Robust Roller Beds for Welding Automation
ESAB has launched a range of roller beds, designed to withstand harsh conditions and to help improve productivity and quality of round fabrications such as wind turbine towers, pipelines and vessels. Customers have an extensive choice of roller beds, with sizes and features to suit a broad array of applications. All of ESAB's roller beds can be used in conjunction with ESAB's A2-A6 process controller PEK system for submerged arc welding, GMAW welding and arc gouging.
Depending on the model selected, the maximum load capacity ranges from 2.5 to 60 tons per section and the roller beds can handle component diameters from approximately 150mm to 8.4m. For relatively simple applications, the CD 5-120 and CI 5-120 are conventional roller beds (driven and idler types), with features such as rollers with durable polyurethane tyres and over-sized bearings. A solid-state inverter gives precise speed control and a cast-steel gearbox with double-worm gears gives smooth operation and minimal backlash.
The CD-xxx-DB and CI-xxx-IB units are similar to the models above but available as motorised and idler types with a bogie to facilitate longitudinal positioning using floor-mounted rails. SD 5-100 and SI 5-100 roller beds have the added advantage of a self-alignment feature, in which the workpiece is supported by two pivoted roller pairs.
While remaining otherwise similar, the SD 5-100 DB and SI 5-100 IB self-aligning idler roller beds are equipped with a rail bogie. Where it is desirable to have control over positioning, the FIT 30, 60 and 100 idler roller beds are conventional units but with independently adjustable rollers to enable the two parts of the assembly to be aligned with each other. Taking this concept a step further, the FIR 35, 75 and 100 roller beds have four independently adjusted idler rollers, two for each part of the assembly.
In addition, a pair of cross rollers can be raised to support the completed assembly. Finally, the FUB 30 is a compete Fit-Up Bed that consists of one powered and one idler roller bed; four independently adjustable rollers to align the two sections of the fabrication; and a robust frame onto which the other components are mounted. Models outside of the standard range can be designed and built to specification.
