Brevini fluid power and gearbox expertise for quarrying

Fortunately Brevini Power Transmission and Brevini Fluid Power have many years of experience in their respective fields and are able to design complete powertrain solutions with no integration complications.

The environments encountered in mining and quarrying applications are extremely harsh. Heavy and abrasive materials cause impact damage, shock loading and corrosive dust while the machinery has to survive outside in extremely inhospitable environments. Due to the location of many mines and quarries, access to spare parts is often very limited, meaning that reliability is essential in any component specified for vital applications. For design engineers, finding companies whose products can be trusted to such difficult conditions can prove to be time consuming and frustrating.

Dave Brown, Sales Manager for Brevini UK Ltd, comments: "We’re aware that engineers are often frustrated by having to source components from different specialist suppliers and then trying to integrate them into a single powertrain design. Fortunately Brevini Power Transmission and Brevini Fluid Power operate extremely closely, meaning that components from the two brands integrate seamlessly with each other.”

Brevini Power Transmission is a leading global manufacturer of gearbox solutions for the mining and quarrying industries, with a focus on reliability and efficiency for high torque applications. Meanwhile Brevini Fluid Power incorporates seven of the leading brands within the hydraulic power industry: Hydr-App, SAM Hydraulik, Aron Brevini Hydraulics, VPS Brevini, BPE Electronics, OT Oiltechnology.. The two companies have been combining their technical competences and engineering abilities for many years; providing high-strength and high-efficiency solutions for OEM equipment builders and maintenance providers across Europe and the rest of the world.

A recent example of a combined solution from the two Brevini brands involved designing a complete package for material conveying and separating equipment. The requirement was for Brevini to provide a main drive to deliver a torque of 9,000Nm and output speed of 4.0rpm, as well as two chain drives and a spinner drive that were each required to deliver a torque of 3,000Nm and output speeds of 4.0rpm for the separating process. A hydraulic power pack would also be required to feed pressure to individual hydraulic motors at each of the four gearboxes.

Brevini was able to supply four of the unique PIV Posiplan bevel planetary helical gear units each, with a Brevini Fluid Power motor and an 11kW, 250L hydraulic power pack that included proportional control valves for PLC control. The overall lifetime of the package was calculated to exceed 50,000 hours.

The gearbox for the main drive was a 3 stage Posiplan BPH323 gearbox with an ISO6336 torque rating (T2ISO) of 15,100Nm and a reduction ratio of 58.82:1. The gearboxes for the chain and spinner drives all used 3 stage Posiplan BPH313 gearboxes with torque ratings (T2ISO) of 3,900Nm and reduction ratios of 45.68:1. Combined respectively with Brevini Fluid Power BR200 and BR080 orbit motors, the drives comfortably delivered the required torque and speed specified by the application.

Dave Brown continues: "OEM’s benefit from the unique situation of specifying components from two companies that are technical leaders in their respective fields and who communicate to ensure that these components work together efficiently and reliably. The sales engineers from both Brevini Power Transmission and Brevini Fluid Power are knowledgeable about the entire Brevini range, meaning that engineers can specify a complete package solution from a single source.”
