Claim 0:
1. A lift device, comprising:
a lift assembly configured to be driven to increase or decrease in length along an upwards direction by extension and retraction of one or more actuators, the upwards direction being substantially perpendicular with a ground surface upon which the lift device is positioned;
a platform coupled at an upper end of the lift assembly;
a controller configured to:
receive a value of a pitch angle and a roll angle of the lift device from an orientation sensor, the value of the pitch angle and the roll angle indicating a slope of the ground surface in at least one direction;

receive a value of load on the platform from a load sensor;
determine a maximum allowable elevation of the platform based on the value of load on the platform and at least one of the value of the roll angle and the value of the pitch angle of the lift device; and
limit operation of the lift assembly based on the maximum allowable elevation of the platform.
