Explosion-proof electric chain hoist is a kind of "explosion-proof" electric chain hoist, which can be divided into gas explosion-proof hoist and dust explosion-proof hoist according to the use environment. According to the mounting type, the explosion proof electric chain hoist can be grouped in trolley type explosion proof hoist & hook mounted explosion proof chain hoist . The trolley type explosion proof electric hoist is used on on H beam or I beam to transfer loads from left and right with a motorized trolley or manual trolley, and with a hoist hook to lift up and down . And the hook suspension explosion proof chain hoist is a stationary type electric chain hoist, which is anchored by a hook in a place with the lifting hook to lift loads up and down.

The explosion-proof electric hoist are made of special non-sparking materials, which will not produce mechanical sparks when they rub against each other during operation, and will not detonate gas in flammable and explosive places, effectively preventing fire accidents and ensuring customer property and personal safety.All in all, the explosion proof chain hoist is also spark proof hoist, flame proof hoist, and safe hoist in hazardous applications.

• Clutch: As an emergency overload protection, the clutch will function and the motor will slip if an abnormal load is applied.
• Cooling fan: A cooling fan prevents motor overheating when used continuously for an extended period of time.The hollowed-out fan cover and cooling fin not only improve fan heat dissipation capacity, but also make the fan run more quietly.
• Limit switch without guide frame: The absence of a guide frame ensures that the hoist lifts and drags the weight diagonally.
• Aluminum shell: Except for the connecting case, all other parts of the hoist body are made of aluminum, which is light in weight but has exceptional rigidity, as well as high dust and water resistance.
• Magnetic force generator: The magnetic force generator is the most recent design that is featured for generating magnetic force. It allows for immediate braking as soon as the electric power is turned off. As a result, braking safety while loading is ensured.
• Dual rates Hoists with built-in inverters: Use a built-in inverter to power the hoist. Dual speeds reduce swing in operation, allowing the hoist to start steadily and stop slowly. The speed ratio can be adjusted; the standard speed ratio is 4:1; if you have any special requirements, please let us know when you inquire.
• Advantages of an anti-phase protector: When a power-supply wiring error occurs, the control circuit is unable to move, preventing the motor from being burned.
• Hooks: It is hot forging with perfect strength and is difficult to break.The lower hook's operation safety is ensured by its 360-degree rotation and safety tongue piece.
• High-quality chain:It is made of ultra-strong heat-treated alloy steel imported from Japan.
• Advantages: It is approximately safe when used in rain water, sea water, under chemical and other adverse conditions.
• Using a hand switch: Hand switch operation is made easier by an ergonomic shape design. The button with a light, soft operating sensation ensured that the operator did not become fatigued after a long period of operation.

Features of explosion proof electric chain hoist

• Low profile design, higher lifting. The lifting height of the electric chain hoist can be increased by 200 ~ 500mm, compared with ordinary CD /MD electric chain wire rope hoist.
• Excellent three-in-one transmission technology, the hoisting reducer is made of high-quality alloy steel, with three-stage deceleration, stable operation, long life and reliable performance, avoiding many shortcomings of long-distance transmission of CD hoist intermediate shaft.
• The motor is a specially designed new self-cooling cone type motor. The motor shell is made of aluminum alloy material with good heat dissipation performance. The motor insulation grade is F grade and the protection grade is IP54, which is one grade higher than ordinary motors.
• The electrical components are from Schneider , using large-capacity contactors and other components. The connection between the control switch and the motor and electrical components uses quick plugs, which makes on-site installation faster; the cables of each leakage part of the explosion proof hoist are protected by PE bellows to ensure reliable cable connection. .
• The spark proof hoists can be customized according to user requirements in terms of hoist operation, hoisting speed either single spepd, double speed or variable frequency stepless speed , hoist control either remote control operation or pendant control operation, overload protection, motor overheating protection and other functions, etc.

Advantages of explosion proof electric chain hoist

The structure is exquisite, the appearance is beautiful, and it has many unique advantages:

• The main body of the exproof electric chain hoist has no leaking cables, and the cables are arranged inside the exproof electric chain hoist by various means, so that the appearance of the exproof electric chain hoist is more beautiful; for example, the supporting shaft is a hollow thick-walled steel pipe. The overall weight of the electric exproof electric chain hoist is reduced, and the cables of the left and right parts of the exproof electric chain hoist can be passed through it.
• The structure of the exproof electric chain hoist is compact, and the counterweight is a counterweight box type. Users can add various scrap steel or stone materials, etc., which saves steel and reduces the external size compared with the counterweight block type low-headroom electric exproof electric chain hoist;
• The operation of the exproof electric chain hoist is driven by the NF series helical gear reducer. The driving wheels on both sides transmit the torque through a hexagonal steel, which has large transmission torque and high reliability, avoiding the failure of the flat key shearing. It is very beneficial to the installation and adjustment of the running part of the exproof electric chain hoist;
• The outer cover of the exproof electric chain hoisting main engine is a square welded structure with mounting bolt holes on all sides, which is highly versatile and can be quickly changed to a fixed or suspended trolley-operated electric exproof electric chain hoist, and the rope can be drawn in a 360° direction.
• The whole structure is easy to disassemble and install, convenient for maintenance and good maintainability.

Safe operation of explosion proof electric chain hoists：

• Select the appropriate type of electric explosion proof hoist to avoid overloading.
• Check the chain fall explosion proof hoist before use to see if there is any wear, nicks, etc., if any, replace it in time.
• The operator must wear the corresponding dustproof protective gear to avoid adverse effects on the body caused by the special environment.
• When the electric explosion proof hoist lifts heavy objects, the heavy objects should be hung at the center of gravity of the hook to avoid the phenomenon of heavy objects falling.
• When ex-proof hoist lift heavy objects, do not explosion proof hoist it obliquely, so as to avoid shaking of the heavy objects and aggravate the chain load.
• Make heavy objects rise at a constant speed, do not rush for success.
• When explosion proof hoisting, people should not stand under the dropped heavy objects to prevent the heavy objects from falling and causing danger.

For the use of dust explosion-proof electric explosion proof hoists, it is necessary to standardize. It is necessary to read the instructions before using the equipment, and then start work after familiarizing yourself with the equipment and specifications to avoid accidents.
