Used extensively in factories and storage
facilities for the movement of goods between floors. Two kinds of lifts are
on offer - Drumwound machine based or traction machine based. The capacities
available 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' 7½". The lift can open on the opposite side also (
2 side open cabin).
Drumwound 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 designwise
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 drumwound lifts
using the same power.
