It is used extensively in factories and storage facilities for the movement of goods between floors. Two kinds of lifts are on offer – Drum-wound machine based or traction machine based. The capacities of this lift available at range from 250 Kgs to 10 Tons. Goods and workers can be transported to any number of floors. The size of the lifts can be from 3' x 2' to as large as 12' x 20'. Standard height of the cabin is 6' 71/2". The lift can open on the opposite side also (2 side open cabin).
Drum-wound type without counterweight – This lift is simpler in design and suited for low cost installations. The movement of the lift is based on the coiling and uncoiling of a wire rope on a rotating drum. A unique feature of our drum design is the provision of two ropes coiling separately on a right hand thread groove and a left hand thread groove. This leads to lesser rope stress and longer life. These lifts are quicker to install and require lesser space.
Traction type with counterweight – This lift is a better machine design wise and also offers greater safety to the user. This is achieved first through the use of 3 or more independent wire ropes stretched across the main traction sheave. Second, there being no positive coupling between the lift and the machine leads to greater safety as a slip is permitted whenever there is an obstruction to the lift travel. Unlike in the drum wound design there is no overload on the motor in case of lift overshooting at the top floor. Jerk free, smooth travel is possible by the usage of 2:1 roping. Though smoother, traction lifts travel at higher speeds than drum-wound lifts using the same power.
