What to do if KITO ER2 Chain Hoists make regular clicking sounds when lifting?
If your KITO Chain Hoists are making regular clicking sounds when lifting, disassemble the hoist and check the friction clutch.
What to do if KITO Chain Hoists motor does not stop automatically at the upper or lower limit?
If the motor of your KITO Chain Hoists doesn't automatically stop when reaching the upper or lower limit, replace the limit switch. Alternatively, disassemble the actuator of the limit switch for cleaning.
How to fix unclear label indication of the push button switch on KITO ER2 Chain Hoists?
If the label indication on the push button switch of your KITO Chain Hoists is unclear, clean and repair the label, or replace it with a new one. Ensure the label is securely affixed.
What to do if my KITO Lifting Systems electric chain hoist does not operate?
If your KITO Lifting System's electric chain hoist isn't working, start by measuring the voltage of each phase at the power receiving terminal to address improper source voltage. If the source voltage is improper, check the power receiving facility. Also, if the breaker tripped due to a short circuit, replace or repair the short-circuited part. For breakers tripped due to insufficient capacity, check and replace if necessary. If tripped due to over current, identify and address the cause.
Why KITO Lifting Systems does not stop normally?
If your KITO Lifting Systems hoist doesn't stop normally, it could be due to a melted contact point in the electromagnetic contactor, abrasion of the brake lining causing too long or short stopping distance, or a negative phase connection in the power cable. Check these components to resolve the issue.
How to troubleshoot abnormal noise in KITO Lifting Systems?
Abnormal noise in KITO Lifting Systems can stem from several causes: abrasion of the load chain, abrasion of the load sheave or idle sheave, deterioration of the bearing, dragging in the brake, using improper oil with a friction clutch with mechanical brake, or mechanical interference during trolley travel. Inspect these areas to pinpoint the noise source. For the friction clutch, ensure you are using the designated oil.
Why my KITO Lifting Systems electric chain hoist operates without load?
If your KITO Lifting Systems electric chain hoist operates without a load, it could be due to an open phase (single phase operation) or an overload causing the clutch to activate. Check the power supply and friction clutch.
What to do if my KITO Lifting Systems electric chain hoist does not stop?
If your KITO Lifting Systems electric chain hoist won't stop, check for electromagnetic contact point welding or fusing by manually operating the contactor to check conduction. Also, measure the resistance of the relay coil or contactor coil if there's a burnout or breakage. Damaged moving parts can also be a cause; operate the electromagnetic contactor manually to check.
Why KITO Lifting Systems operates differently from the Push Button Switch?
If your KITO Lifting Systems operates differently from the push button switch indication, it might be due to a negative phase connection in the power cable or a wrong connection in the internal wiring. Inspect these connections.
Why KITO Lifting Systems electric chain hoist does not operate without load?
If the KITO Lifting Systems electric chain hoist does not operate without load, check the power, circuit breaker, and motor. It may be due to improper source voltage, breakage or burning of control circuit faulty electrical part, or breakage or burning of power circuit failure of motor or brake.
