Portable and demountable lifting device

A lifting device, comprising:

• a mast defining a first channel and a second channel;
• a pulley supported by the mast;
• an actuator configured to be removably received within the second channel and securable at a various positions along the mast;
• a carriage slidably received within the first channel of the mast;
• a flexible connector having a first end and a second end, the first end coupled to the carriage and the second end coupled to the actuator, the flexible connector extending over the pulley;
• and
• the actuator operative to selectively reel the flexible connector in and out when the flexible connector is positioned over the pulley to cause the carriage to move up and down along the mast within a range between an upper position on the first section of the mast and a lower position on the second section of the mast.
