How do I calculate the shaft size for an elevator in Pakistan?

Select your rated load and door type in the Liftech configurator — hoistway width and depth are derived from ISO 4190-1 cabin envelopes plus guide-rail, counterweight and door-sill clearances, then verified on site by our engineers.

What pit depth and overhead clearance does a lift need?

Pit depth and overhead clearance scale with rated speed under EN 81-20/50 — typically 1400 mm pit and 4200 mm overhead at 1.0 m/s, rising to about 2400 mm and 5600 mm at 2.5 m/s.

Elevator Configurator — engineer your lift in four steps

Select application and capacity, enter travel height, and the configurator derives hoistway width/depth, pit depth and overhead clearance to EN 81-20/50 and ISO 4190-1 planning practice — then customise the cabin and request an official quotation.

How the Liftech elevator configurator calculates your shaft

Cabin envelopes follow ISO 4190-1 load classes; hoistway width adds guide-rail, counterweight and door-sill clearance, while depth allows for the car sling and landing-door pocket. Pit depth and overhead clearance are derived from rated speed under EN 81-20 §5.2.5 buffer-stroke and safety-space rules. All values are preliminary planning figures — Liftech engineers confirm them during a free site survey in Karachi, Lahore or Islamabad before drawings are issued.
