A T-bar lift, also called T-bar, is a mechanized system for transporting skiers and snowboarders uphill, along the surface of the slope. It is generally employed for low-capacity slopes in large resorts and small local areas servicing skiers numbered in the dozens rather than in the hundreds or thousands. It consists of an aerial steel rope loop running over a series of wheels, powered by an engine at one end. Hanging from the rope are a series of vertical recoiling cables, each attached to a T-shaped bar measuring about a meter in both dimensions. The horizontal bar is placed behind the skier's or snowboarder's buttocks. This pulls the passenger uphill while they slide across the ground. A single T-bar transports one or two people. It can only be used for unloading trailers. It has lower cost than slipchain.
