Manual-MPT Tower
NOTE
The spans of trusses to be checked for loading data are about 0,5 m larger than the planned span
because of the extension from 2 x 0,5 width of the sleeve blocks.
Before the loaded system is raised check the vertical position of the towers and proper surface contact
of the screw jack dishes.
Run the system up to trim height, and secure it in this position by means of a secondary independent
support such as a clutch chain or wire rope.
Check if all the towers are in an exact vertical position, using a level with a plumb-position-eye.
Correct any angles in tightening or releasing the screw jacks of the base outriggers.
Connect all the towers to earth, if there is any danger expecting electrical installations that might short-
circuit. Make sure a qualied person, knowing the local (soil-) conditions and legal regulations makes
proper earth connections.
WARNING
Electrical hoists that malfunction within the system, caused by short circuit or moist weather
conditions, will prevent the ground support from being brought down when necessary.
Always make sure that the oor or subsoil is sufciently capable of carrying the load of the system
+ towers as it is transferred through the screw jack dishes. Use plywood panels or similar material to
increase bearing capacity if needed. When in doubt check with a competent person.
The complete set of base section, lower mast section,
sleeve block, hinge set and top section can be assembled
as one compact set to facilitate loading, building and
warehousing.
Size: 60 x 60 x 155 cm, weight +/- 115 kg.
