1. General safety rules
The assembly manual is a part of operation and maintenance documentation of TAS excavation stairs.
The stairs consist of elements fitting the specification added to the delivery.
Prior to the assembly works and operation, one should read this manual. The wrong assembly and usage
can lead to health and life threatening danger.
Due to high dimensions of particular components, one should act cautiously during transport, assembly
and use of the stairs.
Keep this manual as an information source for stairs users and a service team.
1. Assembly and use of stairs incompatible with the manual can result in a product malfunction and
may become a source of a danger.
2. The manufacturer takes no responsibility for any damage that resulted from the improper product
assembly or misuse.
3. It is forbidden to modify any of the stairs components.
4. The stairs are intended to be used in industrial conditions i.e. to be used by adults, who consider
health and safety rules, are trained and sober.
5. It is forbidden to stand under the stairs when they are being used.
6. It is forbidden to use the stairs by a number of people whose combined weight exceeds the weight
allowed on the stairs.
7. The stairs are designed to allow movement of people to lower levels of deep excavations and vice
versa. Standing on the steps, as well as putting objects which are not the components of the stairs is
against the rules of use.
8. The stairs should not be used to transport other objects than tools, devices etc.
9. Due to the fact that in most cases the stairs are assembled on unpaved ground, one should consider
the risk of ground sliding/ wetting which can affect stairs stability.
10. If there’s a risk of falling from a height, one should always use safety harness while assembling and
disassembling the stairs.

2. Components
The basic TAS excavation stairs components are flights of stairs with railings. Flights are
available in 3, 6, 9, 12,15, 18 step variants of 700 and 1000 mm width. The variants can be connected
using proper connectors and supports.
The system allows to establish a walkway over the obstacle with a platform and either 3- or
6- step flight. It is possible to use the stairs as gangways (e.g. over excavations) with 3, 6, 8, or 12 step
stairs, and with 15 and 18 step stairs with an additional truss application.
Exchanging the lower and upper foot of the stairs allows to assemble it on round, fi 48.3 mm
scaffolding systems.
