Precautions when using the tool set

Jack and the chain hoist are the two tools inside the tool set. Because the jack has the tool to lift heavy objects without auxiliary equipment, and the jacking is slow, uniform, stable, and suitable for sample equipment installation deviation and object variation, so it is widely used in installation and construction. A chain hoist (also known as an inverted chain) is a small lifting tool that does not require bottom padding to be fixed and can lift heavy objects in space in any kind of the desired position. The following is a detailed description of the two tools of note.

Here is the content list:

l Jack

l Chain hoist

Jack

As the jacking tool and jacking heavy contact points are small and rely on the bottom sit flat, solid, and also provides for good contact with heavy objects, so the use of the following issues should be noted.

(1) Because of the jacking tools more types, models are complicated, the use of the necessary familiarity with its jacking performance, characteristics, and usage.

(2) Keep the jack clean, should be placed in a dry, dust-free place. Do not be in the wet, dirt, open-air storage, should be used before the jack clean, and check the piston lift and whether the parts and flexible and reliable, oil injection and whether clean.

(3) The use of hydraulic jacks, prohibit staff to stand in front of the jack safety bolt, the safety bolt is damaged shall not be used.

(4) Jack tool should be vertical with the top object and contact surface to be good.

(5) jack jacking heavy objects can not be placed for a long time regardless, and can not do deposit objects with

(6) Jack tool should be placed at the use of flat, solid, such as uneven or soft ground in the soil, should be laid with a certain strength pad. To keep the jack and the weight of the contact surface solid, its contact surface should be padded with a wooden board.

(7) Shall not be in the jack handle on the receiver, or with her anyway to lengthen the length of the handle.

(8) Jack jacking height shall not exceed the limit mark line, such as no marked line, shall not exceed the screw rod buckle or piston height 3/4. spiral thread or rack wear up to 20% prohibited.

(9) To pay attention to the jacking process safety operation, when jacking heavy objects, should first slightly jack up some, and then check the bottom of its jack and whether it is stable and flat, slightly tilted necessary to re-adjust, until the jack and the weight are vertical, smooth, solid, before continuing to jack up. Production or to a certain height should be padded under the weight, in place after the weight pad.

(10) Jack down should be slow, do not open the throttle will be a sudden drop, rack jack should also do, to prevent a sudden drop led to shaking jump and hurt people.

(11) Several jacking tools synchronous jacking a heavy object, there should be a person to direct, to maintain the lift synchronization, to prevent uneven force, the object tilt and accidents.

Chain hoist

It can not only be used in the installation but can also be used to tighten the cable and huge equipment delivery fixed, can also be used for alignment, find the right, etc.

Chain hoist tools should be used with attention:

(1) The use of chain hoist tools must be the official manufacturer of qualified products.

(2) Used, old chain hoist, before use should be done in detail to check, such as hooks, chains, etc. and whether intact, lifting chain root pin and whether it is in line with the provisions of the transmission of certain and whether flexible, lifting chain and whether the wrong twist, self-locking and whether effective, the parts and whether there are cracks, deformation, serious wear, and tear, etc.

(3) The use of the chain, such as the occurrence of stuck, the weight should be well padded before overhaul.

(4) Chain hoist tool in any direction of action, hand zipper direction should be consistent with the direction of the sprocket, pull the chain with even force, not suddenly and violently pull.

(5) Operation, the hoist shall not stand below the person.

(6) Prohibit the use of overload, the operation should be by the hoist lifting capacity to determine the number of zippers, ordinary lifting capacity of 5t as follows to allow 1 person zipper, more than 51 to allow two people zipper, can not pull the factors to identify, to prevent the object stuck or machine failure of accidents.

(7) Lifting objects such as the need to stay high for some time, the hand flap chain should be firmly tied to the lifting chain for insurance, and to have a safety rope to prevent self-locking failure.

(8) The chain hoist tool shall not be used to deposit heavy objects or equipment at high places.

(9) Chain wear of 15% or more is prohibited to continue to use.

(10) Do not penetrate the lubricant into the friction piece to prevent self-locking failure.
