FIELD: mechanical engineering; lifting and transportation machine building.
SUBSTANCE: invention can be used in control and protection system of load-lifting cranes. Proposed system contains load pickups 1, boom tilting angle pickups 5, parameters indicator 6 and series-connected tolerable load setting unit 8, comparator 9 and actuating unit 10 whose output is connected to first input of parameters recorder 11, unit to record designed values of parameters 12, correction unit 3, load weight check unit 2, scaling unit 4, variable coefficients unit 14, change-over switch 15, boom deflection recording unit 13 and boom reach calculating unit 7.
EFFECT: improved safety of crane owing to increased accuracy of control of its parameters.
