While electric chain hoist components are inherently resilient, they can encounter issues if not subjected to adequate maintenance and proper operation. Among the paramount safety concerns associated with electric chain hoists, particularly those of 5 tons and greater, are dropped loads. Unskilled operators, a lack of proficient technique, the use of inappropriate lifting devices, side pulling, and overloading are all potential contributors to various difficulties and can compromise safety.
If you possess an electric chain hoist and intend to incorporate it into your project, ensure a safe and seamless experience by adhering to the following crucial safety guidelines. These preemptive recommendations will not only elevate crane safety but also prevent the risk of dropped loads, thereby safeguarding your operations.
To ensure a secure operation, please verify the following settings and components meticulously:
- Verify that the electric chain hoist is securely and appropriately connected to the trolley.
- Ascertain the trolley’s presence on the beam without fail.
- Thoroughly inspect the bolt, split pin, and nut for any signs of loose fittings. If found loose, tighten them promptly.
- Test the durability of the push-button cord wire of the electric chain hoist to ensure it can withstand the required loads.
- Additionally, examine the wire for any visible damage or wear and tear.
- Confirm that the cable support is firmly installed on the support arm for maximum stability and safety.
When conducting checks on the settings or performing maintenance on the electric chain hoist, it is imperative to first switch off the power source and secure the device to prevent any unintended movement.
Before utilizing an electric chain hoist, ensure the following tests are conducted thoroughly:
Power Supply Verification
An incompatible power source can result in the hook moving in unintended directions. Consequently, it is imperative to validate the power supply prior to operation.
Upper and Lower Limit Switch Examination
Before initiating the hoist chain, meticulously inspect the functionality of both the upper and lower limit switches. Activate the power switch and elevate the hook to verify the upper limit. Subsequently, depress the down button to ascertain the proper operation of the lower limit.
Fail-Safe Brake Test
Raise a moderate load and attempt to lower the hook by pressing the down button. If the brake promptly halts motor operation and the load remains stationary, confirm that the fail-safe brake is properly installed and functioning. Note: The original text mentioned “failing brake,” which was corrected to “fail-safe brake” for accuracy.
Motion and Obstruction Check
Ensure that no obstacles impede the full-length travel of the hoist chain along the runway. Additionally, validate that the motion’s travel speeds adhere to the specified requirements.
Emergency Stop Button Assessment
While simultaneously pressing down on the operating button, depress the emergency stop button. If the hook immediately ceases operation, confirm that the emergency stop button is functioning correctly.
