Manual trolley electric chain hoist is a light duty electric chain fall hoist that is mounted or suspended on a manual trolley or hand operated hoist trolley, equipped on small single girder crane, overhead H Beam & I beam, monorail systems, and other rails, with lifting capacity from 500kg to 20 ton for light duty and small loads handling.
An electric chain hoist with manual trolley is a kind of common lifting equipment, which mainly consists of an electric motor, transformer, shell, chain, and pendant control. The electric chain hoists trolley from DQCRANES are manufactured in strict accordance with international standards. They are easy to operate and efficient. Compared with other lifting equipment, the chain hoist with trolley has a smaller size, lighter weight, lower noise, and higher precision.
Electric chain hoists are usually used to take the work out of lifting heavy objects. Electricity provide all power for itself to lift the loads high enough so that the hoist can move or transfer the load to another place more conveniently. It contributes greatly to strengthening productivity and efficiency when you are working. When the hoist begins to run, the trolley helps a lot in moving your load very far. And trolleys have many sizes and types, according to the difference of trolleys, manual trolley can be mainly divided into geared trolley and push trolley.
Main Components
A manual trolley electric chain hoist mainly consists of an electric motor, transformer, shell, chain, and pendant control, which is just like the motorized trolley electric chain hoist. What makes the two types of electric chain hoists different from each other is the type of traveling trolley adopted, namely, the electric motor driving trolley and the hand power trolley. Typically, manual trolley electric chain hoists are widely used when horizontal movement is not required frequently or when the load is not so heavy.
Production Features
- The hoist shell is light and sturdy, has a high heat dissipation rate, and is fully sealed for use in environments with poor working conditions.
- Reverse phase protection device: It is a special electrical device. When the power supply wiring is wrong, the control circuit cannot work.
- Limit switch: There is limit switch devices for lifting and lowering so that the motor stops automatically to prevent the chain from exceeding to ensure safety.
- Low-voltage handle switch: The handle low-voltage (24V/36V/48V) control device can prevent accidents when the switch leaks during operation.
- Braking device: Braking uses disc DC electromagnetic braking, braking torque is large, stable, rapid, and low noise.
- Chain: 80 grade super heat-treated alloy steel chain makes the chain tougher and more durable, ensuring safety during work.
- Operating device: The electric trolley is equipped with guiding devices to make the hoist run more smoothly on the I-beam.
- Aviation socket: The connection between the hoist and the trolley is safer and more beautiful.
