Safety functions when lifting and handling
The Winlet 350TH is equipped with an operating panel from which all vacuum and hydraulic functions are
controlled. The integrated safety functions are:
•
2-button safety operation of the machine's vacuum system. Both buttons must be activated at once
either to pick up a load or to put down a load.
•
The double-circuit vacuum system of the machine is monitored by two vacuum stats which, via LED
lamps, give a signal if the vacuum is insufficient for safe lifting.
•
LED lamps show which cylinder is active.
•
Intelligent overload protection shows when the machine reaches the limits of its capacity.
Safety test (before lifting)
The window robot must be safety-tested daily before use. This test must be carried out without load.
Important!
If any of the items do not pass the safety test, the machine must not be used!
•
Carry out an inspection to ensure that the mechanical parts of the window robots are not worn or
damaged to such an extent that the safety of the machine is compromised.
•
Check the window robot vacuum system for leaks:
Leak test process
Place all suction cups on a level, dry and airtight surface (e.g. a window). Start the Winlet 350TH at
the on/off button and wait until the red lamps go out on the operating panel. Now activate the
vacuum by engaging both buttons on the operating panel at the same time. Both vacuum meters
now show the current vacuum in each vacuum circuit. Once a full vacuum has been achieved in both
circuits (a vacuum level of approximately 75%), turn the Winlet 350TH off again at the on/off
button. Now look at both vacuum meters; the vacuum level must not drop more than 10% in the
course of 5 minutes.
If the vacuum loss is greater than 10% in 5 minutes, check all hose connections and tighten any
connections as required. Check the condition of the suction plates. The seals must not show any
signs of scratches.
