Why can t the inverted chain go up and down, and why can t the inverted chain fall back?

1.After use, the gourd should be cleaned and coated with anti-rust grease, and stored in a dry place to prevent the chain block from rusting and corrosion due to moisture. 2.

Maintenance and overhaul should be carried out by those who are more familiar with the hoist mechanism, clean the hoist parts with kerosene, and add butter lubrication to the gear and bearing parts to prevent those who do not understand the performance principle of the machine from disassembling and assembling at will.

3.After cleaning and maintenance, the hoist should be tested at no load to confirm that it works normally and the brake is reliable before it can be delivered.

4.The friction surface of the brake must be kept clean. The brake part should be checked frequently to prevent brake failure and heavy objects from falling from occurring.

5.The rollers of the left and right bearings of the lifting sprocket of the chain block can be adhered to the inner ring of the bearing that has been pressed on the journal of the lifting sprocket with butter, and then loaded into the bearing outer ring of the wall plate.

6.When the chain block is installed in the braking device part, pay attention to the ratchet tooth groove and the pawl part of the pawl part meshing well, the spring control of the pawl should be flexible and reliable, after installing the hand sprocket, rotate the hand sprocket clockwise, press the ratchet wheel and friction plate on the brake seat, rotate the hand sprocket counterclockwise, and there should be a gap between the ratchet wheel and the friction plate.

7.In order to facilitate maintenance and disassembly, one of the sections of the hand chain is an open chain (not allowed to be welded).

Lubrication is fine, it should be rusty.

Because the brakes are locked, just shake off your hand and pull even to turn on the brakes.

Summary. Hello, the reason why the bicycle inverted chain (inverted chain) does not go: the rear wheel of most bicycles adopts a one-way transmission mechanism with ratchet ratchets.

This structure is also called a flywheel. When the chain drives the flywheel, the clockwise selection ratchet mosh, the ratchet meshes with each other, and drives the rear wheel to rotate. When the chain drives the flywheel to rotate counterclockwise, the ratchet slides through the ratchet and does not engage, and the flywheel idles.

Therefore, the bicycle is not allowed to walk when the chain is reversed.

Hello, the reason why the bicycle inverted chain (inverted chain) does not go: the rear wheel of most bicycles adopts a one-way transmission mechanism with ratchet ratchets. This structure is also called a flywheel.

When the chain is driven by a de-section, the flying and wheel timing are selected to mosh, and the ratchet ratchets mesh with each other to drive the rear wheel to rotate. When the chain drives the flywheel to rotate counterclockwise, the ratchet slides through the ratchet and does not engage, and the flywheel idles. Therefore, when the chain is reversed, the bicycle cannot be walked.

Hello, first of all, first stop using rotten rang liters immediately, and then check whether the chain part of the inverted chain is old and damaged or whether the chain has kinks that cause the chain to be stuck; Check whether the surrounding objects are stumbling on the heavy objects being lifted; Check whether the object being lifted has exceeded the rated load weight of the inverted chain itself; Check whether the chain is directly trapped to lift heavy objects (the chain cannot directly slide and bundle heavy loads); In the end, it can only be used for a single inverted chain.

Hello, manual hoist, also known as fairy gourd, catty does not fall, chain hoist is a kind of manual hoisting machinery that is simple to use and easy to carry, also known as chain hoist or inverted teaser chain. It is suitable for short-distance lifting and hand transportation with small equipment and goods, and the lifting capacity is generally not more than 10t. The chain hoist has the characteristics of compact structure and small hand pulling force.

There are several main reasons why the linked list can't go back: 1. The linked list is looped and walked backwards: the ring of the linked list will prevent "going backwards", that is, it is impossible to find the starting point of the linked list through the unlinked list, resulting in the inability to reverse it.

2. Lack of necessary markup: Ordinary linked lists usually have a flag bit (such as the next pointer) to indicate "next", while the reverse linked list lacks similar indicator markers, which makes it impossible to determine the next step to **, resulting in the inability to reverse. 3. The number of linked list nodes is inconsistent

Suppose there are 10 nodes in the linked list, as long as any of the nodes are more or missing, there may be a situation where "the hail does not go back". Therefore, the reason why the inverted link cannot be reversed is mainly due to the characteristics of the ring list, as well as the lack of necessary tags and the inconsistent number of linked list nodes.

Hello dear. If the chain cannot be reversed after the chain is reversed, there are several reasons: 1. Chain problem:

Check if the chain on the chain is stuck or damaged, if the chain is stuck or damaged, it will cause the chain to not fall back properly. 2. Tension problem: After the chain is reversed, the chain may not be able to reverse due to excessive tension.

Trying to reduce the tension of the chain may require adjusting or replacing the chain tensioner. 3. Chain damage: Check if the chain is damaged or twisted, if the chain is damaged, it may cause the chain to fail to reverse back.

Damaged chains need to be replaced. 4. Chain attack state assembly problem: check whether the chain is closed and installed correctly.

If the chain is not assembled correctly, it may cause the chain to fail to reverse upside down. Make sure the chain passes correctly through the gears and transmission, and that the chain length is appropriate for your vehicle. If none of the above methods work, it is recommended to send your bicycle to a professional bicycle repair shop for inspection and repair.

They will have more professional equipment and experience to solve the problem of chain inversion.

Summary. Hello, dear, the reason why the inverted chain can only be pulled in one direction is that if the oblique pull oblique bor is carried out when driving the inverted chain, it will not only cause great wear and tear, but also very likely to cause the chain to derail, and there may also be a chain jam. Cause Analysis:

Hello, dear, the reason why the inverted chain can only be pulled in one direction is that if the oblique pull oblique Bo is carried out when driving the inverted chain, it will not only cause great wear and tear of the Liminna, but also very likely to cause the chain to derail, and at the same time, there may be a situation where Huaijing may be stuck in the chain. Reason analysis: This adjustment of the pulling leg without direction makes the inverted chain more convenient to use, and can be competent for more lifting operating environments.

Inverted chain is also known as "chain hoist", chain block is a manual lifting tool that is easy to use, easy to carry or easy to pin. The principle of the wheel axle is used, so as to play a labor-saving role. It is suitable for installation operations in factories, mines, construction workers' collapsed grounds, docks, ship berths, warehouses, etc., and has more important functions for open-air and non-electric operations.

Operating procedures for the safe use of inverted chains.

1. Use inverted chains not to overload.

2. When using the inverted chain, it should be slowly tightened first, and it needs to be checked before lifting. When the inverted chain cannot be pulled, it is not allowed to be deadlifted. Pull the small chain with even force. When using, do not twist the zipper.

3 When lifting an object with an inverted chain, if the object needs to be temporarily suspended in the air, the zipper should be sealed.

4. It is strictly forbidden to use the inverted chain with broken marks, cracks, elongation and severe corrosion.

5. The inverted chain shall not be in contact with chemical media and dirt in use, and shall be carefully maintained, and hung in a dry room when not in use.
