The EU en standard is an international standard, published as an official document in June 2005. EN1004 is the European Union's national standard for the design, manufacture, testing and use of movable scaffold or platform products. This standard replaces HD1004.
Early to rise, with the development of European construction, the development of movable scaffold has two big problems:
1 the mobile scaffold or mobile platform manufacturers in the process of prefabrication or building products, four legs and mobile casters design in a very unsafe state;
2 The escalator manufacturers consider the use of movable aluminum structural worktable with castors, the same unsafe factors
As a result, cen/tc53 in 1980 decided to establish a standard for mobile scaffolding and platforms, comparable to the European scaffold standard en12810-2 and en12811-3 levels. In constant refinement, the current EN1004:2004 is the latest version.
Movable aluminum alloy Scaffold
Movable aluminum alloy scaffold is a kind of product form of movable scaffold, which is built in strict accordance with EN1004 standard design.
The EN1004 standard is suitable for the design of movable scaffold, the manufacturing height is from 2.5m to A. 0m (indoor), Width 2.5m to 8.0m (outdoor).
-Guide The selection of the main dimensions and stabilization processes;
-Safety and performance requirements;
-some information about the full workbench.
Its test projects include:
-Overall structure size (including platform board size, net height, guardrail size, stair size, etc.)
-Overall structure most unfavorable load combination test (sample overall height is not more than 3m)
-Platform uniform load (level 2 or Level 3)
-Force deflection of platform components
-Force deflection of guardrail
-Vertical component combination tilt angle-integral structural stiffness test
