Product Description

Product Introduction 

Welding rotator with idler rolls has strong load-bearing capacity and high stability. It can support workpieces of 1T-800T (such as large pressure vessels and wind turbine towers) to avoid the safety risk of hoisting and flipping. All rollers are rubber-wrapped or steel-made, which can effectively prevent the surface of the cylinder from being scratched and reduce the vibration or deviation during rotation. The welding rotator manufactured by Wuxi Lemar has a self-locking function, which can not only rotate the cylinder evenly, but also serve eccentric vessels and tanks.

Application scenarios
Circumferential welding: butt joint of storage tanks, boilers, and pipelines.Longitudinal welding: Rotary support during segmented welding of cylinders.Overlay/repair: Overlay welding of workpieces such as rolls and gears.

The use of welding rotator with idler rolls avoids manual handling.

By adjusting the roller spacing or height, it can adapt to workpieces of different diameters and meet different process requirements (such as low speed for argon arc welding and high speed for submerged arc welding). 

It can also be linked with welding robots or automatic welding machines to achieve intelligent production (such as spiral pipe welding).

Daily maintenance:

Regularly lubricate moving parts such as bearings and gears, and use high-temperature resistant grease (such as high working temperature).

Clean welding slag and iron filings on the roller frame to keep the equipment clean.

Key Structure

Driving wheel group: motor drive (usually variable frequency speed regulating motor), control speed (such as 0.1-1.2m/min).

Driven idler wheel group: follow-up support, reduce friction resistance.

Frame and base: steel structure welding, need to mark the load bearing (such as 10-50 tons) and material (such as Q235B or Q355B).

Use in conjunction: Motorized welding rotator is the main welding auxiliary equipment, often used in conjunction with column and boom welding manipulator, and different welding power sources (Submerged arc welding machine, TIG MIG, or MAG, Laser) are selected according to the welding process requirements of pipes tanks to complete the straight seam welding or circumferential seam welding of the cylinder.

Workpiece parameters: diameter, length, weight (such as diameter Φ300-4000mm, weight ≤50 tons).
Drive mode: single driving wheel/double driving wheel, select according to load.
Additional functions: whether to need linkage welding trolley, automatic tracking of welds, etc.

FAQ

Q: What are the main types of Welding rotator with idler rolls ?

A:Manual adjustable roller rack: manually adjust the roller height through a handle or screw.

Electric adjustable roller rack: driven by a motor, suitable for heavy or frequent adjustment scenarios.

Combined roller rack: multiple roller racks are used in combination to support extra-long workpieces.

Q:How to choose a suitable screw adjustable Welding roller bed rotator?

A:The following factors should be considered:

Workpiece weight: The rated load of the roller frame must be greater than the weight of the workpiece.

Workpiece diameter range: Make sure the roller height can be adjusted to the required range.

Drive mode: Manual (economical) vs. electric (efficient).

Roller material: Rubber (anti-slip) or steel (wear-resistant).

Q:Can the adjustable roller bed be used for non-cylindrical workpieces?

A:Not recommended. The roller rotator is designed for cylindrical objects, and irregular shapes may cause rotation imbalance or equipment damage.

Q: What's the lead time for orders?
A: Standard models ship in 15–30 days; customized units require 30–45 days.

Q: Do you provide after-sales service overseas?
A: Yes, we have partnered service centers in key regions.

Q: Can I request a customized bucket size?
A: Absolutely! We offer tailored attachments.

Q: What documents do you provide for export?
A: Full export package (Commercial Invoice, Packing List, Bill of Lading, COC, etc.).

Q: How do I place an order?
A: Contact us via email/phone for a quote, then confirm with a PO.
