A friction grip hoist (1) includes: at least one body (2); a pulley (3) mounted on the body, the pulley including a pin (4) and a wheel (5) having an outer peripheral groove (6) for receiving a cable; drive elements (7) for driving rotation of the wheel; and holder elements (15) for holding the cable inside the groove (6) of the wheel. The pin, referred to as a “dynamometer” pin, about which the wheel of the pulley is mounted to rotate is fitted with measurement elements (11) for measuring at least one magnitude representative of at least radial forces or loads exerted on the pin, and the hoist includes a monitor unit fitted with processor elements and with elements for issuing an alert signal and/or for controlling the elements (7) for driving rotation of the wheel of the pulley as a function of the at least one measured magnitude.
