The Goods Lift design engineers were able to specify a MezzLift from their goods lift brochure which helped to keep project costs to a minimum. The MezzPro mezzanine lift was specified which had a maximum working load of 500kg. This was more than enough capacity for the laundry trolleys and would ensure that the lift was suited for heavy usage.
The MezzPro is enclosed in a self-supporting mesh shaft and no lift pit was required for the installation, this was also a big advantage of the MezzPro as this meant that no structural changes to the building were required…again helping to keep costs down. The platform was sized at 1000mm x 1000mm to suit the laundry trolleys and guarding was included at 900mm high on the non-loading edges of the goods lift.
At the entrance to the MezzLift at both levels there were 2000mm high gates, fitted with electrical interlocks to prevent the gates being opened unless the platform was docked at the appropriate level and prevent the lift being operated unless all gates were closed. At the lower level a 500mm long fixed ramp was included to assist loading the laundry trolleys on to the 50mm deep platform. A 2.2kw, 415 volt, three-phase and neutral supply was required terminated in an isolator at the lower level and control was via a hold to run, push button control station adjacent to the gates at both levels
