Car area increases by 50 percent

The engineering and installation company in vertical transportation “Kledelmans” has developed a new arrangement for a lift car with its counterweight. According to the company, the newly arranged car area increases by 50 percent without changing shaft dimensions.

Nowadays skyscrapers are a key element of urban life. People in megacities spend a lot of their time in buildings while living and working in high-rise buildings. The main challenge in high-rise buildings is space.

It’s becoming more challenging for lifts to handle the traffic flow of passengers in high-rise buildings. Lifts need to occupy less space and transfer more people within less time. That is the main task for lifts, which is hard to implement given the daily increasing demands of urban life.

Time benefits with regard to heavy traffic flows

As an engineering and installation company in vertical transportation, “Kledelmans” has developed a new lift car arrangement with its counterweight. Thanks to this new arrangement, the car area increases by 50 percent without changing shaft dimensions.

This new design can be used for new lift installations as well as for modernization projects. It expands the available car area in group lifts, resulting in time benefits with regard to heavy traffic flows in residential and commercial buildings.

In a typical case, two lifts which are located in a common shaft are separated by a divider beam (metal beam) (picture at the top).

In this standard scenario, the shaft width is occupied by:
1. Area occupied by the counterweight
2. Metal divider beam, 150 mm width
3. Car guide rail bracket, 170 mm width (on one side)
4. The result is an effective occupied car area of (width and depth):
car width area: divider beam width & car rail bracket width on both sides = 150 + 2x170= 490 mm
car depth area: counterweight and its bracket at the back = 550 mm.

What if we can avoid these occupations in shaft width and depth, and let the car area become bigger and more useful without changing the shaft dimensions?

Let’s have a look at our multi beam product and what benefits it gives:
1) More useful shaft width and shaft depth area.
2) No area occupied in the width of the shaft by rail brackets. We remove the car rail brackets. Car rails are directly attached to the divider beam by rail clips.
3) No area occupied in the depth of the shaft by counterweights. We remove the counterweights from the depth of the shaft and locate them inside of the metal beam.
4) Lift installation time decreased by avoiding anchoring time for counterweight brackets.
5) Cost of material decreased by removing counterweight brackets, car rail brackets and anchor bolts.
6) Items “2” and “3” give us more useful car area without changing the shaft dimensions.

The main key benefits will be time and extra car area for heavy traffic flows in residential and commercial buildings without changing shaft dimensions.
