Fixed Chain Hoist

Fixed electric chain hoists, also called hook type chain hoists, are the most widely used material handling solutions. With the proper fixed electric chain hoist, we are able to lift and move the heavy objects and loads at the press of a button. With proper fixed chain hoist, we are able to work with more efficiency, saving more energy, time and money in some extend. With proper fixed electric chain hoist, we are able to make our working environment with high safety and saves life, living a more enjoyable life.

Hook type Electric Chain Hoist Structure Features:

• Chain hoist shell: The cooling fin is especially designed to ensure quick heat dissipation with rate up to 40% and continuous service. The shell of the electric chain hoist is made of die-cast aluminum alloy, light but hard.
• Chain hoist motor: Dongqi electric chain hoist adopts the Side Magnetic Series YEP Braking Motor.
• Chain hoist gear: The hoist gear of the electric chain hoist is made of alloy steel by carburizing quenching treatment. Thus transmission with low noise and high efficiency is guaranteed.
• Inverse phase sequence protecting device: Inverse phase sequence protecting device is used to cut the circuit of the electric chain hoist in case of wiring error in the power supply.
• Side magnetic braking device: The magnetic force generator is the latest design which is featured for generating magnetic force. It makes electric chain hoist instantly braked as soon as the electric power is cut off. Thus the braking safety while loading is guaranteed
• Electromagnetic contactor: Electromagnetic contactor can be used safely under high frequency.
• Control switch: Waterproof push button is applied to electric chain hoist. It is light and durable.
• Limit switch: The limit switch device is installed where the weight is lifted on and off to make the motor to stop automatically so as to prohibit the chains from exceeding for safety
• Chain bag: The chain bag of Dongqi electric chain hoist is light, attractive and durable.
• Lifting Chain: The lifting chain of Dongqi chain hoist usually adopts FEC G80 ultra heat-treated alloy steel chain, which also can be safety in poor environment such as rain, sea water and chemicals.
• Hoist Hook: The lifting hook of electric chain hoist is forged with perfect strength which is hard to break. The operation safety of the lower hook is ensured by its 360 degrees rotation and safety.
• Support frame: The loading support frame consists of two steel plates, which is extremely sturdy.
• Transformer: 24 V/36 V/48 V transformer device. This device is used to prohibit unexpected accidents caused by electric leakage and guarantees the safe use while raining.

How to Install a Fixed type Chain Hoist：

• General Precautions:

First, read and understand the manual of your fixed chain hoist. Carefully read and follow all the directions, safety instructions, and suggestions relating to chain hoist installation and its usage. It’s necessary that you check and verify the strength of the structure to that you may be attaching the unit. Carefully examine the hooks, chains, pulleys, brakes and limit switch to make sure they are properly working and take away or repair the broken and exhausted components. The chains should be properly oiled. Don’t attempt lifting the load that weighs over the capacity of the chain hoist as falling or dropping of its components will cause injury and property damage. Support the hoist adequately throughout the installation.

• Installing the Bolt Shackle:

Make sure you are using a rated bolt shackle, remove the bolt and fit it into the mounting point with the shackle. Tighten the nut back in place and make sure you replace the safety pin. Make sure the bolt shackle is resting on the bolt before installing the unit.

• Suspension of the Chain Hoist:

On the chain hoist, first, open the safety latch located on the top hook. Slide the hook onto the shackle in the direction you want the unit to be. Make sure you release the safety latch after the installation. It’s important to confirm that the security latch isn’t open, an open safety latch may result in slipping of the chain hoist from the shackle whereas the load is being raised.

• Operational Checks:

When you finish with the installation, test the chain hoist and ensure that is properly working. Test load the unit by raising and lowering the load a number of times before putting the unit on service, this may help you to detect and correct any defect or malfunction the setup may have.
