With a pump jack pulley, contractors and employees would be able to load material onto the pulley and lift the material safely without putting a strain on their back. The pump jack pulley is very simple when it comes to design, but a high quality and reliable product. It can be manufactured for a fraction of the cost of the heavy machinery available, which would make it affordable and available to a wider range of construction laborers. This would allow for the product to be used throughout the full project, saving time and increasing efficiency.
