For the task of lifting equipment to the interior of a building from the road, where there is a sinking at the first floor location, which makes it impossible for a straight arm crane to lift, the SUNHUNK folding arm has a negative angle lifting capability of 15 degrees. This allows for easy lifting of the equipment into the interior of the building.
