FAQ for ENDO KOGYO EHW-120R Air Balancer (120kg, 1.9m, 0.6MPa):
1/ What is the ENDO KOGYO EHW-120R and where is it used?
The EHW-120R is an air-powered wire hoist designed to lift, lower, and hold loads up to 120kg with a 1.9m stroke.
It’s widely used in automotive assembly, machinery maintenance, chemical plants, clean rooms, and any production line requiring ergonomic lifting and precise positioning.
2/ What are the air supply requirements?
Maintain a clean, dry, oil-free compressed air supply at 0.5 - 0.6MPa to ensure smooth operation and cylinder longevity.
Recommended minimum airflow is 50 L/min, with piping of at least φ10mm (φ12mm preferred) to minimize pressure drop.
3/ How do I install the EHW-120R?
- Securely hang the balancer from a structural beam or trolley rated at least four times the maximum load.
- Install an air shut-off valve within 1m of the balancer for emergency isolation.
- Route the air supply tubing straight to the inlet, avoiding sharp bends or kinks.
- Tighten all fittings and check gaskets before pressurizing.
4/ What is the basic operating procedure?
- Open the air shut-off valve and confirm system pressure at 0.6MPa.
- Use the pendant pushbutton to raise or lower the load; higher buttons increase speed, lower buttons decrease speed.
- Release all buttons to lock the load in position automatically via the internal locking valve.
- Adjust fine-tuning speed control knob on the pendant for precise positioning.
5/ What routine maintenance is required?
- Daily: Inspect for air leaks at fittings and clean dust off the hoist body.
- Weekly: Lubricate guide rollers and seals with silicone oil.
- Monthly: Disassemble and inspect one-way valve and replace O-rings if showing wear.
- Yearly: Calibrate lifting force and verify lock-valve performance; undergo safety inspection.
6/ What safety features prevent load dropping?
The EHW-120R incorporates an internal locking valve that engages if air pressure falls, ensuring the load descends slowly rather than free-falling.
A reverse-winding prevention device stops the wire from unwinding in the wrong direction and automatically halts the motor when the full 1.9m rope is extended.
7/ What are common issues and how can I troubleshoot them?
Symptom
Possible Cause
Recommended Action
Load won’t lift or moves slowly
Insufficient air pressure or clogged filter
Increase to 0.6MPa, clean or replace air filter
Load descends too quickly
Speed control valve misadjusted or faulty
Adjust knob or replace control valve
Continuous hissing or air leak
Worn O-rings or loose fittings
Replace O-rings, tighten connections
Hoist doesn’t stop at full stroke
Rope-end auto-stop mechanism jammed
Inspect and clean reverse-winding device
