We also sell lightweight aluminium lifting gantries complete with castors (wheels). Some designs are suitable for moving the gantry wit-out the load applied and others are potentially movable under load. There are many factors to take onto account before the employer / user decides to use a gantry under load (with the load applied to the lifting beam) To help decide if a gantry / application is going to be suitable please see the “Moving Under Load” tab on each product.
