FEATURES OF DA/DB TYPE①High speed and highly efficient lifting motor

To meet any severe conditions of operating the chain block, DA/DB model employs the newly-developed lifting motor which allows it to operate continuously for a long period and with the frequent starts/hour duties. Its lifting speed is made as high as possible to ensure the enchanced working efficiency.

②Noiseless and dust protective bodyDurable helical gears & oil bath type gear case make quiet operation.

③Solid steel side plate④Highly durable load chain

The load chain is the surface-hardened one whose properties completely agree with the ISO standard Grade T, offering the satisfactory degrees of breaking strength, wear resistance and impact absorption. Chains of high corrosion resistance for special uses are available upon request.

⑤Mechanical brake and motor brake-safe double brakeThe electric-magnetic brake is combined together with the mechanical brake to constitute a complete double brake system, and even the former alone has enough capacity to hold a static safe working load.

⑥DC brake and motor with low power consumptionD.C. solenoid is used for the electro-magnetic brake, and this promises lower electrical consumption throughout the operation of the electric chain block.

⑦Unique chain guide Since this new chain block is designed in such a way that the chain guide rotation on the load sheave is transmitted to the electrical limit switch, operation stops automatically by the function of the limit switch, not only when the chain is wound up or down to its end, but also in situations like as the dust and foreign matters remain pressed and kept in the pockets of load sheave.

⑧Reliable double-action electrical limit switchElectrical limit switch for this model acts with two steps.At the first step, the limit switch breaks the operating circuit, and at the following step, it breaks the main power circuit.

⑨Negative phase contactor and highly efficient magnetic contactor with mechanical & electrical interlock

⑩Motor frameCooling fin of aluminum motor frame can reduce the rise of temperature.

⑪High durability Chain bucket⑫Control switch voltage set at 24V⑬Push-push type push button switch (DB type)⑭Top hook and bottom hook with safety latch

While overload situation, hooks open gradually and not break suddenly.Further compact thrust bearing prevent twisting of load chain.

ELEPHANT ELECTRIC CHAIN BLOCK DA/DB TYPE ISDESIGNED BY UNIQUE IDEA AND TRUSTABLE TECHNIQUE.THIS TYPE IS USEFUL FOR VARIOUS OPERATIONS OF HEAVY LOAD.

蘆For understanding the descriptions at the upper row of the Table: 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

must be prepared separately.蘆For understanding the descriptions at the medium row of the Table: 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.

※continued from page 11For "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 the combination indicated 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.

＊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]

1. Our electric chain blocks(with the trolleys included), either DA type or DB type, are usually designed to operate on the 3-phase power source.

The electrical parts used for our chain blocks are all the precision ones which can normally operate even with an accidental voltage drop (with a 10% reduction of the rated voltage)

2. As standard, our lifting motor (LM) and trolley motor (TM) are respectively assured of the following ratings.

In the case of the DB type, however, its rating will be like:

3. As to the 4-core power cord, or the 7-core cabtyre cord used for the DAGC, DBGC, DAPC or DBPC type, they are each usually of 5m in length. The cords of other length than the above, or of special dimensions, are available upon request.

4. When connecting the power cord to the power source, take care of its correct phase so that the lifting motor can rotate in UP direction and DN direction according to the push of the UP button and DN button on the control switch. If the connection phase is reversed, the negative phase protector starts to work to prevent the lifting motor from rotating in either direction. If this occurs, exchange the connection phase of the black and red leads from each other: at the time, avoid changing the wire connections in the control switch, chain block and trolley.

5. The running direction of the electric trolley and/or the saddle has been decided at the shipment, and it may be changed, at your site, by changing the wire connection at the control switch case.

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.


Traversing, Traveling withTrolley and Saddle.

The electric chain block, while hoisting any of loads, may be moved in lateral or longitudinal direction when used in combination with a trolley or saddles which is fitted on a rail. Usually, the trolley is used for a lateral motion of the electric chain block and saddles for a longitudinal motion of it.And when the chain block moves laterally, we call it as "traversing" and when it moves longitudinally, we call it "traveling".Depending on your job requirements, the ELEPHANT electric chain blocks may be combined with different types of saddles of our own; refer to our catalog"ELEPHANT Electric Saddles".

Short Time Duty Rating andIntermittent Duty Rating

As a criterion to indicate the strength and durability of our electric chain blocks. We have specified the ratings of the short time duty and intermittent duty concerning their included electric motors-see the page 12 of catalogs. 蘆Short Time Duty Rating"Short time duty rating" means the limited time that the admissible temperature limit of its electric motor won't be exceeded, when the electric chain block is operated continuously on the below cycle.

蘆Intermittent Duty RatingCompared with "short time duty rating", the temperature of motor rises gradually by properly giving rests to the chain block between its operating periods (lifting and lowering). The percentage duty cycle ED is found as follows.

based on the maximum cycle period of 10 minutes. The number of starts/h also affects the rise of temperature. Thus these two factors are specified to show the intermittent duty rating of the electric chain block under the specification of which the electric motor can be operated safely without exceeding its admissible temperature limit.

Lift and Length ofPushbutton Switch Cord

笋

DEFINITION OF WORDS

As the electric chain block is operated, its bottom hook moves up and down and the longest distance of this motion is called a "lift". In other words, the lift refers to the distance between the bottom hook's highest position (with the upper limit switch actuated) and its lowest positon (with the lower limit switch actuated).The length of the pushbutton switch cord refers to the distance between the bottom of dimension L and the lower surface of the pushbutton switch case.
