The Lift mast is provided with top and bottom limit cams. These cams will actuate limit switches fitted to the Lift itself, making it stop automatically. A three-phase switch breaks the current if the normal control limit switches fail to function

The cage cannot climb off the mast, thanks to the safety hooks around the corner tubes of the mast.

There are also strong buffer springs fitted at the bottom for extra safety.

It is vital to have a safe way of stopping the Lift cage, if the speed becomes high then rated speed. The Lift has a safety device that brings the Lift to a smooth stop.

The pinion of the safety device is driven by the rack. At normal speeds, the centrifugal weight is retracted, allowing the pinion to rotate freely.

At excessive speeds, the centrifugal weight is thrown outwards and connects the pinion to the brake cone.

Which is screwed in against the brake drum. The Lift is brought to a smooth halt, and simultaneously the power to the drive unit is cut off. It is simple to reset the safety device by using a tool provided in the cage.

Modular system is built up around basic elements comprising of comprehensive range of masts, Lifts cages and drive units. This system enables Lift to be tailored to suit almost any projects.

The Lifts are available in different cage dimensions. Due to the shape of the mast and cage, wind has minimal effect and least possible force is transferred to the wall. The cage can be tted with different types of gates, interlocks and control systems.

The machinery consisting of brake motor and worm gear is placed on top of the cage as well as inside the cage depending upon the requirement. The pinion is attached to the secondary shaft of the worm gear. The safety device is located below the drive system. A centrifugal brake allows for a controlled descent in the event of power failure.

The masts are available in different cross-section for a wide variety of applications and various load parameters. Some are square basically for heavy load capacity; others are rectangular in cross-section for medium and light capacity duties. There are at sections mainly for permanent installations. There are interlinking sections for coupling square masts to rectangular masts. The sections are supplied complete with a rack.
