d ) only gantry and semi gantry cranes are equipped with anti-wind tongs

#3. Whether the operator can lift the load being moved when the cables of the lifting mechanism of the hoist, winch, crane are not vertical:

a ) yes, provided that the angle of deflection of the ropes does not exceed 45°

b ) yes, provided that the angle of deflection of the ropes does not exceed 60°

c ) yes, because the maximum allowable angle is 120°

a ) Fig A, B, C

b ) Fig A, B, D

c ) Fig A, C, D

#5. A complete check of the lifting mechanism brake consists of:

a ) lifting a load weighing no more than the nominal lifting capacity of the device to a height of 2 m, and then lowering it in a downward direction and stopping abruptly

b ) lifting a load weighing no more than the nominal lifting capacity to a low height so that the load loses contact with the ground and observing whether the load does not spontaneously fall, and then lifting it, lowering it, and stopping it abruptly

c ) to actuate the lowering mechanism without the suspended load in the downward direction and observe whether the shear will stop before it touches the working level

d ) to actuate the lowering mechanism without the suspended load in the upward direction and observe whether the shear will stop before it touches the working level

#6. The directions of travel in a radio-controlled crane should be marked:

a ) on the crane structure in a place visible to the operator and on the radio control remote control

b ) in the crane cabin

c ) in front of the entrance to the hall where the crane is working

d ) on each visible track support pole

#7. Absence of the maintainer from the examination of the technical device requires min:

a ) prior agreement with the authority of the relevant technical supervision unit

b ) provide a written excuse for the conservator's absence

c ) presentation of a medical release confirming the conservator's inability to work

d ) all answers are correct

#8. Decision issued by UDT:

a ) is not subject to appeal

b ) may be changed by the PIP inspector

c ) is subject to the possibility of appeal by the operator

d ) each answer is incorrect

#9. WLL stands for:

a ) weight load limit

b ) permissible working load of the tendon at an apex angle of alpha 120°

c ) manual operation allowed

d ) technical and operating documentation

#10. Lifting loads with two or more UTBs:

a ) is permissible, provided that the operator develops detailed operating conditions describing organizational and technical activities that minimize the risk

b ) is always permissible if the weight of the load does not exceed the sum of the lifting capacities of the equipment used

c ) is allowed if the weight of the load does not exceed half of the lifting capacity of each device used

d ) is never allowed

#11. Which of the lifting accessories shown can be used to lift steel bars of considerable length:

a ) FIG. 1

b ) FIGURE 2

a ) is punishable by a fine or restriction of liberty

b ) is subject to a criminal fine

c ) is not subject to a penalty

d ) all answers are incorrect

#14. An important criterion for hook wear is:

a ) rupture

b ) hook throat opening

c ) reduction of the cross-section in the grip part

d ) all answers are correct

#15. The scrapers are:

a ) elements used to prevent foreign objects from getting under the wheels of the crane

c ) elements used to protect the crane from unintentional movement

d ) protective elements of the track structure
