从China供应商批量进口Adjustable Welding Rotator

Wuxi Zhonghao Machinery Manufacturing Co. Ltd. produces an adjustable welding rotator series that uses reserved threaded holes or screw rods to regulate the centre distance of roller chains, accommodating diameter changes in cylindrical workpieces. The complete set comprises a driving rolls carrier and follower rolls carrier, with roller structures available as steel-glue combination, polyurethane, all-steel, and other variants. The equipment employs AC variable frequency speed regulation, which the supplier states improves operational reliability. The HGK series spans models from HGK2 (2,000 kg capacity) to HGK1000 (1,000,000 kg capacity), with vessel diameter ranges from 250 mm to 9,000 mm depending on specification.

The roller specifications vary across the model range: rubber roller diameters and widths range from 200 mm by 80 mm on the HGK2 to 1,000 mm by 1,000 mm on the HGK1000, with corresponding metal roller dimensions from 190 mm by 16 mm to 1,000 mm by 1,000 mm. Motor power per driving set ranges from 0.18 kW on the smallest model to 17.5 kW on the HGK1000. The standard linear speed across all listed models is 6-60 m/h, a typical range for circumferential welding applications using submerged arc, MIG/MAG, or flux-cored processes. The steel-glue combination roller and polyurethane variants protect vessel surfaces from damage during rotation, while all-steel rollers handle higher point loads on heavy-wall fabrications.

These rotators serve welding, polishing, rubber lining, and assembly operations in pressure vessel fabrication, tank manufacturing, pipe production, and heavy engineering. The AC variable frequency drive provides smooth start/stop characteristics and speed hold stability. Buyers should note that while the specification table lists maximum load weights and suitable vessel diameters for each model, actual selection requires matching the vessel's centre of gravity position, shell roundness, and surface condition against the roller contact pattern and linear load capacity. Custom turning-roll carrier types are available on request for non-standard geometries or integration with automated welding systems.

Wuxi Zhonghao Machinery Manufacturing Co. Ltd. is based in Huishan District, Wuxi, Jiangsu Province, China, with postal code 214156. The company operates within the Wuxi industrial cluster, an area known for metalworking machinery and welding equipment production. The supplier carries a 'harbor' trust tier designation. The recorded response rate is 0.00% with zero average response hours, which may indicate limited active engagement through the platform messaging system or outdated metrics. Buyers should attempt direct contact via the supplier's official channels and consider requesting a voice or video call to establish communication reliability.

The source profile provides no information regarding the year of establishment, registered capital, factory floor area, number of employees, annual turnover, export markets, or specific client references. No certifications such as ISO 9001, ISO 14001, or CE marking are mentioned. The supplier's product range focuses on welding rotators and turning-roll carriers, with explicit capability to customise designs per customer demand. The detailed specification table covering 15 models from 2,000 kg to 1,000,000 kg capacity suggests substantial manufacturing scale and experience in heavy-load material handling equipment. Buyers should independently verify production capability, quality control procedures, and after-sales support infrastructure before placing orders.
