Operation
EKZT-Series | Version 1.04 11
7.1 Operating conditions
The working area must be dry, fire and explosion pro-
tected and free of any corrosive or poisonous sub-
stances.
The chain hoist. must not be used to lift or move danger-ous
goods such as molten, poisonous or radioactive materials.
The electric chain hoist is not intended for outdoor use. If
outdoor use is required, appropriate roofing of the
electric chain hoist must be provided.
Operating time: 2m/M5 40%
Working cycle 10 minutes, including 4 minutes of opera
-
tion and 6 minutes of rest.
7.2 Electrical connection
Step 1: Check if the mains voltage complies with the
tension indicated on the type plate..
Step 2: Connect the mains cable to the power supply
system.
Step 3: Press the control bar button and check the
function of the electric chain hoist.
Step 4: If the chain hoist fails to move (phase sequence
safety device has been activated), switch off
the safety device and correct the phase se
-
quence.
7.3 Test run
Before using the chain hoist to lift a load, a no-load test
should be carried out to test all functions. In particular,
the function of the raising and lowering limits should be
tested.
7.4 Raising a load
Step 1: Hit the hook of the chain hoist on a suitable an
-
chorage point of the load and check that the
safety of the hook is closed.
Step 2: Press the button "OPEN" and initially drive only
until the load chain is tensioned.
Step 3: First, lift the load only a short distance and
check that the chain and load are stable.
Step 4: Lift the load calmly and evenly upwards.

DANGER!
Danger to life due to electric cur
-
rent!
There is an imminent danger of life in case of con-
tact with life components by electrocution.
- The chain hoist must only be connected by a quali-
fied electrician.
- Work on the electrical system may only be carried
out by qualified electricians.
ATTENTION!
Devices with 400 V / 3-phase connection have a
phase sequence protection device: If the phase
sequence is incorrect, the power supply is automati
-
cally interrupted.
NOTE!
- Do not wind load chain around load.
- Load chain must not be turned in itself.
- Check the center of gravity of the attachment point
to prevent movement and slippage of the load.
- Slings (eyelet, chain, etc.) must lie loosely in the
hook base.
- Hook tip may not be loaded.
- Close the fuse.
NOTE!
- The operator must have sufficient freedom of move
-
ment.
- The chain hoist must be able to swing freely in the
pulling direction.
- Lift and lower limit: When the lift limit is reached, the
power automatically shuts off and the load hook
stops immediately.
- The load hook deforms when overloaded, there is
no brittle breakage.
