Determine cable diameter by checking weight of the hanging limits.
Please follow suggested load limits and appropriate cable selection.
| cable diameter selection guide ※1 | tension load test result ※2 | ||
|---|---|---|---|
| cable diameter(mm) | nominal load(kg) | maximum load(kgf) | displacement(mm) |
| 0.6φ | 3 | 16.5～16.8 | ――――― |
| 0.8φ | 5 | 30.2～34.5 | ――――― |
| 1.0φ | 8 | 47.6～50.0 | 6～7(40kgf) |
| 1.2φ | 10 | 56.2～73.4 | ――――― |
| 1.5φ | 30 | 84.8～95.7 | 10～11(40kgf) |
| 2.0φ | 50 | 143.0～146.4 | 17(40kgf) |
| 2.5φ | 70 | 228.0～242.0 | 9～13(40kgf) |
| 3.0φ | 100 | 310～330 | 5～8(40kgf) |
※1 The load limits have been set at 1/3 of the static withstand load. There may be circumstances where a 1/5 safety factor needs to be considered.
※2 The test results are from the Tokyo Industrial Technology Center. Displacement is the value measured at a distance of 110mm between hardware.
※3 Suggested safety weight for hanging with multiple cables [Hanging with 2-4 cables], which are 60% of total each safety weight. Permission load in case of hanging with 5 cables and over, please make sure correspond to hanging with 4 cables. If you have any question in detail, please talk to our company.
Hanging with 1 cable (1.5mmφ)
30 kg × 1 = 30 kg
Total weight never over suggested safety weight (30 kg) at hanging multiple things. In the case of a piece of hanging with 1 cable, you can just apply the permission load.
When you increase in number of hanging works, because of the weight concentrate on metal fittings of a ceiling side, so please adjust it so that total load do not exceeded 30 kg.
Hanging with 2 cables (1.5mmφ)
30 kg ×2×0.6=36 kg
Total weight never over suggested safety weight (36 kg) at hanging multiple things. You can not use that 30kg × 2 = 60kg. Please make sure 60 % coefficient of sake to use safely.
When you increase in number of hanging works, because of the weight concentrate on metal fittings of a ceiling side, so please adjust it so that total load do not exceeded 36 kg.
Hanging with 4 cables (1.5mmφ)
30 kg × 4 × 0.6 = 72 kg
Total weight never over suggested safety weight (72 kg) at hanging multiple things. You can not use that 30 kg × 4 = 120 kg. Please make sure 60 % coefficient of sake to use safely.
When you increase in number of hanging works, because of the weight concentrate on metal fittings of a ceiling side, so please adjust it so that total load do not exceeded 72 kg.
- If cable is to be used repeatedly, it may be damaged over time. Check before use to ensure the cable is not damaged. [drawing #1]
- Ensure the cable will not come in contact with materials other than Grippers, such as shelves, wall or pipes. This may damage the cable. [drawing #1]
- Use stainless steel. [7 × 7 SUS304] Standard steel cable. Standard steel cable may rust, which will weaken the cable.
- When cutting cable, please make sure to solder the cable end.
- Ensure the cable is inserted completely in to the gripper. [drawing #2]
- Do not intentionally apply pressure when a cable is tensioned.[tension gripper for balustrade]
- One cable may get unexpected load more than safety limit due to swing and unbalance of load. Please select the gripper which has enough capacity of safety weight. [drawing #3]
- Refer to "display application" in our catalog. If you have further questions, please contact us.
- When fastening the grippers to floor, ceiling, and wall make sure to fasten tightly and be sure to select the most appropriate type of anchors.
- Ensure the gripper is properly installed. [drawing #4]
- Make sure that the direction of the cable and the grippers will be in a straight line. Otherwise, please use "universal type", if you make angle on the cable. [drawing #5]
- When using the grippers designed to attach to the cables already mounted from floor to ceiling [FMG-1,FMB-1, etc.], make sure they are firmly attached to the cables before use. [drawing #6]
- When using "-S" type grippers, make sure to tighten the safety cap [S] after final adjustment of their position.
- Dust and debris may clog the mechanism of the gripper. If this occurs, replace it with a new one.
- When you use the grippers such as AM-23, BS-23, SF-23, MF-23 to stretch cables on the floor, make the cables hare appropriate tension adjusting by hand. Over tension causes severance of cables and destroy of screw and anchor.
