   ELEVATION & INNOVATION

    ELGI has been innovating and creating new
products on a regular basis, thereby keeping ahead
of the competition. The latest addition to their ever-
growing product line is the Wheels Free Scissor
Lift. The scissor-like structure makes the lift rigid,
sturdy and stable under stressful conditions. This
hydroelectric lift can lift up to an impressive 3000
kg, and is powered by a three phase 1440 RPM, 2
HP motor. The lift provides for effortless loading
and unloading using a drive-up ramp, and is rugged
and durable. The entire equipment is easily portable
and requires no expensive or time-consuming
installation procedures. It can be deployed for
various operations like pre-delivery inspection,
under chassis repair, etc. And enhancing this
complete solution is a pneumatic lock, provided
with the equipment for safety.
