Technical Data High-speed lifters Zip Chain Lifter Handling
Operation/Inspection procedure
This section describes the general handling of ZIP CHAIN LIFTER.
For details, please refer to the instruction manual included with the product.
Operation
- ・The three-phase motor is supplied with temporary cable (for power and brake). When operating ZIP CHAIN LIFTER for the first time, do the actual wiring after raising the table frame by temporary cable. Do not use temporary cable for actual operation.
- ・Always use ZIP CHAIN LIFTER within the allowable load and the allowable lifting speed. Exceeding either of these ranges may damage the lifter.
- ・Under no circumstances should the lifter be used out of nominal stroke, even when operating with no load. Exceeding the nominal stroke range may damage the lifter. Do not subject the lifter to sudden impacts under any circumstances.
- ・Ensure that foreign substances such as dust and hot chips do not attach to or enter ZIP CHAIN or any other movable components or detection units. Such substances will accelerate wear in the unit and may lead to serious trouble such as chain fracture or damage to moving parts. Take appropriate measures to prevent foreign particles from entering the lifter.
In addition, use a safety fence around the lifter to prevent entry into the space under the table frame. - ・Be sure to design the sequence circuit so that the holding brake of the motor operates to prevent the load from dropping when operation is stopped.
- ・Never use the lifter with contact stop. Using the lifter with contact stop may cause serious damage to the lifter.
- ・Some areas of the lifter may become hot. Keep hands or any other part of the body from coming in contact with such areas.Failure to do so may result in burn injuries.
- ・Stop operation immediately if an error occurs.Failure to do so may result in electrical shock, injury or fire.
- ・Do not use the built-in mechanical brake for stopping even in an emergency. Be sure to use control logic that activates the mechanical brake after deceleration by the dynamic brake. For details, refer to the motor manufacturer's instruction manual.
Inspection
1. Ensure safety during maintenance and inspection, and always use the maintenance bar.
Always use the maintenance bar during maintenance or inspection below the table frame.
Failing to prevent the table frame from falling down may cause serious injury or death.
Remove any load from the lifter.
Be sure to remove the maintenance bar when restarting operation.
※Never modify the maintenance bar. Modification may lead to serious accidents.
Holding the table frame using a crane will be a fail safe.
2. Inspect ZIP CHAIN (Every 1 months )
- (1)Remove any objects being conveyed.
- (2)Implement fall prevention measures to ensure the lifted portions do not fall.
- (3)Check the entire length of ZIP CHAIN for the following.
- ・Abrasion powder (reddish-brown) coming from between the plates
- ・Abrasion powder (reddish-brown) coming from around the chain rollers
Lubricate the chain immediately if either of the above are found. - ・Broken rollers
- ・Chain roller roughness caused by wear, noticeable by touch
Discontinue use and contact a Tsubaki representative if either of the above are found.
3. Greasing
See the following table for detailed lubrication information.
| Use classification | Lubrication method | Recommended lubricant name | Lubrication cycle |
|---|---|---|---|
| Zip Chain | 10 to 15g per 100mm of stroke | Class 1 No. 2 high-load grease or equivalent Shell Albania EP Grease 2 (Shell Dolium Grease) |
Every 3 months or 100,000 trips |
| Roller travel rails | Brush on an appropriate amount | ||
| Roller | Appropriate amount applied with grease gun |
(Lubricating ZIP CHAIN )
Follow the steps below to lubricate ZIP CHAIN.
- [1]Remove any objects being conveyed on the table frame.
- [2]Implement fall prevention measures to ensure the lifted portions cannot fall.
- [3]Lubricate all rollers as shown in the figure to the right.
(Lubricating the travel rails and rollers )
Apply grease to the traveling surfaces of the rail (both top and bottom).
After lubricating, run in the chain and remove any excess grease before starting operation.
