Ladder without scaffolding installation method

Never scaffolding installation process main is platform drag operation by the driving means, the hoistway rail brackets, rails, landing door apparatus, a car and the counterweight tray and other equipment installation. Their drive can be divided into: the traction drive, climb elevator drive and hoist drive. Lifting the elevator components to the specified location in the engine room, the upper template, set the lower part of the model in the bottomless pit. The first rail is installed in the pit. Install the operating platform in the pit (elevator traction machine driven engineering methods to install the car frame). Installation of various security measures, such as protective layer door. Install the traction wire rope to complete the control device wiring work, the drive is running elevator traction machine driven engineering methods should first install the the rail lift heavy driving device drag work platforms along the installation is complete, the installer to use the operating platform for installation of elevator components and electrical wiring job. Work platforms operated by the installer, the installation must have safety gear, safety belts, protective layer door safety device. No scaffolding installation method in the operating platform construction, from an objective to avoid the interchange operations, to eliminate potential accidents, improve the safety factor at the same time the elevator installation and construction safety measures more stringent requirements, specifically the following measures: landing door opening security. To prevent splashing and falling debris from wells outside layer door opening security and room opening security must be strictly set. Protective roof. To prevent splashing and falling from the work platform above the debris, must be installed above the work platform protective roof. Safety bars. Were set around the work platform safety rails with a height of 1.1 meters, and install baseboards. Professional emergency stop switch. To prevent unauthorized operation of the other workers, professional emergency stop switch is set in the operating platform. Upper limit switch. Since the guide rail at the top of the hoistway is not yet installed, when the rise of the operating platform, beyond the rail to prevent the work platform on the side of the guide shoe to install upper limit on the operating platform switch. The lower limit switch. When the decline in operating platform, in order to prevent the operating platform collision with pit parts, install the lower limit in the operating platform switch. Seat belts. Into the operating platform construction installation personnel must strictly the use of seat belts. Safety warning signs. Safety warning signs posted in the striking position of the operating platform. Construction Notes and emergency measures. Daily inspection items for scaffolding construction method, in accordance with the requirements of the inspection by the person in charge of the installation team and fill out, and when the emergency measures in the event of special circumstances. Worker safety education. Scaffolding construction method must be comprehensive by the elevator installation skills, a strong sense of security, received construction scaffolding workers specially trained installer. Scaffolding installation method need to be transported to the landing door device and rail brackets and other components by the installer required to install layers, installation labor intensity. 30-story elevator installation, for example, the installation of the components of the landing door device layer door, door pockets, the floor door sill and floor door sill handling layers 4 group takes about two days; while the use of No scaffolding installation method as a means of transport by the operating platform of the parts shipped to the layers, more significant advantage for high-rise building elevator installation. Scaffolding installation method to install an elevator four installers, without the scaffolding installation method only requires 2 to 3 installer to complete the installation work (1) to meet the requirements of the power supply must be sent to the elevator machine room before the installation of the elevator. As no scaffolding installation method requires the use of drive unit drag the operating platform for installation of elevator components, power supply can not install leakage protection device (2) The power supply must meet the requirements of elevator operation. Site construction power requirements with leakage protection device. But now a lot of the manufacturers elevator with frequency converters, the elevator operation causes leakage protection often affect the operation of the elevator, the site needs further coordination, power supply leakage protection device to meet the requirements of elevator operation. (3) the elevator shaft without workover wall of the hoistway can not have debris. Erection of scaffolding wells, workover operations can not be carried out. The elevator hoistway wall of the civil reinforced reserved, templates, and other debris will hit the elevator car frame and the heavy impact of the elevator installation. No scaffolding installation method is particularly important wells and check before installation. (4) elevator shaft size is too large for using this construction method. When the distance between the edge of the wall of the elevator shaft and the car is more than 700mm, standing installed on the operating platform you want to install the rail brackets and other components, platform far from the shaft wall construction is more difficult, such as the forced installation can be a security risk, so The elevator hoistway oversized this method is not suitable for installation. (5) is not suitable for the installation of elevators without machine room. The machine room less elevator traction machine is installed in the elevator shaft, if the installation of the construction method needs further study. (6) elevator components shipped complete. (7) the elevator shaft opening layers required to set up protection. In summary, no scaffolding installation method is a state-of-the-art elevator installation practices, vigorously promoted across the country, the key is to regulate the construction and installation team on site civilized administration. Vertical elevator installation with no scaffolding construction method, elevator installation unit has always been the goal, is the the elevator installation direction of development in the future, although the current construction method is still some ways not restricted to the rapid adoption, but after the elevator installation industry research and efforts of stakeholders, no scaffolding installation method will be more complete, using a wider range, more suitable for installation on-site operation.Elevator Parts
