 a part of the construction of 1 tl of lever levers with an under; izhoi goy prot; -; after 7 I .1 and 2. .1 also auxiliary O. and a. o one block 3 transmits the movement of the cargo cable to the counting device, and the other block 4 opens the circuit of the device. To limit the lifting of the second unit, a latch 5 is installed. The weight of the counterweight is moved along the balance arm by a reversing motor 6 by means of a worm gear 7 and a screw 8. The load is lifted by a winch 5. The electric part of the device consists of three three electromagnetic relays 10 that are actuated contacts (), as well as slide and stationary switches 12 and J3; The relay operates according to the principle of attracting the core 14 to the core 15 under the influence of an electric current. Along the large arm of the yoke of the lever arm scale, there are suitable stationary contacts 16, which are closed as the weight of the counterweight moves. The counting part of the recording device, driven by an electromagnetic relay, consists of an electric counting clock 16 together with a synchronous electrode 17 and an electromagnet 18, as well as electric curved pulse counters 19, 20 and 21. The recording device begins to work automatically from the moment it starts. the lifting of the load by the crane and, 1Nuch51 by the spring 22 as soon as the load from the hook 23 is sp t. At the beginning of the lifting of the load on the scale of the counter 19 is accumulated on an accrual basis the weight of one load. During the lifting of the load on the scale of the counting 20, the height of the lifting of the load is put off, and on the scale of the counter 21, the number of working hours of the crane is also a progressive total. The operating time of the crane is fixed on the scale of the electrical counting hours. To protect the contacts of the registering device from burning, to improve the operation of electromagnetic dc and the ability to use cash in the network, 3 ycTpoiicTBa is turned on. POWER SUPPLY: voltage switching on 127, 220 and 380 V, as well as rectifier 25. Fixing the mechanical part of the registering device the device to the design of the crane and the loading of the cargo cable of the axle1, is determined by a change in the diameter of a six-inch b.yuka 3 and the selection of gear ratio reducer | a 26, as well as a change in the length of the patient; 1ch the corombic .ia lever weight in by means of the regulator 27. On the secondary shaft of the reducer, there is a 1p disk with a lever that closes a contact on the H.eiHi img1u, 1st counter, which fixes the lifting height of the load by a crane per unit length of the rope cable. In the absence of vertical lines of the cargo cable, an additional pair of auxiliary units must be installed. The readings of the counting unit often make it possible to determine the coefficients of the crane used for time and power, as well as to calculate the operating coefficient of the crane to find out the cost of a crane change. Taking a note for a shift is produced by a lawsuit that reads the indications on the scales recorded at the beginning: ie, from the readings recorded 1x at the end of the shift.
