A mobile transport device and a method for introducing an installation frame into a shaft, in particular an elevator shaft, are used for transporting an installation frame and for introducing the installation frame into the shaft. The installation frame has a base frame and a bearing frame on which the installation frame is supported from above. The transport device additionally has a fixing device arranged on the base frame for fixing the base frame to a shaft opening of a shaft wall of the shaft and for preventing the transport device from tilting. The bearing frame is supported by the base frame and is movable in the horizontal direction relative to the base frame such that, when the base frame is arranged outside of the shaft, the bearing frame, and thus also the installation frame, can be moved into the shaft from outside the shaft through the shaft opening.

Devices, systems, and methods are provided for helping hand trucks lift heavy objects. A device for attaching to hand trucks and lifting objects may include a pallet portion for lifting weight, the pallet portion having a bottom portion facing the ground and a top portion, wherein weight is arranged on the top portion; an angle maintaining portion attached to the bottom portion, wherein when the angle maintaining portion is touching the ground, the pallet portion is positioned at an angle greater than zero relative to the ground; and one or more slots attached to the bottom portion, wherein the one or more slots are configured to attach to a hand truck nose blade by sliding the hand truck nose blade into the one or more slots.
