A mast lift (10) includes a base (12), a platform (16), and a lifting assembly connected between the base and the platform. The lifting assembly moves the platform between a lowered position and a raised position. A threaded driving rod (26) is connected between the base (12) and the lifting assembly, and a gas strut (28) acts between the base (12) and the lifting assembly and biases the lifting assembly and the platform (16) toward the raised position. |
