Knowledge of lifting machinery

Strictly implement safety operation specifications

Lifting machinery refers to the electromechanical equipment used for lifting or lifting vertically and moving heavy objects horizontally. Cranes as large as several thousand tons and gourds as small as several hundred kilograms are all in this category.

As one of the eight special equipment second only to elevators and pressure vessels, lifting machinery is essential for the continuous expansion of industrial production scale, but it is inevitable that there are still many dangerous factors before and after use, which brings a non-negligible threat to people's lives and property. Today we will take a look at the lifting machinery in the operation of what matters for attention!

PART·1

Safe operating rules for crane operation

pre-job

First, the driving operator is on duty with a certificate.

2. Confirm that no one is in the driving working area.

Third, confirm that there is no fault alarm.

4. Wear safety protective equipment correctly

In operation

First, before starting, it must be confirmed that the site environment is safe.

Second, before starting, a warning signal must be issued, and the crane must not be inspected and maintained during work.

Third, overload or the weight of the object is not clear, shall not start, must be adjusted in the case of load, the brake of the lifting and amplitude changing mechanism.

Fourth, the structure or parts have defects or damage that affect the safety work, such as brake, safety device failure, hook nut anti-loose device damage, wire rope damage to reach the scrap standard.

Fifth, the binding, hanging is not strong or unbalanced and may slide, the weight is not padded between the corners and the wire rope.

6. If there is a person or a floating object on the object to be lifted, it shall not pass above the person or under the arm of the lifting.

7. Shall not use the limit position limiter to stop.

8. When the lifting weight is close to or reaches the rated lifting capacity, the brake should be checked before lifting, and the suspension should be carried out after a small height and short stroke test lifting.

9, no falling limit of the crane, the hook in the lower working position, the steel wire rope on the drum must maintain the design of the number of safety rings.

10, for the crane without reverse braking performance, except for special emergencies, shall not be used to brake the reverse car.

Emergency measure

First, after the object strike accident, the injured should be immediately organized to rescue, according to the injury situation for disposal.

Second, when mechanical injury occurs, the danger source should be cut off first, to prevent secondary injury, and to dispose according to the injury situation.

Third, when electric shock occurs, cut off the power supply so that the electrocuted person can get rid of electric shock as soon as possible.

Fourth, in the event of falling injury from a height, the injured should be bandaged, hemostatic and fixed, and be handled according to the injury situation.

PART·2

Safe operation ten no hanging

1. No lifting over rated load.

Second, the work site is dim, can not see the site, the initial lifting or command is not clear.

Third, the rope and accessories are not firmly tied, do not meet the safety requirements.

4, hanging heavy objects directly processed without hanging.

Five, crooked pull oblique hanging.

6, the workpiece stands on the person or put moving items do not hang.

Seven, oxygen cylinders, acetylene cylinders and other explosive dangerous items do not hang.

Eight, with edges and corners, fast mouth not cushion good not hanging.

9, weight unknown not hanging, buried in the ground is not hanging.

10, the management of illegal command does not hang.

PART·3

Matters needing attention

First, lifting machinery use units should often check the operation and good condition of lifting machinery, regular maintenance of lifting machinery. This includes annual, monthly, weekly, and daily inspections.

Second, when the lifting machinery is found to have abnormal conditions, it must be handled in time, and it is strictly prohibited to run with illness.

Third, the lifting machinery use unit must apply for lifting machinery safety technical inspection one month before the validity period. The regular supervision and inspection cycle of lifting machinery in use is two years.

4. The drivers, hook workers, command workers and maintenance workers of lifting machinery must undergo professional and technical training, pass the examination of the municipal special equipment safety supervision and management department, and obtain the "Special Equipment Operators Safety Operation Certificate" before taking up the post.
