FAQs

The Chain

What is the load chain made of?

It's made of KITO's original special alloy steel.

Is it possible to make a stainless load chain for an electric chain hoist?

Since insufficient surface hardness and strength render stainless materials unusable for load chains, we consider them inappropriate for electric chain hoists and do not use them.

Increase in Lifting Height

Is it possible to increase the lifting height of the electric chain hoist/chain hoist?
Can the lifting height also be configured for other non-standard lengths?
Also, is it possible to extend the chain after buying one configured to the standard lifting height?

Although the lifting height can be increased, the load chain is heat-treated, which means the chain cannot be extended. Instead, replace the chain with a load chain long enough to meet your needs (hand chains for chain hoists can also be added via a connection link).
Also, for products with chain buckets, the chain bucket may have to be changed depending on the lifting height. In that case, please consult with KITO and KITO's global partners.

When increasing the lifting height of the electric chain hoist, is a different chain bucket needed?

Chain buckets are available in a range of sizes based on capacity/lifting height. Depending on the increase in lifting height, a large-sized bucket may be needed. Please refer to either table of standard bucket lifting heights by models such as ER2, EQ, or EF to determine the maximum lifting height of each standard bucket size.

Is it possible to increase the lifting height of the electric chain hoist/cylinder?

The cylinder type (ER2 and EDC) is designed for operators to operate by gripping the grip, while the lifting height is set to 1.8m to keep it within operators' reach. If you require a special lifting height, please consult with KITO and KITO's global partners.

What is the maximum lift length for Air hoists?

20 m is the maximum lift length for all of the model. Especially for pendant model, the longer the pendant hose is, the bigger the timelag will be on the operation.

Safety

Will any problem affect the electric chain hoist if power fails while it is in use?

The KITO electric chain hoist is designed to automatically apply a brake when the current flow is interrupted to stop the operation. In the unlikely event of a power outage, it promptly stops operation and suspends the hanging load as if the push button had not been activated.

How much excess load can the electric chain hoist (rope hoist) withstand?

The use of any products with excessing rated loads is prohibited. Always ensure use within the working load limit range.

Products: All products

I would like to use the upper limit switch of the electric chain hoist ER2 for positioning.

As described in the owner's manual, the upper limit switch installed is the final device preventing overwinding in emergencies. Please refrain from using it on a regular basis, since this may damage the main body or break the chain. A limit switch for positioning is available as an option - please contact KITO and KITO's global partners separately in this case.

Is it possible to combine the MR2 motorized trolley with the EQ electric chain hoist?

You cannot use the MR2 motorized trolley with the EQ electric chain hoist due to the differences in the electrical specifications. The MR2 motorized trolley is designed and manufactured on the assumption that it will be used in combination with the ER2 electric chain hoist. When combining the MR2 motorized trolley with ER2 electric chain hoist, failure to comply with this instruction may cause the hoist and trolley to malfunction. Concerning the handling of the MR2, see the ER2 electric chain hoist Owner's Manual that is supplied together with the ER2 electric chain hoist. Customer who have bought the MR2 motorized trolley as a single item and require a copy of the ER2 electric chain hoist Owner's Manual should contact KITO and KITO's global partners.

Is it possible to purchase wire rope as a spare part?

We can supply wire rope as a spare part. Since we use an exclusive wire rope for RY hoist, please contact KITO and KITO's global partners when you need wire rope.

I heard that once the JIS eye bolts are used, they cannot be reused for a different work object. Is the Lifting Point available in such a case?

If no abnormality is found in pre-inspection, the Lifting Point can be used several times without replacing the bolts.
The same applies when using it after changing the work object to be attached.

 

Products: Lifting Point

Using the Lifting Point with long bolt, is it possible to tighten a holed steel sheet, etc. with a nut?

It is prohibited to use for tightening with the nut because the working load is considerably reduced.

 

Products: Lifting Point

 

When attaching the Lifting Point to a metal mold, etc., is it all right to insert a spacer, etc. between the shackle and the load in order to prevent their mutual contact?

It is assumed that both the eye bolt and the Lifting Point are attached tight to the work object when used.
It is prohibited to insert an inclusion such as a spacer because the working load is considerably reduced.

 

Products: Lifting Point

 

Please let me know the safety factor of the Lifting Point.

In the case of side lifting, even the model with the lowest safety factor satisfies 5-time.
The factor is higher in the case of vertical lifting.

Operation

How do you change the speed of the electric chain hoist with dual-speed push button operation?

Since a two-stage push-to-switch push button is used, switching from low to high speed depends on the extent to which the push button is pushed. Push to the first stage for low speed and push right in to the second stage for high speed.

Operating Environment

Please explain the usable ambient temperature for the manual chain hoist/electric chain hoist/lever hoist.

Please use the manual chain hoist and lever hoist within the temperature range of -40 to +60℃.
For electric chain hoists, the temperature range for use is -20 to +40℃.

Can the electric chain hoist be installed outdoors?

Yes, this is possible. The equipment is basically designed for indoor use. Therefore when installing the electric chain hoist outdoors or to the place where the hoist is exposed to direct rain, wind and snow, shade the hoist with roof to protect it from rain, wind and snow.

Are any items specified for use as part of countermeasures when using in an environment such as outdoors/quay, etc.?

Various countermeasures are available such as anti-corrosion coatings, etc. according to the operating environment, so please consult with KITO and KITO's global partners.

Why is the lifting and lowering speed different for Air hoists?

Based on the structure of Air hoists, the lowering speed would be faster than lifting speed, since rotative force and the acceleration of drop of the load would be added during lowering operation.
