• ASIAN New AATF, SWA, SBH Series & I-Beam Trolley
Spring Balancers / Tool Balancers are specially designed to free the operator from the weight of hand tools. The tool balancers can be pulled down with least pressure, without any strain or fatigue. Handling of the tool balancers is very easy as the load balancers and pressure required for operation is counter balanced in the mechanism of Spring Balancers / Tool Balancers itself. The operation is free of gravitational force.

• Rugged Construction
Main housing and cover plate are manufactured from high tensile lightweight Aluminum Alloy for maximum resistance against impact and ease of handling. Upper support hook assembly and Bottom suspension hook assemblies are manufactured of forged steel to provide maximum safety. Standard flexible wire rope is used for cables to provide good flexibility and fall safety.

• Tapered Cable Drum
Unique cable drum design matches the middle turns of Spring Balancers / Tool Balancers, where the optimum torque build-up is constant. This design feature provides smooth, and even cable tensions throughout the entire length of cable travel.

• External Tension Adjustment
External tension adjustment is easily accessible from the floor. Tension can be set at the exact requirement through a hardened worm form gear system. No special tool needed.

• Swivel on Top Hook
Allows 360º rotation. Positions the Spring Balancers / Tool Balancers for easiest cable flow. Prolongs cable life.

• Automatic Drum Lock
If Spring Balancers / Tool Balancers tension declines sharply, an automatic locking mechanism immediately engages, preventing the load from falling.

• Manual Drum Lock
Suspended tools can be changed easily by engaging the manual drum lock. After tool balancers or cable has been replaced - WITH FULL LOAD ATTACHED, manual drum lock can be released - DO NOT RELEASE MANUAL DRUM LOCK WITHOUT ATTACHING FULL LOAD. This can be done on the job site in minutes, without removing tension on the Spring Balancers / Tool Balancers cable. This convenience makes change over safe, simple and quick, reducing costly down time.

"ECO" Spring Balancer
The Series "ECO" Spring Balancers are the "eco-friendly" balancers. They are the ultimate solution when particulates from the standard exterior balancer finish might contaminate food or sensitive assemblies. 

The specific features of the "X" version are:
• Buffed and barrel-polished casing and cover
• Synthetic food-grade grease (H1 grade) on the spring
• Stainless steel lower hook, plug, rivet, bolts, and screws
• Zinc plated upper hook and pins

  Rope Types:
• EW-3 to EWS-7: White Nylon, 3 mm diameter.
• EWF-9 to EWF-15: Black Nylon, 4 mm diameter
• EWF-22 to EWF-120: Stainless Steel, 4.8 mm diameter

  The Series EW-Y, EWS-Y, and EWF-Y tool balancers are also "eco-friendly" balancers. These are ideal when particulates from the standard exterior finish might get into food or sensitive assemblies and where a buffed/polished housing and food-grade grease are not required.

The specific features of the "'Y" version:
• Unpainted casing and cover (not buffed)
• Standard grease on the spring
• Zinc plated steel lower hook, plug, rivet, bolts, and screws
• Clear painted rivet
• Zinc plated upper hook and pins

Despite being compact and lightweight, this reel provides a long stroke of up to 4m (winding length). Due to the use of a cylindrical drum, the tension (winding force) increases gradually as the wire rope is pulled out. The cylindrical drum also prevents cable jamming even when you pull out the wire rope in an oblique direction. Balance is obtained at the preset height and the wire rope is wound up after being pulled out again. The models with the ratchet mechanism (ER-3A, 5A, 10A) can be stopped even during strokes.

Model	Maximum initial tension (Winding tension) N[kg.]	Winding length (m)	Additional tension (caused by pulling out the wire rope) N[kg.]	Effective number of spring turns	Ratchet	Wire rope diameter (Mm)	Mass (kg)

AAT-10B	49[5.0]	4.0	49[5.0]	Approx.13	-	2.38	3.8

Clean Room Balancer
With its enclosed casing, this balancer prevents dust from scattering and therefore can be used in a clean room.
The casing is conductive but grounding can be achieved using an earthing wire.
The bracket enables easy installation. (Installation diameter Φ32 mm)

• 1.Confirmation Product of Contents
  
  

  • 1.Spring Balancer (1 Unit)
  • 2.Support site guide (1 copy)


• 2.Confirmation of Model
  Check the model type on the nameplate

  After confirming the model, be sure to download and read the instruction manual before installation.

• 3.Installation and safety measures
  

  Lift up the main unit and hang it over the closed support member. An auxiliary chain or wire should be attached to the auxiliary hanger of the balancer body to prevent the balancer from falling if the upper hook or its connection parts fails. The auxiliary chain or wire should have some leeway to allow the balancer to move freely. Refer to the instruction manual of the range of necessary leeway.

• 4.Factory tension setting
  

  When shipped, the spring tension of the balancer body is adjusted to the center of the setting load gauge. In the image, EWF-22, 15kg to 22kg Center of the load gauge=18kg

• 5.Check the weight of the load
  Check the weight of the suspended load before it is applied to the balancer. If the weight is known, it is not necessary.
• 6.Tension Adjustment
  

  Before suspending a load, adjust the spring tension according to the weight of the load.
  There are “handle type”, “ratchet type” and “worm type”.
  For all ENDO balancers, turning the adjustment parts clockwise increases the spring tension, and turning counterclockwise decreases the spring tension. Adjust the spring tension so that the gauge scale for the suspended load is set to the capacity indication point.
  ※The lightweight model does not have a gauge, so please adjust it after suspending the load.

• 7.Hang a Work piece
  

  Lift the load and hang it in the bottom hook.
  If the hook is released from your hand before the load is attached it will retract quickly potentially causing injury or damage to the balancer and or load.

• 8.Complete Installation
  

  The load value indicated by the gauge scale is for reference only. Make the final spring tension adjustment while checking the balancer point of the suspended work piece. The installation is now completed.

TROUBLESHOOTING

Caution 1
Malfunction due to activation of safety devices.

• Do not set the tension gauge below minimum set load (15kg).
• Doing so will result in the safety device being activated and the wire rope will not be able to be pulled out.
• ※In the image, the minimum set load has been set below 15kg.
• This condition can be deactivated by increasing the spring tension.

When deactivating the safety device, make sure the work load is still in place on the bottom hook to prevent the wire rope from rapidly retracting potentially causing injury and/or damaging the equipment. Make sure the work piece weight is within the tension gauge.

Caution 2
Malfunction due to tightened winding of the spring

• If the spring tension is increased beyond the maximum set load, the wire rope cannot be pulled out.
• Do not set the spring tension beyond the maximum setting on the gauge.
• ※In the image, the maximum load setting is set over 22kg.
• The wire rope can be pulled out by reducing the spring tension.

When deactivating the safety device, make sure the work load is still in place on the bottom hook to prevent the wire rope from rapidly retracting potentially causing injury and/or damaging the equipment. Make sure the work piece weight is within the tension gauge.
