To address issues commonly encountered with traditional spring-loaded welding booms—such as diminished spring force, reduced balancing performance and insufficient stability during use—Xutai Machinery has independently developed a balancer system. This system utilises reinforced steel wire and high-strength materials, offering excellent toughness and superior fatigue resistance, ensuring it remains resistant to slackening and deformation even after prolonged repetitive use.

The optimised spring system maintains balanced load distribution across the boom, enabling smooth hovering and seamless lifting and lowering, thereby reducing equipment sway and enhancing the precision of welding operations. Furthermore, the two-section boom structure, combined with a 320° horizontal rotation capability, provides the equipment with greater workstation coverage, further boosting welding production efficiency.

● 5 meters two-section arm structure

Featuring a two-section arm design, the total arm length reaches 5 meters, providing a wider working range and meeting the requirements of large workpieces and wide-span welding stations.

● High-strength spring balancing system

Equipped with a proprietary balancing system manufactured from high-strength spring materials, it offers precise rebound and stable operation, with minimal risk of fatigue or deformation even after prolonged use.

● Multi-angle rotation operation

The wire feeder arm can rotate horizontally through 320°, whilst the connection between the main arm and the column supports 180° rotation, allowing flexible coverage of a wider range of welding areas.

● Compatible with barrel welding wire

Supports the use of barrel welding wire, reducing the frequency of welding wire spool changes and meeting the demands of prolonged continuous welding production.

● 15kg load-bearing wire feeder bracket

The high-strength wire feeder bracket is designed with a rated load capacity of 15kg, providing stable support for the wire feeder and associated welding cables.

● Reduced labour intensity

The wire feeder, welding cables and gas hoses are managed via a centralised suspension system, eliminating the need for frequent equipment handling and reducing labour intensity.

● Enhanced welding efficiency

Optimised equipment layout reduces auxiliary operation time, improving welding continuity and overall production efficiency.

The SPT-505 spring welding boom supports two mounting methods: column-mounted and beam-mounted, allowing for flexible selection based on workshop structural conditions and actual production requirements.

● The column-mounted installation utilises an independent column support structure, eliminating the need to rely on the workshop’s steel beams and allowing for flexible planning of the welding work area;

● Steel beam mounting involves securing the equipment to the workshop’s steel beams or steel structure, making full use of overhead space and reducing floor space requirements. This is suitable for welding workshops with limited space, narrow aisles or where floor installation is impractical.

Regardless of the installation method chosen, the SPT-505 spring welding boom maintains stable operation and fully utilises the wide coverage provided by its 5-metre two-section boom, offering enterprises an efficient and labour-saving welding support solution.

● Xutai Machinery’s welding booms are finished using a pure electrostatic powder coating process.

● We are available in a range of colors including yellow, orange and green.

● Should you require any other colors, simply provide the relevant colour code and we will produce them to your specifications.

How is the load-bearing capacity of the SPT-505 spring welding boom tested?

1. Static load test (most critical)

Install the SPT-505 spring welding boom in position, attach the standard weight assembly, and apply loads in stages from the rated load to 1.25 times the rated load to 1.5 times the rated load, allowing the structure to stand for 10–30 minutes.

Observation: No plastic deformation, no cracks in the welds, no structural deformation, and no abnormal noises.

If none of the above conditions are observed after 30 minutes, the product is deemed compliant.

2. Dynamic Test

The SPT-505 spring welding boom is repeatedly raised and lowered under the rated load, with the main boom rotating 180° and the wire feeder arm rotating 320°, and subjected to start-stop cycles. The test checks for any vibration, looseness or fatigue cracks. If none of the above issues occur during one hour of dynamic testing, the product is deemed compliant.

Once the static and dynamic tests have met the required standards, the quality control department will affix labels and stamp the product with a certificate of conformity, authorising its release to the market.

The Xutai Machinery SPT-505 spring welding boom is widely used in:

● Construction machinery manufacturing

● Steel structure fabrication

● Automotive and component manufacturing

● Shipbuilding

● Pressure vessel production

● Rail transport equipment manufacturing

● Heavy machinery manufacturing

Whether for large-scale welding stations or mass production lines, the system can be customised to meet specific requirements.
