Scaffolding is a temporary structure on the outside of a building made of wooden planks and metal poles, used by workmen while building, installing, repairing or cleaning the building.

 Scaffolding is required during lift installation and its quality has influence on the safety of the personnel working on the lift installation and the overall progress of the lift installation.

Wood and profiled steel pipes of rectangular sections are materials usually used to make template holders. Template holders are the heart of an elevator and its a guide for the full installation process. The framework is made according to the measurements in installation drawings. Profiled steel is usually used for high rise lifts while wood is the least used.

Template holders  setup

Template holders are fixed in the hoistway 500mm below the floor of the machine room, in a scenario where there is no machine room or there is a small machine room the template holders are fixed in the hoistway 250mm below the top plate of the hoistway.
