How much strength is required to move 150kg? None. Thanks to the TENTE e-drive. In cooperation with our customer Mercura, we put this solution into practice, at the Starling Hotel in Geneva.


Mercura Industries Suisse S.A. produces lightweight aluminium service trolleys and is present in more than 45 countries. These products are used in hotels, airports and healthcare facilities, for example. The company was commissioned by the Starling Hotel & Conference Centre Geneva to provide new trolleys for room service and for restocking the minibars. Starling Geneva is the largest 4-­star hotel in Switzerland. It has 496 rooms, 43 conference rooms and 270 employees.


Mercura Switzerland’s service trolleys are used in aisles which have very thick carpets. The unfavourable running properties on this floor covering and a trolley weight of up to 150 kilograms combine to produce an extremely high rolling resistance. This makes it almost impossible to move the service trolleys without assistance. In order to minimise the effort required of hotel employees, Mercura were looking for a solution that would help overcome the resistance. For the hotel, it was essential to create optimum working conditions for its employees, minimise the burden and protect their health.


We equipped each of the 15 service trolleys with an e-drive. A control unit on the handle allows flexible control of the drive aid. If the cleaning personnel activate the e-drive, an electric drive wheel lowers and helps personnel to move the trolley. In combination with four swivel castors, specially selected to deal with this situation, the solution noticeably simplifies forward movement and makes it possible to drive the service and bar trolleys effortlessly, even on the high pile carpet.

The innovative system has been successfully perfected during the course of TENTE’s project partnership with Mercura, whilst also working closely with the employees of the Starling Hotel. Together, we have optimised the motor parameters to correspond to the weight of the individual trolleys and adapted the performance of the rechargeable batteries. Now the e-drive is able to lighten the load for service personnel all day long, as well as provide continuous assistance to the staff.


With the help of this smart solution, service personnel can move the heavy service and bar trolleys effortlessly along the hotel’s long corridors. The e-drive noticeably lightens the employees’ load and enables them to concentrate fully on their actual tasks.
