Subject to inspection:

• executive body of the brake, the serviceability of the rods, the presence and tightening of locknuts on the rods and adjusting joints;
• fastening brake liners with pads;
• the condition of the hinged units of the brake system of the lifting machine;
• the gap between the brake shoes and the brake rim of the drum is checked. This gap should be 0.8 mm on each side (no more than 1 mm);
• the oil level in the oil tank and the alternate operation of the oil pumps and the pressure reducing valve are checked. The pressure of the manometer of the reducing valve should be 11-12 kg/cm 2 , the pressure of the pressure gauge on the safety valve 11-12 kg/cm 2 ; For lifting machines Ts2×1.5, the pressure of the pressure reducing valve pressure gauge should be 8-10 kg/cm 2 , the pressure of the pressure gauge on the safety valve 11-12 kg/cm 2 . The pressure on the service brake actuators must be within 8-10 kg/cm 2 .

During the bypass and inspection, the oil filter handle is turned. The pumps must be in operation alternately. The pressure on the service brake drives should be within 11-12 kg/cm 2 .

• check the gap between the heads of the thrust bolts under the brake pads 4-5 mm;

• the condition of the couplings, the absence of leakage of the filling lubricant and the condition of the fingers on the finger couplings are checked;
• checking the gearbox is reduced to checking the attachment points to the frame, the presence and level of lubrication in the crankcase at the dipstick mark, the presence of oil leakage from the gearbox. During operation, the heating of the bearings of the gearbox and the main shaft is controlled. It should not exceed 70-80 0 C.
• checking email status. motor, the stator temperature should not exceed 55 0 С.
• on the control panel, the ease of movement of the control handles, their fixation, the presence of marks on the depth indicator and devices for monitoring the working processes of the hydraulic system and electrical devices that are part of the equipment and the machine are checked.

When accepting and handing over a shift, the presence of protective equipment is checked: gloves, boots, a voltage indicator, the presence of posters for performing work in electrical installations, the presence of a lifting scheme, an alarm, a brake system and check logs for a leak relay, a hoist, ropes, a shift acceptance and delivery log.

Checking protections and interlocks, brakes on a stopped machine.

After external inspection, 220V voltage is applied to the control circuit for switching on the operational voltage. Then, by turning on the KRU-RN cell, we apply voltage to the reverser.

• turn on the oil station pump on the control panel and watch the pressure gauge readings so that the oil pressure in the brake oil system is 12 atm., if necessary, switch to the backup oil pump by switching the package switch to the ShSU and the button on the control panel.
• we check the emergency shutdown button by pressing the foot button - the KRU-RN cell should turn off
• when the safety brake is applied, push the service brake handle “away from us” to the “disengaged” position, while the service brake should not be released.
• check the blocking of the PT with a service brake, the zero position of the command device, the serviceability of the dynamic braking circuits, the serviceability of the VIK switches (shoe wear switch) and the Sk switches (rope loosening switch), which is located on the ladder course of the pulley. With the service brake handle partially disengaged or the command device handle in the reverse position, press the KZT button on the control panel, while the brake should not be charged.

The PT should not be charged when the VIK and VOK switches are pressed by hand (rope inlet on the pulley platform). By pressing the foot button and the button on the DT control panel, make sure that the DT current is present on the ammeter. In the absence of current, after 1-2 seconds, the FET should work.

• the service brake must not be released when there is no voltage in the operating circuit.

Checking the car in motion.

• Together with the signalman of the zero platform, the switches for overlifting the tub are checked. To do this, at a quiet pace (0.3-0.5 m / s), at the signal of the signalman, the tub rises up. When lifting the bucket to a height, not reaching the pile driver of 3.0 m, the PT should work. Having switched the key of the separate check of overlift by the driver and charged the TP, quietly lifts the vessel up no more than 0.5 m later, the TP should work again due to the operation of the pusher switch.

To avoid an accident, stop the overlift check when the bucket is lifted 2.3 m from the pulley platform.

• Check the bypass switch on the control panel. Charging the TP should be possible only when the switch is turned to the right, while the reverse should turn on only in the direction of the descent of the tub down.
• Check the setting of the electric speed limiter (EOS, ROS) according to the test instructions.
• Perform an idle run of the bucket down, while checking the operation of the p / m on the move, the operation of the diesel engine, the operation of the service brake (the speed should be no more than 2.5 m / s.)
• During the movement of the bucket up, the operation of the speedometer is checked.
• 15 m before the zero site, in accordance with the mark on the UGS selsyn at the p / m, the signal for the start of deceleration should ring, and after 6 m, the red lamp on the selsyn lights up, signaling the last turn of the fine countdown arrow to the end of the ascent. During the test run, all labels are checked.

It is forbidden to transport people during the trial run.

After checking the machine, the driver slows down the machine and, if the installation is in good condition, takes duty, in case of a malfunction, the driver is obliged to call a mechanic to eliminate them. Inspection of the machine should be carried out within 15-20 minutes. The shift handover and acceptance are made out in the log signed by the drivers handing over the shift and receiving the shift.

Machine control

During operation, the driver must carefully monitor the readings of electrical measuring equipment, as well as the readings of the pressure gauge. After the start of work, the driver periodically, at least every 2 hours, checks the temperature of the bearings of the drum and gearboxes, the engine, the transformation under the brushes, sparking in starting resistors.

If the instrument readings deviate (beyond the red marks), the driver is obliged to immediately brake the machine to find out the reasons for the deviation and take measures to eliminate them. It is also necessary to carefully monitor the indications of the arrows of the depth indicator. If during the movement of the bucket the arrow stops or moves in jerks, the machine must be braked and the cause found out. When the bucket approaches the horizon or zero ground, the driver must begin to slow down to 0.8 m / s and be ready to stop the machine, increase monitoring of the marks on the selsyn, ammeter, tachometer.

For 5 m before the indicated marks, the speed should be no more than 1.0 m / s, the driver must carefully listen to the movement of the machine, observe the winding of the rope on the drum and its condition. The uneven running of the machine, abnormal sounds in its mechanisms, rope jerks, the presence of smoke and burning indicate a violation in the operation of the lift. The car must be stopped immediately.

Do not operate the machine in the event of a malfunction:

• brake system
• Protection circuit equipment
• lifting rope
• Tow hitch
• pile pulleys
• When any objects get under the rope.

If these violations occur during the run, the machine must be stopped and braked with a safety brake, subsequent switching on can only be done after the faults have been eliminated.
