This Assembly guide is designed to provide you with step by step instructions to ensure your system is
erected easily and safely using the 3T (Through the Trap) Safety Standard. Before assembly please read
the safety notes carefully.
Snappy 300 is a mobile access tower system complying with EN 1004 and WAHR, anti slip frame access, designed for Class 3 loading.
Safe Working Loads and Working Heights
(WAH R)
The total loading on the tower structure should not
exceed 360kg. Maximum platform height for indoor
and outdoor use is 4m.
ASSEM BLY PROCESS
1. Preparation
Install the castors into the uprights if not already done.
Sort the braces into horizontal and diagonal braces - the diagonals are slightly longer.
Unlock the brace locks.
2. Base
Follow the erection procedures as shown (Section 4). It is important to follow the
bracing pattern precisely. If extension frames are being used, ensure they are “locked”
using the interlock clips.
3. Locking down the platform
A windlock clip is installed on the platform at the hook. This is locked as shown here.

3T Safety Standard - TH ROUGH TH E TRAP
This is an approved method of tower construction
which, if carried out by a competent person,
complies with all current safety legislation.
Construction - basic principles
• Always install the trapdoor platform over the
ladder (if one is fitted).
• Ensure the trapdoor hinges to the
OUTSIDE
of
the tower (not the centre).
• Once the platform has been installed, climb, using
the approved method and
SIT IN TH E
TRAPDOOR OPENING.
• While seated, attach horizontal braces to the
frames to form guardrails on
BOTH SIDES OF
TH E PLATFORM.
• See assembly instructions for specific placement
of guardrails.
• 2 braces are normally required each side -
although bracing frames can be used on the
outside if desired or specified in the instructions.
• Only when the platform is fully guarded is it safe
to stand up.
Dismantling
• Unlock the brace ends furthest away from the
trapdoor.
•
DO NOT REMOVE BRACES U NTIL SITTING IN
TH E TRAPDOOR.
REMEMBER - NEVER STAND ON AN
U NGUARDED PLATFORM
