Frequently Asked Questions - EHU-3 Vestil

How do I install the EHU-3 hoist?

Installation should be performed by qualified personnel. Ensure the supporting structure can handle the load capacity and dynamic forces. Mount the hoist using appropriate bolts and hardware. Connect power supply matching the voltage rating (230V/460V 3-phase). Refer to the user manual for detailed installation steps.

What voltage does the EHU-3 require?

The EHU-3 operates on 230V or 460V, 3-phase, 60 Hz. Verify the supply voltage matches the hoist's nameplate before connecting.

How do I maintain the chain?

Inspect the chain for wear, stretch, or damage monthly. Lubricate the chain every 40 operating hours using a recommended chain lubricant. Replace the chain if elongation exceeds 2%.

What safety features does the EHU-3 have?

The hoist includes an overload clutch, upper and lower limit switches, and an emergency stop button on the pendant. Always check these features before each use.

What is the lifting capacity?

The EHU-3 has a rated capacity of 3 tons (6,000 lbs). Never exceed this limit to avoid equipment damage and personal injury.

How do I replace the chain?

Chain replacement must be done by trained personnel. Use only Grade 80 load chain of the correct size. Follow the manual's procedure to thread the chain through the sprocket and secure the ends.

What should I do if the hoist stops working?

First, check the power supply and emergency stop button. Ensure the overload clutch hasn't tripped. Inspect the limit switches and control cable. If unresolved, contact Vestil service.

Can the hoist be used outdoors?

The EHU-3 is designed for indoor industrial use. Outdoor operation requires weather protection to prevent moisture damage to electrical components.

3. DAILY INSPECTION

Daily inspection is effective to find the malfunction or fault on the lift table. Before operation, check the lift table according to the following points.

CAUTION! Do not use the lift table if any malfunction or fault is found.

◇ Check all the terms of WARNING and CAUTION.

◇ Check scratches, bending or crack on the lift table.

◇ Check smooth movement of the table.

◇ Check if there is any hydraulic oil leakage.

◇ Check the vertical creep of the table.

◇ Check if all the bolts and nuts are firmly tightened.

4. Operating the lift table

- LOADING

The maximum capacity of the lift table is 2,000/3,000 lbs load should be distributed on the lift table equably.

■ Lifting the Table

CAUTION! Do not overload the lift table. Ensure the balance of loading. Do not load partially or concentrically

◇ Screw and loose emergency stop switch.

◇ Push the UP button and power pack starts to work to lift the load.

◇ Loose the UP button and power pack stops working.

■ Lowering the Table

WARNING! Do not put foot or hand in scissors mechanism.

◇ Push the DOWN button and the table will lower.

◇ Loose the DOWN button and the table will stop.

NOTE

◇ The table is equipped with an aluminum guard to avoid accidental danger.

If aluminum guard strikes an object while the table lowers, stop operation and check the lift table. After making sure no any abnormality, strike the UP button slightly and then the electric system will function as before.

Emergency stop

◇ There are two methods of emergency stop as follows.

◇ Push down the emergency stop switch and the movement of table stops.

◇ Strike aluminum guard upward and the movement of table also stops.

■ Transportation

If necessary, the lift table can be transported with attached ringbolts.

◇ Pay attention to the maximum capacity of lifting equipment to be used.

◇ Keep the ringbolts with reasonableness.
