.-2 - shows the positivity | m | g | (, H () of the hook in the state when they received a loop of a free sling — I Mogdukruk is the node by the action of the force of the tin of the transported crap.

FIG. The position of the hook mechanism is shown in the state when the load is transferred by the crane to the place of its supply and the loose free loop of the string is thrown out of the hook mouth with a lever under the bolt of the cocked rod.

The hook consists of: nz hull / hook, power unit 2; levers 3 (reset 1) associated with the power spring /; lower iodpargene dogs 4; top free dog 5; earrings 7 and pendants 6 for a loop of stretch nostoi npogo Koinui sling.

The initial position of the lever-dumper 3 is shown in phi1 1. For the first time, they are forced by the hand up to the position until it is seized by the lower dog 4.

The automatic charging of the hook during operation is performed in the following manner.

When lifting and carrying over a zaprop: a linen load under the pressure of a loop of a free sling S (Fig. 2), the ejector lever 3 is not retracted until it stops 9. In turn, the lever moves the lower pawl 4 to the inside rear surface of the hook hook and engages it a small upper dog 5, thus preparing an unimpeded passage of the lever by dropping it. 3 To its upper position (Fig. 3).

As soon as the load touches the headquarters or the ground and the same} P1e of the sling will weaken, lever 3 will drop, the node will be lifted up by the action of spring 2 and will forcefully throw out the loop of the free end of the sling of the hook line, the encounter of obstacles from dogs . At the same time, when the lever-resetter moves upwards, the doggie 5 will be small and the big doggie 4 will be freed from the burden of the day (Fig. 3).

Then, when lifting the hook, the constant end of the sling associated with suspension 6 will be pulled out of the load and the lever 3 will start to deflect downward from this tension. As soon as they reach their intermediate position (Fig. 1), the big dog 4 will engage with it, and this will be fixed, because the ejector lever 3, which is engaged with the big dog 4, cannot be released from it. because the roller // suspension 6 does not allow the lever to descend to unor 9 and thus itself disengages the big dog 4.. Thus, the hook is delivered by the crane to the site. following loading With the initial nano-nium of its mechanism, and its working cycle will be repeated in the same order.

Prevention and Record

1. Crane hook-release, fitted with a lever lever with a spreader, a hook end pivotally mounted on a nesneem, and employees for automatically withdrawing a loop from one free end of a double-ended sling from a hook hook, when the tension of a sling is weakened when the strap load is resting on the ground or stack, as well as the ratchet locking device of the cocking lever, which means that the spring-loaded lever is made with a hingedly attached earring and suspension for the loop of the fixed end of the sling, and dinner attachment. by the end of the smaller n. Lech-levers.

2. The form of the crane hook-self-dismounting, characterized in that the locking cocked lever device is made in the form of a lower spring-loaded dog, fixed pivotally at the carrying end of the hook and passed through a slot in the body of the lever-dumper, as well as the upper free dog, also pivotally reinforced on the carrier end of the hook and interacting with either a dog or with emphasis.
