Debris elevator manufacturing and installation of safety norms

1 Scope

1.1 This new manufacturing and installation permanently installed power driven or forced Traction lifts and hydraulic lifts of

Safety guidelines should be followed. Lifts serving the predetermined landing stationary lifting equipment. It has a size of a car, and the car

Structure type does not allow personnel to enter. A car suspended by means of a rope or chain or plunger supported by the electric or hydraulic drive and the vertical line

Running on a rigid rail inclination is not greater than 15 °.

This standard applies to the rated load of not more than 300kg, and does not allow delivery personnel lifts.

1.2 In addition to the provisions of this standard should be considered (such as a potentially explosive atmosphere, extreme weather, earthquakes, dangerous goods cargo in special circumstances

Transportation, etc.) supplementary requirements.

1.3 This standard does not apply to.

a) 1.1 lifts than the driving mode;

b) prior to installation of the present embodiment and standard lifts major conversion has been completed (see Appendix E);

c) lifting devices, such as bucket elevators, lifts mining, stage elevators, hoists with automatic equipment, construction hoist, marine

Elevator, mining or offshore drilling platforms, construction and maintenance of the equipment used;

d) the inclination of the guide rail and the vertical line is greater than 15 ° of lifts;

e) transportation, installation, maintenance, and safety during the lift debris removal;

f) the wall of the hoistway, the car and landing doors (including windows) using glass.

However, the above apparatus may comply with this standard.

This standard does not involve noise and vibration problems, because these problems has nothing to do with the safe use of lifts.

This standard does not relate to the spread of fire.

1.4 due to not allow personnel to enter the car, the car's size should not exceed.

a) a bottom area of 1.0m2 car;

b) a depth of 1.0m car;

c) the car height 1.20m.

If the car is composed of several fixed intervals, and each interval of the above requirements are met, allowing the overall height of the car is greater than 1.20m.

In particular, the delivery of goods as lifting equipment, if their car size than any one of the above parameters, do not fall debris elevator

category.

1.5 standard is applicable to rated speed is not greater than 1.0m/s to lift debris.

Note. speed exceeds the lifts, additional requirements should be used in order to obtain an appropriate equivalent security.
