Internal Tension System The component range of the ITAS internal tension system has been extended with some additional variations. These permit completely new construction possibilities. The fixation of the tube occurs through a clamping rocker/thrust pad by turning the clamping screw.

Quick Change System The ITAS Quick Change System enables protected working or machine areas to be accessed with little manipulation and without requiring a lot of tools. The system avoids railing having to be completely dismantled e.g. for repair work.

Dismantling of Quick Change System

Building Regulations for Railings According to UVV, VBG1 and Conforming to DIN EN ISO 14122-3
"Construction Type" Tested

Example	Dimensions [mm] max.
Example	A	B	L
1	500	1000	1500*
2	500	1000	1500*
	*The support spacing "L" must ensure that 340 Nm for base fype FI40 is not exceeded.

Example 1, wall and floor fixing

Example 2, self-supporting
with floor fixing

Load Data

• Load data according to DIN 1055
• Maximum admitted load of steps (for a length of 1.2 m) 1500 N
• Maximum admitted load of stairs cross beams (for a 45º angle
and length of 4 m without support) 3500 N
• Maximum admitted load of railing (distance between pillars
0.7 m) 500N

• The maximum admitted load of the platform depends on the base
   construction. It cannot exceed the maximum admitted load of the base
   clamps used.
• Technical safety requirements in accordance with DIN EN ISO
   141221-4

Example for Horizontal Railing

Example for Stair Railing - Catwalk Connector

• The railing must have at least one knee rail
• Do not exceed a free space between the
handrail and knee and foot rail of 500 mm
• Fit a foot rail with a minimum height of 100
mm maximum 10 mm above the step level

A staircase must have a least one handrail. With a flight width equal to or exceeding 1200 mm two handrails must be provided in the same manner as with all ladder stairs.
