Wheeled trolleys to carry maxi drums can be found on the market. This solution entails the use of one trolley for each drum, which means having to purchase a minimum of four to a maximum of eight trolleys for each pool.

Instead, Patentverwag’s solution envisages the use of a single LEVER/X trolley for all the drums: a trolley that can easily raise one drum at a time using a lever arm and can easily manage lane marker handling and, most important of all, costs three/six times less than the traditional solution.
