Is it possible to use Spring balancer with lied position? |
|
|
- Possible.
Note 1) Take load with the upper hook
Note 2) when using a roller, be careful for position of Spring balancer so that wire rope should not be twisted.
|
| |
|
Is it possible to use Spring balancer outdoors? |
|
|
- Apply a rain-cover because Spring balancer is indoor use. Let us know if Spring balancer is used in severe location.
|
| |
|
What’s the difference between Spring balancer and Torque reel? |
|
|
- Spring balancer keeps the balance of load by taper drum.
Workers can enjoy comfortable operation with less fatigue.
|
- Torque reel has no balance because of cylindrical drum.
The stroke (3～4m) can be held in the middle of the stroke by ratchet mechanism (ER -3A, 5A, 10A ).
Main application is suspending a pendant switch.
|
| |
|
Which model is better, small or large, when capacity overlaps to two models? |
|
|
- Larger capacity model has longer spring life.
|
| |
|
Is it possible to exchange the spring? |
|
|
- The spring is cartridge type and can be exchanged safely.
Note) Some models are inapplicable.
|
|
Is it possible the wire rope to be locked in the middle of stroke? |
|
|
- The model, which has drum lock or ratchet system, can lock the wire rope.e.
|
| |
|
What’s the difference between EW (old model) and EWF (new model)? |
|
|
- The case of EWF is full-covered, and it is safe design without catching fingers.
|
- It is economic design that the exchangeable wire guide makes life of the case and wire rope longer.
|
- It is the kind design that enables tension adjustment from floor. Because the warm of spring adjustment is faced downward.
|
| |
|
What’s the difference between EWF and ELB? |
|
|
- The stroke is different. ELB is long stroke model (2.5m).
|
| |
|
What’s the difference between ERP-1 and ERP-1E? |
|
|
- The material of rope is different. ERP-1 is carbon steel and ERP-1E is nylon fiber.
The ERP-E series has been in your market since April 2006. ERP-series is discontinued.
|
| |
|
Is it possible to extend the stroke of Spring balancer? |
|
|
- Basically impossible. Only the length of wire rope can be extended, but the drum
cannot wind the extended length. In addition, new model will be produced depends on
your demand (number of lot, stroke, capacity). Please contact us if you have any special demands.
|
| |
|
Is it possible for Spring balancer to convey the load? |
|
|
- Possible with trolley, but it is dangerous to detach the load from the lower hook.. In this case, Air hoist is more suitable.
|
| |
|
What is the fall arrest device? |
|
|
- It is tool fall protection when spring breakage.
Note) Some models, especially light capacity have no the fall arrest device.
|
| |
|
Is it easy to pull the stroke of RSB without the load? |
|
|
- It is not easy because of spring tension against pulling.
A ratchet of RSB can be locked only for winding direction. Therefore, hang the load and keep operation.
|
| |
|
Is it possible to use some Spring balancers in one application? |
|
|
- When installing them in parallel, the stroke and setting capacity must be same.
|
| |
|
Is it possible to install spring balancer with roller to application? |
|
|
- Dimensions and shape of the roller connected with wire rope is import.Be careful for position of Spring balancer so that wire rope should not be twisted.
|
| |
|
|
- Spring balancer keeps the balance of load by taper drum.
Workers can enjoy comfortable operation with less fatigue. Main application is suspending tools.
|
| |
|
How long is the spring life? |
|
|
- It is different depends on model or stroke. Please contact to the distributor.
|
| |
|
Is it possible to suspend the load over capacity? |
|
|
- Setting over capacity causes early breakage of spring or not enough stroke.
The fall arrest device functions when setting capacity less than the minimum
Never set capacity over maximum or less than minimum.
|
| |
|
Is SUS wire rope available? |
|
|
|
| |
|
Is SUS lower hook available? |
|
|
|
| |
|
How much is permissible over capacity? |
|
|
- Setting over capacity causes early breakage of spring or not enough stroke.
The fall arrest device is functioned when setting capacity less than the minimum.
Never set capacity over maximum or less than minimum.
