Anti-slip mats ensure that no movement is possible when transporting the load. This is because the anti-slip mat creates increased friction between the cargo and cargo floor. Make sure you have enough anti-slip material so that the object can rest completely on this. This way, it is still impossible for the object to move during the ride.
After the job is done, you can store the anti-slip mat or leave it on the loading floor. Just make sure not to get greasy liquid on it, the anti-slip mat will be smoother which will reduce friction.
