Drawings and technical specifications

Shaft, pit and machine-room drawings with reference dimension tables for each lift line. Architects and contractors can use them to reserve the shaft right from the design stage.

Reading the drawings

Labels on the drawings

The drawings keep the equipment manufacturer's original English labels. The table explains the most common ones. Dimensions are in millimetres, forces in newtons.

Figures are for design reference only. Before construction, ASAHI engineers survey the site and issue installation drawings specific to the project.

Options

Door types and glass car shapes

Two-panel centre opening

Two panels part to both sides for quick boarding. Common on passenger lifts.

Two-panel side opening

Both panels stack to one side, making the most of a narrow shaft. Often used on home lifts.

Four-panel centre opening

A wide opening for stretchers, trolleys and bulky goods.

Single-side opening

Large panels slide to one side; used on goods and hospital lifts.

Semi-circular
Square
Cut corner

The bold line on each glass car shape marks the safety glass.

Rope traction, machine at the top of the shaft

Home lift

Reference drawing for a 4 – 5 person home lift. ASAHI home lifts also come in shallow-pit and screw-drive versions; final dimensions are set after the site survey.

Machine room no larger than the shaft

Passenger lift with small machine room

The machine room is simply an extension of the shaft and takes no extra floor area. Gearless permanent-magnet machine and a compact controller.

Standard and compact versions

Machine-room-less passenger lifts

The machine sits inside the shaft, so no machine room is needed and about 10% of building area is saved. The compact version suits narrow shafts in townhouses and small offices.
