ALC Truss S-60-M2 MINI TOWER mk2 INSTRUCTION MANUAL V1.0 7/21
GENERAL CONDITIONS OF SETUP
Given the above safety instructions, make sure the following both general as
environmental conditions are guaranteed:
•As clearly shown on the product label and noted further in the set-up manual, the
allowable vertical load is strictly limited to 650kg.
•Specific requirements with regard to the subsoil or soil structure and pressure
capacity must be considered: the direct local soil pressure must, for example , be
divided by means of plastic, hardwood or metal distribution plates under the basic
construction, when used on sandy soil for example.
•For indoor use, wind forces can be neglected and result in a minimum reaction
force in the support points of 300kg (screw jack area of 150mm x 150mm)
•For outdoor use, the maximum reaction force in the supports can be 1.100kg.
•Be aware that when setting up the tower system, you need at least a rectangular
space of about 4m wide and 9.0m long. During set-up, make sure this space does
not block any important passages or so. Do not allow people to enter this space
under any circumstances. Once upright, the tower basis takes about 6.5m² of
space. It is advisable to restrict an additional area of 10m² around the tower, for
example by fences.
•While preparing and setting up the tower system, make sure only people involved
with its set-up are allowed in the neighbourhood of the MINI TOWER mk2.
•When using outdoor, wind speeds of up to 75 km/h (8 Beaufort –20m/s) are
allowed, taking into account the following limits for load dimensions.
Maximum horizontal projection surfaces: Front : 4,5m²
Side : 2,0m²
•As soon as the wind speed exceeds this value, the load must be lowered.
•The load can be placed on the base, platform, sub speakers,… with the hoist being
minimally loaded to keep the load on the system stable. This way, extra ballast is
created on the basis of the structure to guarantee a safe and stable situation in
case the wind speeds exceed the maximum operating values.
•When setting up the MINI TOWER mk2, when the mast is raised vertically, wind
speeds must not exceed 5 Beaufort (40km/h –11m/s)
