|PREPARATION OF CONSTRUCTION SITE||TYPE OF CHECK|
|Dimensions||The check applies to:
|Access routes and free spaces||
It is necessary to identify “manoeuvring spaces” for the installation of escalators in a way that avoids the event of obstacles during the assembly operation.
|Measures necessary for unloading||
During the unloading phase, a mobile crane or camion crane of adequate size is always necessary.
The same method will be used for the junction of the trellis and its positioning in the compartment
|Installation via pulleys||
When it is not possible to use the crane for the positioning of the trellis, for example in existing buildings, it will be necessary to use attachments on pulleys that can withstand a load of 80kN.
The installation will be transported into the interior via wheels, access routes should be smooth and free of obstacles, and the slab must support a concentrated load of 40kN.
In the case of installation via pulleys, the intermediate support (where present) must be constructed after the positioning of the structure.
|Upper, lower and intermediate support||
The bearing plane of the supports must be levelled and able to support the weights indicated on the approved technical drawing.
Depending on the type of installation (escalator or travelator), a “tooth” is required for the support slab of different dimensions.
Travelators with a cantilever of more than 10m, and escalators with a cantilever of more than 15m, are also equipped with intermediate support
|Electrical supply||The supply is always included in the upper section of the motor.
Every installation entails a separate supply line: three phases + ground via cable of suitable section (from 6 to 10mmq)
|Watertight trench / Draught pump||Interior installation: the trench must be watertight and free of infiltrations.
Exterior installation: after positioning of the installation, it will no longer be possible to access the trench. The trench must be watertight and free of infiltrations An adequate outflow of rainwater must immediately be provided for by a drainage canal or draught pump. It is advisable to provide lateral access to the trench for cleaning and maintenance operations of the drains.
