PRODUCTS LIFT TRUCKS NEAR SILENT HYDRAULICS OPERATION FOR QUIETEST FORKLIFT
Hiab Moffett has been at the forefront of the materials handling industry for more than 45 years. After observing increasing demand among its customer base of manufacturers, warehouse operators and supermarket chains for quieter materials handling equipment, the company set to work creating the world’s quietest truck mounted forklift. In order to ensure the machine’s
operation could be as silent as possible a key area of focus was the gear pump. With Bosch Rexroth already supplying hydrostatic drives and gear pumps across the vast majority of Hiab Moffett’s Truck Mounted Forklifts engineering director Kevin Turnbull approached Craig Grant, mobile applications manager at Bosch Rexroth to see if the company could provide a solution.
“There has been a trend in recent years
where deliveries are made not just to typical building sites or industrial estates but to residential areas,” says Turnbull. “With this in mind operators need to be aware of lower noise emission thresholds, particularly at night or in the early morning when most supermarket deliveries take place. Because of this we were seeing increasing demand for quieter fork lift trucks and took it upon ourselves to develop a near silent version for those customers where keeping noise pollution to a minimum is a top priority.”
brought a product to market that as well as meeting its demands for an electrically powered pump operated with near silent hydraulic functions.” Developed specifically for mobile
applications and forklift trucks in particular, the Rexroth Silence Plus Gear Pump was highly commended in the Noise Abatement Society Awards 2011 and provides a more robust bespoke design for use on moving vehicles. To demonstrate noise reduction
potential of the new pump Craig provided sound files of a traditional gear pump running at 1500 rpm across different pressures alongside the company’s silence pump and the latest silence plus pump. “Having used and specified hydraulic
“Having worked with Hiab Moffett for a
number of years we knew that noise pollution was becoming an increasing concern for the company’s customer base,” comments Grant. “While there was a product on the market that professed to reduce noise emissions it hadn’t been specifically developed for mobile applications. Fortunately when Hiab Moffett approached us we had just

pumps for a number of years I had become used to the fact that they have a relatively high operating noise,” concludes Turnbull. “While we used a supplier in the past who supplied a helical pump, its functionality wasn’t optimised for use on forklifts. Once Craig demonstrated the noise reduction capabilities of Bosch Rexroth’s latest pump along with its increased functionality and durability it was a simple decision for us to work with the company.”
