Ⅰ. Operator's Instruction
LT, LD Type symbol classified by machine
* Please conform product's type number which you us
"S" or "W" is for number of Chain. S = Single chain, W = Double Chain

Chapter.1. Noteworthy for installing an electric chain hoist
1.Checkup before installing
● There are several check points as follow;
1) Model 2) Voltage (3 phase, Voltage 220V, 380V, 440V. 460V)
3) Proof load 4) Trolley type 5) Lift
6) Push button type 7) Power cable length
8) Operating instruction 9) Any damage during moving and loading
2. Check point for particular cases
* Do no exposure to explosive places (explosion disposal hoists are available)
* Do not use or make an inquiry to the service center in a particular situation as
follows;
Under high temperature (over 40°C), Under low temperature (under -15°C),
in high humidity (over 85%), in the high elevated areas (over2000m)
In a basin(IP54)
* Especially to use in a low temperature, need to have extra capacities against
breakdown.
* lighting fixtures - keep 150LUX at the least from the driver's sit against any
accidents caused by mishandling.
* It produce around 71dB. For the quiet order, make inquiries at an office
* Control voltage...
3. Power
* Hold a power sauce failure or power transmission failure against a fire.
* Keep the Instruction for setup.
* Check the voltage and so on
4. Working rate
* Load time rate
* Safety index
5. Safety supervision
* Have safety wears such as gloves, boots, a crash helmet keep free from the
danger
6. Checking HOIST SPARE PART
1)CHAIN GAUGE (see the page 24 ,
2)OIL funnel (see the page27
LT,LD-TYPE HOIST is designed to stop operating hoist by the CLUTCH SLIP
action for avoid over loading. Therefore, when you use LT ,LD type of hoist,
need to observe the proof load.

7. All the parts of body & every cases
*from the unpacking to setting up
(1) LOAD CHAIN
*Check out if the load chain in the pack is
tied to wire ; which is to avoid mixed-up.
Remove every pieces of wire, vinyl, tags
and so on from the chain so that the hoist
body can be free from the dust.
* Do not use a load chain before remove
every twist or knot
(See the picture1)
* Remove all the dust before setting up or
operating the hoist
* When you operate more than double load
chain, the low class chain can
possibly slip out between the chains to make
a twist. Do not operate it with the twist
still on. It is dangerous.
Let the low class hook to be get out in
opposite way. (see the picture no.3)
(2) Chain back install
* It is necessary to install a chain bag. If
you don't install a chain bag, unloaded
part would be stuck.
* After the unloaded part comes out about
50m, install the chain bag, It is a lot
easier also the load chain can fit in the
chain back appropriately.

Plastic No. 8 40M 20M 18M
* Let the chain back hang down from the
electric chain hoist naturally. As the chain
bag is packed, load chain would be pushed
to be stuck in the chain hoist.
It can make trouble and danger.
Also it is dangerous if the chain bag is
much longer than the load chain. If you
change the load chain into longer one, the
chain bag should be the appropriately long
enough..
(3) Torque Limiter (Sleep Clutch)
*Do not set the torque Limiter on power for
nothing . Torque Limiter is only for
emergency. No matter it has regular
durability, clutch part would be worn out and
unable for the proof load. As you need to
operate low and upper Limit Switch, b u y
a LD-TYPE HOIST to set up. (option)

(4) Body throbbing
Chain hoist body is hang down from the hook or
the trolley in natural to use. As the polygon shaped
LOAD SHEAVE ,which delivers power to a load
chain, spins to , it brings some throbbing.
Do not let the body collide with or drive the chain
hoist without HOOK.
It is very dangerous because the repressed energy
spreads all over the essential parts. (see the
picture7) The body should be hand down in natural
(6) Keep the rain away
Do no expose electric chain hoist to the rain. It
extremely shortens the durability.
As you set it outdoors, find shelter in a safe from
a rain. The chain should be free form the rain.
8. Notice : Trolley adhered cases
(1) ADJUST COLLAR
*As you convert the adjust collars, trolley is
available to be organized with various rank-rail.
(width 12.5mm). There should be the same number
of collars in the both sides of the connector. Do
not install like picture no10. It cause the accident.
(2) Installing in a rounded horizontal rail.
As you install a electric trolley or gear-trolley in a
rounded horizontal rail, WHEEL, or the
hand-powered wheel should be set to the external
from the curve.
Do not set a motor or a hand-powered chain
inside, The rank-rail and the wheel gear of the
trolley will be worn away to cause accident. Take
the shorter turning radius for the standard. (see the
picture no.11)
- 9 -
(3) No partial loading
No matter there is a guide against the overturning,
it is better to avoid partial loading.
(4) Rank-rail.
◆Do not put painting to the trolley wheel, which
directly connect with the rank-rail.
◆Connecting a rank-rail
1. Rank-rail should be connected around the
up-holding of the rail.
2. When you weld strengthen plate under the rail,
take heed of the thickness of it.
Too much thick plates disturb operating. (see
the picture no 13)
3. Do not exceed the limit of the across for up
and down ward , right and left.
Finish with the grinder for the rail part where
the wheel passes by.
◆Stopper at the end of the rail.
1.Attach a stopper at the spacious spot 'a'.
Therefore, you can avoid the hoist
crashing to breakdown. (minimum 'a'=500mm)
2. Stopper should be attached with a shock
absorber to stand up to the impact. (see the
picture no 16) A misplaced absorber causes trolley
to crash.
3. LIMIT SWITCH TOUCH BAR shuts out
electricity before the trolley get crash to a
stopper so that you can keep off an impact.
- 10 -
4. You can avoid any impact by installing the Stopper and Limit switch
for
operation. (Crain only)
5. Additional signal.
Mark on the bottom to avoid operate
failure and damage.
