Which parts of the elevator change is the transformation of it
The elevator transformation project includes: the main parts of the model, specifications change, such as: speed limiter, safety gear, buffer, door locks, rope combination, rail, traction machine, control cabinet, fire floor, glass doors and glass Wall, upstream overspeed protection device, safety circuit with electronic components, hydraulic pump station, speed limit shut-off valve, electric check valve, manual drop valve, mechanical anti-settling (anti-climb) device, step or pedal, cascade chain, , Wheel (main wheel, secondary wheel), metal structure, handrail, escalator or automatic walkway control screen. The main parameters and other content changes, such as: rated speed, rated load, drive mode, speed control mode, control mode, lifting height, running length (on the sidewalk), tilt angle, nominal width, explosion-proof level, explosion-proof media, The
For unillustrated elevators: there is a change in design-related changes. Simply put your installation site can not meet the installation requirements of the purchase of the elevator. For the aging of the old need to replace the elevator: the heavy burden of Cao nuclear ugly investigation of the new installation of the intestine can be considered a transformation. For the use of the elevator: simply replace the parts can not meet the requirements, you need to transform, such as: you want to load 1 ton of elevator carrying capacity of 1.5 tons. For example, you want the elevator speed from 1m / s to 2.5m / s. If only the inverter or host failure need to be replaced, it is not modified.
Parts adjustment parameters Adjust the following parts to change the model, specifications, so that the right column lists the elevator parameters and other content changes, should be identified as the transformation operations: speed limiter, safety gear, buffer, door locks, rope combination, Traction machine, control cabinet, fireproof door, glass door and glass car wall, upstream speed protection device, safety circuit with electronic components, hydraulic pump station, speed limit shut-off valve, electric check valve, manual drop valve, mechanical (The main wheel, the secondary wheel), the metal structure, the handrail belt, the escalator or the moving walkway, regardless of whether the parts listed in the left column are changed or not, The following parameters and other changes should be identified as the transformation work: rated speed, rated load, drive mode, speed control mode, control mode, lifting height, running length (on the sidewalk), tilt angle, nominal width, explosion proof, , The weight of the car see the mechanical and electrical special equipment installation and maintenance of the maintenance of the rules of the annex
