Dual-Size ISO Tank Rotator, Fits Both 20ft and 40ft Tanks, PLC Automatic Positioning for Welding & Cleaning

This universal PLC-programmable ISO tank rotator is a newly upgraded multi-functional intelligent turning machine designed specifically for mixed production and maintenance of 20ft and 40ft standard ISO tank containers. Breaking the traditional limitation that one rotator can only match one tank size, this innovative model adopts an adjustable sliding base and flexible locking support structure, enabling a single machine to perfectly adapt to both 20-foot and 40-foot tank containers. It completely solves the problems of high equipment investment, large floor occupation and complicated workshop layout caused by purchasing two separate rotators.

Equipped with an industrial PLC intelligent control system and high-precision encoder positioning technology, the equipment delivers fully automated 360° continuous rotation, arbitrary angle preset, fixed-position precise stop and automatic cycle operation. It completely replaces traditional manual button control and crane flipping work, eliminating positioning errors, tank shaking, surface scratching and low working efficiency caused by human operation.

Whether for new tank manufacturing circumferential welding, accessory assembly, internal residue deep cleaning, external rust removal and paint spraying, weld nondestructive testing, tightness inspection, or old tank overall overhaul and refurbishment, this universal rotator provides stable, accurate and repeatable turning support.

It is the most cost-effective and high-efficiency core equipment for modern ISO tank factories, chemical container maintenance yards, tank cleaning service companies and pressure vessel inspection institutions that handle both 20ft and 40ft tank container business.

This universal tank rotator is fully compatible with all standard 20ft and 40ft international ISO tank containers, supporting empty tank, semi-load and full-load heavy-duty working conditions.

• True Universal Dual-Size Design (20ft + 40ft, One Machine): The adjustable sliding base structure enables free switching between the two mainstream tank sizes, eliminating the need for two independent rotators. It greatly reduces equipment investment cost and saves workshop floor area.
• Intelligent PLC Unattended Automatic Operation: Programmable angle rotation and automatic cycle work reduce manual operation frequency, eliminate human error, greatly improve production efficiency and ensure uniform processing quality of each tank.
• Ultra-Stable Full-Load Heavy-Duty Performance: Stress-relieved rigid steel frame plus full gear heavy-torque drive structure ensure stable, jitter-free operation under maximum load, meeting high-standard precision welding and flaw detection requirements.
• Full Protection for Tank Surface & Structure: Soft rubber roller contact avoids metal scratching, paint damage and frame deformation, effectively reducing tank rework rate and maintenance cost.
• Dual Modes with Free Switching, Wide Adaptability: Intelligent automatic mode for mass batch production and manual jog mode for personalized overhaul and special-position processing, perfectly adapting to diversified workshop needs.
• Stepless Variable Speed for All Working Processes: Precise low speed for inspection and fine work, stable medium speed for large-area processing — fully covering welding, cleaning, painting, detection and overhaul procedures.
• Durable Structure & Low Maintenance: Heavy industrial structure with few wearing parts, stable performance, long service life and low daily maintenance cost. No complicated foundation installation required — easy to place and use.

This universal PLC automatic tank rotator is widely applicable to international standard ISO tank container manufacturing factories, chemical liquid tank professional maintenance centers, food sanitary tank refurbishment workshops, petroleum container service yards, large-scale tank deep cleaning companies and pressure vessel nondestructive testing institutions.

It is suitable for all 20ft and 40ft standard ISO tanks used for chemical raw materials, edible oil, industrial powder, fuel oil and cryogenic medium transportation. It covers full-process operations such as new tank circumferential welding, structural assembly, internal residue cleaning, external rust removal and repainting, weld nondestructive testing, sealing leakage inspection and overall tank overhaul calibration.

All tank rotators pass strict multi-item full-performance factory tests before delivery, including a 24-hour full-load continuous rotation test, 20ft/40ft size switching test, PLC automatic cycle operation test, positioning accuracy calibration test, gear meshing stability test and full safety protection function test.

We provide complete English operation manuals, touch screen operation guides, professional installation drawings and electrical schematic diagrams, as well as remote video commissioning and technical training services.

We support personalized customization of load capacity, rotation speed, support span and control program logic according to customer workshop environment and special tank specifications. Lifelong technical support and global after-sales service ensure long-term stable and high-efficiency operation of customer equipment.
