Self-aligning Welding Rotator For Pipe Heat Exchanger Welding And Positioning Equipment
Welding rotator is kind of our advanced welding equipment, which is be researched and manufactured absorbing domestic and international advanced equipment.
It is mainly used for pipe, containers, boilers, pressure vessels, oil tank and other cylinder's assembling, burnishing and welding.
There are two series of welding rotator, including self aligning rotator (HGZ), and conventional rotator (HGK).

The self-aligning welding rotator consists of two sets of main and auxiliary machines, namely, the active rotator and the passive rotator. Each group of the self-aligning series active and passive frame has four rollers. The rollers are made of an inner iron core and an outer polyurethane structure. Durable, no vibration during use.
The operation of the active rotator is driven by a speed-adjusting motor through two worm gearboxes synchronously, and a speed-adjusting controller is used to achieve stepless speed change. The mechanical transmission has low noise and stable rotation of the workpiece. Each group of rollers is automatically adjusted within a certain range of workpiece diameter, and the working range of each tonnage of the roller rack shall not exceed the maximum diameter.

Details of the electric control box:
This set of welding rotator used polyurethane wheels to increase the friction between the roller and the cylinder, so that the cylinder does not slip, and has the characteristics of wear resistance and high temperature resistance.
Features of self-aligning welding rotator :
1. The self-aligning welding rotator bracket automatically adjusts the angle of the roller bracket according to the diameter of the workpiece to meet the support and rotation drive of workpieces of different diameters.
2. Adopt frequency converter stepless speed regulation, wide speed regulation range, high precision and large starting torque.
3. Adopting high-capacity bearings, no tremor in rotation, and long service life.
4. Combined box-type base, with high rigidity and strong bearing capacity.
5. The specially designed grooved steel core polyurethane roller has high friction, long life and strong bearing capacity.
6. Advanced manufacturing technology, good straightness and parallelism of each shaft hole, minimizing the amount of movement of the workpiece caused by insufficient manufacturing precision.
Self-alinging Welding Rotator Application :
1. Marine , Oil&Gas ;
2. Offshore , Petro Chemical ;
3. Plate Heat Exchanger ;
4. Charged air cooler ;
5. Pressure Vessel ;
6. Boiler ;
7. Pipe system&Steel works etc.
The welding rotators have trolley tilting anti drift rotator. Accordingly this decive has advantages of compact structure, small cubage, beautiful shape, ligtweight, convenient operating and so on.
The machine can assort all kinds of auto welding or manual welding, improving welding quality, lessening welding labor and improve productivity. We can provide solutions to unique welding rotator according to the customer's requirement.
The welding rotator can use together with column and boom and SAW system to realize inside and outside girth and longitudinal welding.
Competitive Advantage:
1. All the bolt using 12.9 grade Bolt , not using 8.4 grade. Making the machine more stronger.
2. 20 % overweight design , could making the rotator focus more.
3. Double motors and reducers , and if the workpiece stress is different , could ensure the rotator working properly , and longer service life.
4. Double row wheels , not only making the wheels stable , but also artifacts to increase friction.
5. All the parts using well-known brands in China or other countries . Quality is more reliable .
6. Using double row bearings.

FAQ
1. What are the materials of the wheels?
Rubber, polyurethane or steel wheels.
2. What is the difference between conventional and self-aligning?
The conventional welding rotator requires the customer to manually adjust the distance of the rollers within the effective range of the equipment. It's a bit convenient, flexible, and low price.
The self-aligning welding rotator only needs to place the cylinder on the equipment, and there is no need for manual adjustment within the effective range of the equipment, but the price is higher than conventional.
3. What is included in one set of Welding Rotator ?
One set Welding Rotator include 1 drive roller & 1 idler roller, and 1 electrical cabinet with hand remote.
4. How to adjust the base of the conventional welding rotator ?
We have bolt adjustment and screw adjustment to choose from. If there is no special requirement, it will default to bolt adjustment.
5. Do you provide warranty?
We provide a 13-month warranty and can provide customers with technical guidance for life.
6. Replacement parts can provide it?
We provide it for free during the warranty period, and charge for it after the warranty period.
