These manlifts are light in weight and are designed for use in areas where the ground load bearing strength is a point of concern, like in cast slabs inside a factory. These machines have special extendable outriggers that are hydraulically operated. These machines normally do not have any drive mechanism and have to be towed from one place to another. These machines are mostly battery powered and are very useful for indoor work areas such as airports, warehouses, malls, etc.
