摘要： A multi-stage mast module is cooperable with a mast lift. The mast lift includes a base supporting the multi-stage mast module and a platform coupled with the multi-stage mast module. The multi-stage mast module includes a mast unit including a plurality of telescoping mast sections, and a multi-stage drive connected between the telescoping mast sections of the mast unit. Gas springs are connected between the telescoping mast sections of the mast unit. The gas springs act between the adjacent ones of the telescoping mast sections

摘要： A mast lift includes a base, a platform, 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 is connected between the base and the lifting assembly, and a gas strut acts between the base and the lifting assembly and biases the lifting assembly and the platform toward the raised position.
