You just got your new Electric Chain Hoist installed and want to start using it immediately. However, make sure you check the following guidelines for a safe environment for your organization.
Read carefully what has been stated in the instruction manual provided along with the Chain hoist, making sure that each step is correctly completed and all parts are strongly fixed.
Connect main switch power to the hoist and press down push button switch. If the hook travels in the wrong direction, power supply phase is not right. Therefore, cut off power source or breaker switch, exchange any two phases of the three-phase electric power at power switch of the hoist, and then hook will travel towards the push button direction.
Refer to nameplates AB or AC on which writes upper limit or upper/ lower limit. They are attached on the hoist to tell which type of limit switch is fixed. No nameplate means that there is no limit switch.
Press down push button until bottom hook reaches the lower limit and the reverse chain stopper touches limit switch. Check if it stops at the lower limit.
In such two cases, you should check if chain spring has enough space when it is compressed.
Lift a moderate load. Press down pushbutton switches to lower and/ or lift or descend hook several times. When the button is released, the brake should immediately stop the motor from running and the weight should stop at the very position.
While pressing down pushbutton switches, press down emergency stop button and then check whether the hook has stopped running and whether the hoist works in line with push button switch. Finally, turn emergency stop button to the right, release it after it pops out. Then operate it again. If anyone step fails, check connection wire and the self-lock of the emergency stop button.
Things to create positive before installation: The electric chain hoist and trolley are prepackaged severally. first, check if the number of the hoist accords with the number of units in the invoice and if their area unit any damages occurred from the transportation or abnormal packing. Also, Check the plate and see if the rated capacity, lifting speed, lifting height, cross traveling speed in addition because the power provide is up to plain. Check if screws of prime hook set are loosed and if the chains are knotted and twisted. 1. Check the track where the hoist and trolley combo is to be mounted: The run track of the hoist adopted is the I- Beam steel. The range of width is 75-180 mm for 1T - 2T and 100-180 mm for 3T-5T. The track for running should be smooth and its swerve radius cannot but the minimum radius stipulated within the plate. the location of axle height at the tip of the track should be mounted a physical property b...
For companies requiring overhead lifting operations, taking steps to avoid crane failure is critical to ensuring the safety of workers and overall efficiency of operations. No matter the specific industry or type of job site, taking a number of simple precautions can greatly reduce the risk of overhead crane failure. Employing high-quality, reliable inspecting equipment is critical for determining whether any mechanical problems are present that may lead to accidents. Inspections should involve checking for cracks, faulty wiring, worn-out ropes, and damaged parts. Crane technicians must also make sure the crane doesn’t exceed rated capacity and that all safety devices are working properly. Initial inspection — This consists of an inspection in accordance with the original manufacturer’s recommendations, as well as documentation of the inspection. Pre-shift inspection — This consists of an inspection in accordance with crane-operator. Frequent inspections ...
