Operation and inspection procedures
This section describes general handling of Zip Chain Lifter.
For details, please refer to Instruction Manuals included with the product.
driving
- ・ Temporary wiring cables (for power and brake) are attached to the three-phase motor. When initially operating Zip Chain Lifter, use the attached cables to perform temporary wiring, and then perform permanent wiring after the top panel frame has been raised. Never use the temporary wiring cables for permanent wiring.
- - When using Zip Chain Lifter, be sure to observe allowable load and allowable lifting speed. Exceeding these limits may damage the main body.
- ・Never use the lifter outside of the stroke range, including coasting, under any circumstances. Deviation from the stroke range may result in damage to the equipment. Do not subject the lifter to any impact under any circumstances.
- - Make sure that foreign matter such as dust or chips does not adhere to or get mixed in with Zip Chain, moving parts, detectors, etc. These will accelerate wear and tear, leading to serious accidents such as chain breakage or damage to moving parts. Be sure to take measures to prevent foreign matter from entering the lifter body.
In addition, install a safety fence around the lifter to prevent people from entering the space below the upper frame. - - Design the sequence circuit so that the motor's holding brake is always activated to prevent the load from dropping when the motor is stopped.
- ・Do not stop the product by hitting it against something under any circumstances. Doing so may cause serious damage to the inside of the product.
- ・The device has some hot spots. Be careful not to touch them with your hands or body, as you may get burned.
- If any abnormality occurs, immediately stop operation to avoid risk of electric shock, injury, or fire.
- - Even when stopping the motor in an emergency, do not use the servo motor's built-in mechanical brake. Be sure to use a control logic that activates the mechanical brake after deceleration by the dynamic brake. For details, refer to the motor manufacturer's instruction manual.
Inspection Procedure
1. Ensuring safety during maintenance and inspection (using the maintenance bar)
If you are forced to place your body or part of your body under the tabletop frame during maintenance or inspection, be sure to set the maintenance bar.
Failure to take measures to prevent falls may result in serious personal injury, including death. Before starting work, remove all transported objects from the top of the lifter.
When restarting operation, be sure to check that there are no maintenance bars remaining inside the machine.
*Do not modify the maintenance bar under any circumstances. Modifications may lead to serious accidents.
Furthermore, suspending the tabletop frame using a crane or similar provides a double safety measure.
2. Zip Chain Inspection (Every Month)
- (1) Remove the transported item.
- (2) Take measures to prevent the lifting part from falling.
- (3) Check the following points along the entire length of Zip Chain.
- -Check for any oxidized wear debris (reddish brown) coming out from between the plates.
- -is there any oxidized wear debris (reddish brown) on the outer circumference of the chain roller?
in the above cases, grease immediately. - - Check if the chain roller is cracked.
- ・Check the chain rollers for any significant roughness due to wear.
If any of the above occurs, please stop using the product and contact us.
3. Greasing
For details on greasing this product, please refer to the table below.
| Usage category | Greasing method | Recommended oils and fats | Grease Cycle |
|---|---|---|---|
| Zip Chain | 10 to 15 g per 100 mm of stroke Apply with a brush using the following as a guide |
Heavy-duty grease type 1, No. 2 equivalent Shell Gaddus S2 V220 J 2 (EP) * [Shell Lubricants Japan K.K.] |
3 months or Every 100,000 round trips |
| Roller wearstrip | Apply an appropriate amount with a brush | ||
| Roller | Apply an appropriate amount with a grease gun |
*Former name: Shell Albania EP Grease 2
(Zip Chain Greasing)
Follow the steps below to lubricate Zip Chain.
- [1] Remove all items from the top frame.
- [2] Take measures to prevent the lifting unit from falling.
- [3] As shown in the diagram on the right, grease all exposed rollers.
(Greasing of wearstrip and rollers)
Apply grease to the rail running surfaces (both top and bottom).
After greasing, perform a break-in run and remove any excess grease before starting operation.
