Safety is a major consideration in Elevator Factory design. The floor opening may be protected against fire by the addition of automatic sprinklers or fireproof shutters. The escalator may also be situated in an enclosed fire-protected hall. To prevent overheating of the motor and gears, proper ventilation should be provided.
If the escalator is the primary means of transportation between floors, a traditional staircase can be located near it. An elevator near an escalator is also ideal for accommodating wheelchairs and people with disabilities.
Two types of companies supply escalators. Primary Elevator Manufacturer build the equipment, while secondary suppliers design and install the equipment. In most cases, the secondary suppliers receive the equipment from the manufacturer and make the necessary changes.
1 The first stage of escalator construction is to establish the design, as described above. The manufacturer uses this design information to construct the customized equipment. The tracks, step chains, stair assembly, and motorized gears and pulleys are all bolted into place on the truss. The handrails are carefully coiled (wound into a loop) and packed. All the equipment is then shipped to the supplier.
2 Before installation, the top and bottom landing areas are prepared for connection to the escalator. Concrete fittings are poured, and the steel framework that will hold the truss in place is attached.
3 After the escalator arrives at the site, it is jockeyed into position between the top and bottom landing holes. Several methods are used to lift the truss into place. One method uses a scissors-lift apparatus mounted on a wheeled support platform. The scissors lift is outfitted with a locator assembly to help in vertical and angular alignment of the escalator. The upper end of the truss is first aligned with the support wall at the upper landing and then placed on this support wall. The lower end of the truss is put into a pit on the floor of the lower landing. If the handrails come separately, they are connected to the appropriate chains after the escalator is installed.
4 The escalator is connected to the power source, and the tracks and chains are checked for proper alignment.
5 Final checks are then performed to ensure that motorized parts are functioning properly, the belts and chains are moving smoothly and at the correct speed, and the emergency braking system is activated. The step treads must be far enough apart so that they do not rub against one another. However, they should be positioned in such a way that no large gaps are present. Such gaps could be a source of injury.Fujihd elevator company is a world class China elevator manufacturers and elevator factory, Fujihd has rich product varieties.
