Features of the DA/DB Electric Chain Hoist
An efficient motor that offers high lift speeds
The DA/DB series hoist features a newly developed motor for severe
conditions, which allows it to operate continuously for long periods of
time with frequent starts within an hour cycle. These lifting speeds
were engineered to be as fast as possible to ensure efficiency.
Quiet operation with a sealed protective body against dust
Durable helical gears & an oil bath style gear case make these units
quiet during operation.
Solid steel side plates for a rugged heavy duty construction
Highly durable load chain
Our surface hardened load chain is manufactured within our factory in
Osaka, Japan and is in compliance with ISO standard grade T, offering a satisfactory degree of breaking strength, wear resistance, and
impact absorption. We can also offer load chain of a higher corrosion
resistance upon request.
Safe DOUBLE BRAKE design
A mechanical brake and motor brake – the electric-magnetic brake is
combined with a mechanical brake to constitute a complete double
brake system. Even the former alone has enough capacity to hold a
static safe working load!
DC brake and motor with low power consumption
Please read operation manual
in the box before setting-up,
installation, and operation.

A DC solenoid is used for the electro-magnetic brake. This lowers
the electrical consumption throughout the operation of the electric
chain hoist.
A safer chain guide with our unique design
The DA/DB series is designed so that the chain guide’s rotation on the
load sheave transmits to the electrical limit switch. The electric limit
switch automatically stops the operation of the hoist in the event that
the load chain is raised or lowered to the chain’s end. In this case,
the limit switch would also engage if dust or foreign matters remain
pressed within the pockets of the load sheave.
Reliable double-action limit switch
Electrical limit switch for this model acts in two steps. In the first step
the limit switch breaks the operating circuit. Then within the second
step, the limit switch breaks the main circuit. Ensuring the hoist ceases
operation.
Negative phase contactor and a highly efficient magnetic
contact with a mechanical & electrical interlock
Motor frame
The motor frame is constructed with high quality aluminum cooling fins
which help reduce the rise of temperature within the motor
Durable chain container
Pendant control switch is set at 24v for safe operation
Push-push button style pendant for the DB models
Top and bottom hooks with safety latch
Designed to gradually open and not break suddenly in the event of an
overload. A compact thrust bearing also helps to prevent the load chain
from twisting.

蘆For understanding the descriptions at the upper row of the Table:
trolley's top B/4
1. As for the rails belonging to the blue indicated zone, the standard type trolleys can be fitted to each of them.
2. As for the rails belonging to the gray-indicated zone, such trolleys as having special dimensions to meet them
(a)
must be prepared separately.
(c)
蘆For understanding the descriptions at the medium row of the Table:
(b)
Each of the figures indicated at this row shows the distance [a](unit:mm) of the sketch at right side.
This distance [a] may be zero or negative depending on the combination of the standard trolley with some types of
rails: for this case, no figure is given here because such combination can't be put in actual application.
In the case of the combination indicated with a blue figure, the trolley's top is higher than the rali's top so that the torlley may touch the ceiling
suspending the rail (H≦K):pay attention to this.
蘆For understanding the descriptions at the lower row of the Table:
Each of the figures indicated at this row shows the distance [b](unit:mm) of the sketch at the right side. The distance [b] may be zero or negative
depending on the combination of the standard trolley with some type of rails: for this case, no figure is given here because such combination can't
be put in actual application. Also for the rails whose thickness t2 is too thin to hold the rated load, no figure is given.
If there is even one blank at either of the upper, medium and lower rows of the Table, this means that such relevant rail can't be used to together
with the trolleys.
In this way, referring to the Table, you will see what type of rail(I beam) is suited to the trolley you have selected.
Then it is needed to check if such rail satisfies the following condition: even if it is given a 125% of the rated safety load, its deflection amount shall
be 1/1200 of its support span or less. That is, the I beam to be selected shall have its moment of inertia of the longitudinal section (lx) be as follows:
lx: Moment of inertia of the longitudinal
logitudinal section ≧ 119.1×W×L2
In which,
W: W.L.L.×1.25+Chain block's own weight(ton)
L: Support span(m)

For "Combination of Electric Trolleys with Traversing Rails", the following must be taken note of:
At the medium row of the table:
In the
case of thefrom
combination
※continued
page 11indicated with a gray zone, the relation H≦K applies to both plain trolley and geared trolley.
In the case of the combination indicated with a blue zone, the relation H≦K applies only to the geared trolley.
For "Combination of Electric Trolleys with Traversing Rails", the following must be taken note of:
At the medium row of the table:
＊The dimensions A, B, C of the trolley will vary with the change of the traversing rail's width to be used.
In the case of the combination indicated with a gray zone, the relation H≦K applies to both plain trolley and geared trolley.
The figure β in the Table can be obtained from the following equation: β=1/2x[width(mm) of the traversing rail-γ]
In the case of the combination indicated with a blue zone, the relation H≦K applies only to the geared trolley.
＊The dimensions A, B, C of the trolley will vary with the change of the traversing rail's width to be used.
The figure β in the Table can be obtained from the following equation: β=1/2x[width(mm) of the traversing rail-γ]

Class Code
Typical Examples
To show the number of falls
To show the rated load
capactiy(ton)
To show the class of each
model
蘆Class code:
It identifies the type (single speed or dual
speed type), the number of buttons on the
control switches and kinds of trolleys
(electric, geared or plain). See the sketches
at right.
蘆Rated load capacity:
It shows the rated load capacity(ton) of the
relevant chain block.
蘆Number of falls:
It Identifies whether the relevant chain
block is the 1-fall type or the 2-fall type
block(S=1, W=2).
Note: Indication of the number of falls is
omitted for certain model in the case
where it has been specified
according to its rated load capactiy.
Usually the pushbuttons located on the control switch are labeled as "UP", "DN", "L", "R", "E", "W", "S"
and "N". The other types of labeling are avaliable upon request.
In the case of the dual speed type (DB type), the chain block can be wound UP and DOWN at either high
speed or low speed. The UP
and Down buttons are each of push-push type: at the first push, it
provided low speed operation and at the second push, it provides high speed operation.
