Explanation For The Model Codes:

SIGMA MRL E1000 model code is composed of 11 characters.

Numerical digit1: indicates the type of the elevator (P means passenger lift)

Numerical digit 2-5: means the duty load.

For example, 0630 means that the duty load is 630kg.

1000 means the duty load is 1000kg.

Numerical digit 6: executive code and standards.

G means GB series.

Numerical digit 7& 8: brief mark of rated speed.

06-0.63m/s; 10-1.0m/s; 15-1.5m/s; 17-1.75m/s;

Numerical digit 9: car size. W – wide car; D– deep car.

Numerical digit 10-11: door type.

standard：CO---center opening; 2S---side opeining

8. Pit Material

The pit material consists of pit lighting, emergency stop switch, hoistway lighting switch. All

the wirings adopt AMP quick-assembly connectors.

9. Traction Rope & Governor Rope

Traction rope use 10mm steel wire rope.(When DL<=450kg, the rope is 8mm)

governor rope use 6.3mm steel wire rope.

10. Hoistway lighting

Lamps are provided along the hoistway with a spacing of 7m.

Two lamps have to be placed at 0.5m above top of hoistway and 0.5m above pit respectively


Revision: 06


Binder


The lighting switch is set in the controller and pit respectively.

Remark : If lighting power isn’t 220VAC, factory supply hoistway lamp wire, local should

provide hoistway lamps & lamps holders.

11. Compensation Chain

The immersion plastics chain is used for SIGMA MRL E1000.

Car

1. Car Frame

SIGMA MRL E1000 car frame is shaped with bending sheet and bolts assembled. It includes

platform support frame. The platform support frame can be used as installation platform

when installation.

Crosshead Hitch

Safety Block is assembled at foot of frame. It is manufactured according to SIGMA

Specification.

Guide shoe, select sliding guide.

The balance weight to be used if required.

2. Platform

The platform of SIGMA MRL E1000 is shown in the below figure.

The enclosure is assembled at the side of platform with pop nut and bolts. The car threshold

is made of aluminum alloy with dust holes left. The thickness of floor decoration is 3mm, and

the process of standard floor decoration is sticking wood board on floor sheet and then

sticking floor hide (FL01M, FL02M, FL03M, FL04M, FL05M, FL06M, FL07M, FL08M). There

are no floor tile and wooden plate in the optional decoration, The thickness of floor

decoration is 30mm.

SIGMA MRL E1000 uses mechanical three points weighting device with micro-action switch.

3. Top of car Protection
