,QWURGXFWLRQ
This electric hoist EQ is designed and manufactured for the purpose to lift and lower a load within a normal
work environment. The motorized trolley MR2Q 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 EQ and maintenance engineers
(* pesonnel with expertise).
Other than this manual, Disassembly/Reassembly Manual is 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.
* A person who has a thorough knowledge of the structure and rolls concerning Electric chain block and is
recognized as an expert by an entity.

■General Matters on Handling of EQ Series Electric Chain Hoist
The EQ series 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 reassemble the EQ series electric chain hoist to contactor type.
•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 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.
•Never turn off the power when a load is suspended.
Never, under any circumstances, turn off the power when a load is suspended. Doing so will cause the load to be
slightly lowered after the power is turned on again due to control system initial preparation.
Failure to comply with these instructions may result in death or serious injury and the damage of VFD.
Prohibited

How to UseDaily Inspection of Electric Chain Hoist (EQ Type)
How to Use
•Do not use the Hook without a Hook Latch or damaged Hook.
•Do not use the Load Chain with heavy elongation, abrasion or deformation.
•Do not cut, extend, or weld the Load Chain.
•Do not use the Load Chain with the Bottom Hook without smooth motion.
•Do not use the Load Chain when its brake does not function securely even without load, or when the stopping
distance is too long.
•Do not use the product if it moves oppositely to the direction indicated on the push button switch.
Failure to comply with these instructions may result in death or serious injury.
•Carry out daily inspection before operation.
(When any abnormality was found during inspection, turn off the power, indicate “FAILURE" and ask the maintenance
engineer for repair.)
•Check the slinging devices for no abnormality.
•The diameter of the Suspension Shaft hooked by Suspension Eye should be thinner than 31mm or less.
Failure to comply with these instructions may result in death or serious injury.
Mandatory
CAUTION
KITO Model EQ Electric Chain Hoist is a 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.
•When carrying out inspection and repair, secure the environment for safe work without electric shock and falling.
Failure to comply with these instructions may result in bodily injury or property damage.
