The mechanism which blocks the gates block the rotation of the drum of the rack and
pinion hoist when the safety landing gate is open (in vertical position).
The operator who uses the hoist must follow these instructions:
- After having loaded the hoist and closet the loading ramps, makes the hoist go
upwards till the landing floor, where a safety landing gate is present, by using the
pendant control at the ground level;
- The safety gate must compulsory be assembled whenever a landing at a certain
floor is needed;
-
The operator who is at the landing floor must not open the safety landing gate
before having rotated the transport drum. However the opening of the safety gate is
blocked by the gate block which till the drum has not been rotated;
- The operator must lift the lever of the drum rotation and rotate it by nearing it to the
safety landing gate;
-
After the complete rotation of the drum, unfasten the unblocking lever from the drum
and put it on the blocking box, unblocking the safety landing gate;
- The operator can open the safety landing gate (making it rotate on its left pivot)
bringing it in vertical position;
-
After the loading and unloading operations of the transport drum the operator must
close the safety landing gate before making the drum rotate. The drum can rotate
only when the safety gate is closed (otherwise the drum will block and will not
rotate);
-
The gate must be completely closed (in horizontal position) in such a way has to
make the blocking mechanism spring;
- The operator can remove the unblocking lever from the block box and hang it to the
support on the drum after having closed the safety landing gate.
- Unblock the drum rotation mechanism and bring it upwards or downwards by acting
on the proper lever.
- After the complete rotation of the drum the operator can do the uphill or the descent
of the drum to go on working.
- After the drum rotation it is impossible to open the safety landing gate since it has
been blocked by the block gate.
