Contact: Wang Haibo Tel: 0592-5361110 Fax: 0592-5580710 Postcode: 361009 QQ: 13676406304 company under mechanical garage repair shop with two st / 10.5m bridge crane, specially designed for use when lifting machinery and automotive repair. Due to the maintenance of automotive engine cylinder alignment, the amount of rise and fall of the amount of electric hoist is very strict, at a certain position of the elevator amount must be small, otherwise the cylinder can not find a positive. This requires the hoist must have a jog control, but the manufacturers to buy back the hoist has this device, it is not strictly a lifting capacity, which is very convenient for the car engine maintenance. Due to the need of this practice, we have to bridge crane electrical control system is improved in the rise and fall of each electrical circuit to increase a relay 1ZJ (or 2ZJ), while adding a combination switch LK, it works is the use of AC contactors and relays energized time difference, enabling the electrical circuit diagram method modified after inching control circuit of Figure 1 modified bridge crane electrical circuit diagram shown in Figure 2 the modified one, within the dashed box for additional parts. The normally closed auxiliary contact person to the original string rising loop, the loop relay 3C rise normally open contacts and relays IZJ normally open auxiliary contact and connected, and then with LKl, 2ZJ IZJ the relay coil concatenation and people rising country path. Similarly, the intermediate relay ZZJ string normally closed auxiliary contact person to drop the original circuit, the decline 4C four relay normally open contacts and relays ZZJ normally open auxiliary contact and connected again with LK. , ZZJ coils connected in series and people rise loop. LKl, LK2 for the same combination switch with two pairs of LK to contact when they disconnect the control loop with the same general bridge crane; when the switch is closed when the combination LK LK combination switch to contacts with groups LKl, LK . Turned on simultaneously, the rise and fall in the jog loop control. 3 total stop switch works when KK control loop is closed when the main power is turned on, AC contactor coil is energized and QC due to the action, the main circuit QC main contact is closed, the total supply of the main circuit is turned on, this time main circuit and control circuit in a working state of readiness.
