Electric gourds are light weight, small in size, compact structure, many specifications, smooth operation, simple operation, convenient use, and wide use in production.

(1) The electric gourd that is newly installed or installed after was demolished should first be tried and rotated several times. But before installation is completed, do not check the test.

(2) Before normal use, the rated load should be performed by 125%, and it should be about 100mm from the ground. 10min's static load test to check whether it is normal.

(3) The dynamic load test is based on the rated load weight, repeatedly lift and move and move the left and right movement. After the test, check the mechanical transmission part, and whether the electrical and connected parts are normal and reliable.

(4) In use, it is absolutely prohibited from being used in the case of non -allowed environments and exceeding the rated load and the number of rated starts (120 times) per hour.

(5) When installing, debugging and maintenance, it is necessary to strictly check whether the limit device is flexibleand reliable. When the hook rises to the upper limit position, the distance from the hook shell to the roller shell must be greater than 50mm (10t, 16T, 20T must be greater than 120mm)) Essence When the hook is reduced to the lower limit position, it should be ensured that the rope rope safety ring should be ensured. The effective safety circle must be above 2 turns.

(6) Press two flashlight door buttons that move the electric gourd at the same time at the same time.

(7) After the work is completed, the total gate of the power supply must be opened to cut off the power.

(8) Electric gourds shall be manipulated by a special person. The manipulator shall fully grasp the safety operating procedures, and it is strictly forbidden to crookedly pull.

(9) In the use, special personnel must be checked regularly by special personnel, and timely measures are taken in time, and measures are taken in time and carefully recorded.

(10) When adjusting the decline of the electric gourd braking, it should be ensured that the braking decline is S≤V/100 (V is the stable rise in 1min under the load).

(11) Scrap standard of steel wire ropes: The inspection and scrap of steel wire rope are implemented in CB/T5972-1986 "The Practical Specifications for the Inspection and Scrap of the Wire Rope with Lifting Machinery".

(12) The use of electric gourds must be kept enough lubricating oil, and the lubricating oil must be kept clean, and impurities and dirt should not be contained.

(13) When oil on the wire rope, a hard brush or soft wood should be used. It is strictly forbidden to directly use your hand to oil the wire rope.

(14) When the electric gourd does not work, it is not allowed to hang heavy objects in the air to prevent permanent deformation of parts.

(15) During use, if a failure is found, the main power should be cut off immediately.
