Code: TT3500-S-Push The TT3500-S-Push is an electric tug that generates traction by using its own weight. Unlike the TT3500-S, which pulls heavy loads, this version pushes heavy loads on wheels. This electric tug is typically used in situations where carts already have a hook or folding hook, but the TT3500-S-Push can also be upgraded with a lifting module. This makes the tug suitable even for carts without a hook. This machine is used in data centers as a server rack tug for crating and uncrating server racks for transport. Thanks to the electric hook that firmly clamps onto the base of the server rack, it has a secure grip and can safely push the rack on its own wheels into the crates and remove it from the crates again.
