Reference Table for Standard Use JWM (Machine Screw Type)

1.All loads (static, dynamic or shock) should be within the rated capacity of the jack at sufficient safety levels.

2.Operating Temperature Range refers to the surface temperature of the jack during operation. To check, measure the surface temperature of the input shaft unit or travel nut (if used). Be sure all the rotating parts have completely stopped before proceeding to measure.

3.Be sure to operate within the allowable input rpm of 1800/min.

4.Number of synchronizing jacks which can be connected on the same line is limited by shaft strength. Refer to the allowable input shaft torque on the above table.

5.Activating torque for the drive unit should be maintained at 200% above the required torque.

6.If operating in freezing temperatures, a change in viscosity may reduce the efficiency of the grease. Set the drive unit so as to accommodate this change.

Note 1) The allowable torque is for jack input shaft only. (Reconfirm if synchronous drive.)

Note 2) Includes tare drag torque.

Note 3) Rotation prevention types for frames 002～050 are steel square pipes.

Note 4) Standard percentage duty cycle is 30 minutes. Thus, driving time is based on 30minute intervals.

*Note 2

7.Although JWM (Machine Screw Type) comes with a self-locking device, it may not be effective with vibration or shock. Use a brake under such conditions.

8.Be certain that the jack rating exceeds the maximum stroke. Over travel can cause the lift shaft to disengage from the worm wheel. JWM (Machine screw type) is not equipped with a fall stop, therefore, if the stroke range is exceeded, the screw shaft falls.

9.Do not use mechanical stops under any circumstances. This will cause major internal damage.

10.Input shaft key is provided with each unit. (Key complies with JIS B 1301-1996 standards.)

WarningCautions for selecting● Duty cycle of JW M (M achine screw type) is within 20% ED. Duty cycle is a ratio of operating tim e per 30 m in on the basis of 30

m in interval.

● Although JW M (M achine screw type) com es with a self-locking device based on calculation, it m ay not be effective due to

vibration or shock. Separately a brake m echanism is required under such conditions.

● Activating torque for the drive unit should be m aintained at 200% above the required torque.

● Allowable input rotation speed of linear power jack is 1800 r/m in, however, when inputting a speed exceeding the m axim um

input rotation speed at the basic capacity, check the screw shaft speed (elevation speed) and allowable load related graphs

on page 123.

● Select a stroke for the jack with an extra m argin with respect to the used stroke.

● Rotating force is generated on the screw shaft (travel nut in the case of travel nut type) with thrust, therefore, rotation prevention

is required. Screw rotation torque at the basic capacity is described in the standard specification list. W hen operating with the

end unconnected, and pulling the rope with a sheave installed, use the rotation prevention type.

However, the rotation prevention type cannot be m anufactured for the travel nut type, therefore, provide a rotation prevention

m echanism on the device.

● W hen installing a sprocket, gear, or belt to the input or output shaft, confirm that any overhang load applied to the shaft

decreases to the allowable OHL or less.

Precautions for installation● Jacks that range under the basic capacity of 49.0 kN {5tf} or less are provided with screw covers m ade of hard vinyl chloride

pipe. Never suspend or carry a jack by use of the screw cover, which is dangerous.

● JW M (M achine screw type) is not equipped with a fall stop, therefore, if the stroke range is exceeded, the screw shaft falls.

● Take jack coasting am ount into consideration to set the stroke adjusting lim it switch.

Precautions for use● Do not use m echanical stops under any circum stances.● Operating Environm ent for jack is as follows.

● Operating part and reducer unit are factory greased. Therefore, use jack as delivered.

● For lubrication grease, lubrication cycle and lubrication am ount to the screw shaft and reducer unit, refer to page 223.

● Inspect regularly for general backlash and screw unit condition. Jack life and replacem ent tim ing are determ ined by the

following:

Backlash in the direction of screw shaft and nut reaches 1/4 of the screw pitch.

Replace gear when its input shaft exceeds 30 rpm with backlash (rattle between input shaft and worm wheel) at H speed, or

exceeds 60 rpm at L speed.

In either case, if it is used at the replacem ent tim ing, this m ay cause rotation failure of screw shaft and input shaft, and further

sudden drop of travel nut.
