multi-Layer Safety System: Implemented comprehensive safety light curtains (access points, platform periphery), emergency stops, mechanical fall arrest devices (safety brakes), platform overload protection, upper/lower limit switches, and necessary safety guarding. All safety signals were integrated into the PLC safety circuit.
- Standardized Communication Interface: Employed Industrial Ethernet (e.g., PROFINET, EtherNet/IP) or standard I/O signals (24VDC) for reliable communication with the PLC/MES systems of the roller conveyors, facilitating exchange of material presence, lift requests, status, and fault signals.
