A method of constructing a structure in which an item is to be installed at an elevated height on the structure. Hoists are hung from the structure. A platform is moved from ground level and positioned at a first elevated position between ground level and the hoists. The platform is attached to the hoists at the first elevated position. After the platform has been attached to the hoists, the item is moved onto the platform. The item is lifted on the platform to a second elevated position for installation at the elevated height on the structure and the item is installed at the elevated height.

A hoist system includes a motor with a drive shaft connected to a traction sheave, traction drum, or pinion. The hoist system further includes a compartment configured to at least partially enclose a direct current power supply such that the direct current power supply is electrically connected to the motor. The motor is configured to receive an input and convert the input to movement of the drive shaft as an output, and the motor is configured to be coupled to a load such that movement of the drive shaft moves the load.
