Explosion-proof electric hoist Due to the special nature of the application environment and the high requirements for its own safety, before leaving the factory, it has undergone rigorous testing. The tests conducted on explosion-proof electric hoists before leaving the factory include main type tests, general tests, media tests, sampling tests, life tests, and endurance tests for each qualified explosion-proof electric hoist factory.

Style test: Through testing explosion-proof electric hoists manufactured according to specific design requirements, it confirms that the design requirements meet specific standards.

General test: Also known as factory test, this involves testing various components or equipment of the explosion-proof electric hoist during or after manufacturing to determine whether the components or equipment meet specific standards.

Medium test: A general term for various experiments that check the dielectric electrical properties such as insulation, static electricity, and withstand voltage.

Sampling test: Tests conducted on several randomly selected samples from the explosion-proof electric hoist, also used to determine whether the samples meet specific standards.

Life test: Determine Explosion-proof electric hoist 芦 Tests or evaluation and analysis of product life characteristics that determine the lifespan achievable under specified conditions are destructive tests.

Endurance test: Tests conducted on explosion-proof electric hoists under specified operating conditions for a specific purpose within a certain period (such as repeated operation, short circuit, overvoltage, vibration, impact, etc.) are destructive tests.

When the slip line of the explosion-proof electric hoist fails, many inconveniences are encountered during use.

Let me briefly introduce the installation method of the explosion-proof electric hoist sliding line.

1. Explosion-proof electric hoists are mostly installed on lines, with steel ropes placed in the middle of the lines, above the Confucius River, and the ends fixed with basket bolts.

2. The slip ring is two rings meshing together, with a little clearance to prevent the steel rope from scratching.

3. Under the traction of the motor, the steel rope is pulled with the rotating ring as the center, performing linear or circular motion.

4. One end of the rotating ring is fitted onto the steel rope, leaving the motor lead wire, and then the rubber line is fixed to the bottom of the rotating ring. The front motor can move freely. The rear end is connected to the power supply.

Explosion-proof electric hoist It is explosion-proof crane equipment designed according to explosion-proof standards, with an explosion-proof type of "explosion-proof type." The exposed explosion-proof components of the explosion-proof electric hoist are made of special spark-free materials.

Improper starting and operation methods of explosion-proof electric hoist cranes may cause accidents due to crane shaking. When the crane is running, the crane operator stabilizes the object behind the electric hoist, and runs around obstacles under the command of heavy industry. When the heavy object starts to rise and the wire rope or chain is tightened, stop, and the electric hoist should re-find the hook in the direction of the hook swing, and the crane worker should confirm whether it is hung. Do not rise too fast, and the hanging can get rid of obstacles before increasing the rising speed. The explosion-proof electric hoist should not be operated intermittently, and should be powered for a long time during long-distance operation. The hanging should be stable during operation, and should not swing or shake.
