Introduction
This electric hoist ER2 is designed and manufactured for the purpose to lift and lower a load within a normal
work environment. The motorized trolley MR2 and the manual trolley are designed and manufactured for the
purpose to move the lifted load laterally with the combination with the electric hoist.
Movement of a load in a 3D direction such as up/down, forward/backward and right/left is also enabled by
combining with a crane.
This Owner's Manual is intended for those operating the KITO electric hoist ER2 and maintenance engineers
(* pesonnel with expertise).
Other than this manual, Disassembly/Reassembly Manual and Parts List are also available for the maintenance
engineers. Assign the maintenance engineers and use these materials for inspection and repair. Please contact
the nearest distributor or KITO for these materials.

■General Matters on Handling of Dual Speed VFD Model
The dual speed VFD model electric chain hoist is controlled by VFD for important items related to safety such as
operation, braking and emergency stop. Be sure to follow the safety precautions below as well as the above safety
precautions.
•Do not change parameters.
When parameters need to be changed, ask distributor or KITO.
•Do not carry out the work such as maintenance and inspection within 5 minutes after power off.
Wait for the completion of discharging of the capacitor inside the VFD.
•Do not touch the controller cover as it becomes hot during operation.
Do not touch the controller cover until about 30 minutes elapsed after the stop of operation.
•USE KITO genuine VFD.
The VFD requires the special specification for KITO. Be sure to use genuine VFD.
•Do not change the connection of the VFD.
When the wires were removed for any reason, connect them again correctly checking the wiring diagram inside the
controller cover.
•Do not carry out withstand voltage test and insulation resistance measurement of a circuit by megger
while the VFD is connected.
•Do not turn off the power while operating.

•Be sure to check that the Load Chain has "RH-DAT" or "FT-DAT" mark on it and the chain size is
appropriate for the ER2 model you are using. (See the following table.) The Load Chain of other models
(such as model ES or ER) or different rating cannot be used.
Use of the Load Chain of other model or other rating may result in death or serious injury due to the drop of the lifted
load.
Mandatory
The mark (RH-DAT) to indicate the model of the Load
Chain is indicated on it at an equal spacing. Make sure
that the Load Chain is of a chain size (wire diameter)
appropriate for ER2 referring to the table in the left.

ISO 4301 specifies the total operating hour (service life) of gears and bearings according to the loading status. For
example, the total operating hour (service life) of the mechanism when it is constantly applied with the capacity is
1,600 hours for M5. The total operating hour is 6,300 hours when operated with a medium load.
* Rate of loading
Light : A case where the capacity is rarely applied. Usually the hoist is used with a light load.
Medium : A case where the capacity is applied considerably frequently. Usually the hoist is used with a medium
load.
Heavy : A case where the capacity is applied considerably frequently. Usually the hoist is used with a heavy load.
Ultra heavy: A case where the capacity is applied constantly.

CAUTION
ER2 Series Electric Chain Hoist has two models: single speed model and dual speed VFD model. Other than them,
such products are provided that can travel/traverse when combined with a trolley or a crane. Their push button switches
for operation differ in the size and the operating method. Check the product model of the hoist and use it properly.
Prohibited
•Do not use the product with an illegible nameplate or warning label affixed to the body size.
Failure to this instruction may result in the injury or the property damage.
•When using the product for the first time, affix the labels indicating East, West, North and South on the push
button switches.
•Check the contents of the work and make sure that the electric chain hoist has proper performance for the load
and lift.
•Check the contents of the work and operate the electric chain hoist at a place enabling to look out the operating
area without hindrance.
•When looking out the operating area is difficult, arrange the monitor near the place for safety.
•Operate the electric chain hoist at a place with firm foothold without danger of falling, stumbling, slipping or
over turning.
•Before moving the load, warn all the surrounding people.
•Even if the crane or the electric chain hoist is permanently installed and used for the same purpose repeatedly,
check the contents of the work and make sure that the work does not exceed the capacity on each occasion.
•Appoint the maintenance engineer or competent personnel among the qualified personnel for operation of
cranes and electric chain hoists. Indicate the name of the personnel on a place with legibility.
•The maintenance engineers shall check the result of daily inspection.
•When informed of abnormality of the electric chain hoist, the maintenance engineers shall take immediately
any necessary measures such as prohibition of use and repair.
