5.9. Lifting of men (load) aboard helicopter in hovering by hoist with nnr-150M winch
(1) Give the following order to the Flight Engineer: "Put safety belt on, open
cargo compartment entrance door and prepare for operation of hoist
boom".
(2) The Flight Engineer should proceed as follows below:
(a) Take the station near the cargo compartment entrance door upon
the Captain's order.
(b) Connect the headset receptacle to the interphone selector panel at
frame No. 5H. Set the ON - OFF (BKn - BbIKn) microphone switch,
located on the interphone selector panel to ON (BKn).
(c) Switch the MOTOR 1 (nEPBblll1 ,QBlI1rATEnb) and MOTOR 2
(BTOPOll1,QBlI1rATEnb) circuit breakers, located on the nnr-150M
winch control box, on.
(d) Put the safety belt on, insert the retainer pin into the safety belt lock
and attach the safety belt cable snap hook to the ring at the strap.
The other end of the cable should be attached to the fitting provided
at the web of frame No. 5H.
(e) Open the entrance door, set the hoist boom to the operating posi-
tion and report readiness for operation to the Captain.
(3) Hover over the area from which lifting will be perforrned·so as the
clear~
ance above the person (load) to be lifted is 6 to 15 m. If surrounding ob-
stacles are present, hover at a height ensuring a clearance not less than
3 to 5 m above the obstacles (the load up and down travel should not ex-
ceed 40 m).
Give the following order to the Flight Engineer: "Unreel hoist boom ca-
ble".
(4) Upon the Captain's order the Flight Engineer extends the winch cable un-
til the grounding cable touches the ground to prevent the ground person-
nel exposure to static electricity. As this takes place, the main cable
should remain tensioned, this condition being ensured by a weight of 5 kg
provided by the construction.
Notes: 1. To avoid injury to the person (damage to load) being lifted by
the cable hook, extend the cable aside of the person (load).
2. When the hook loaded by the 5 kg load touches the ground,
this condition being indicated by slackening of the cable, the
nnr·150M winch stops the extension of the cable automati-
cally.
