We recommend using models with servo motor. With three-phase motor type, please choose the rotary encoder option ［Option code：E］.

With the fixed load, the stopping accuracy is ±1mm.

Multi-point stopping is possible with servo motor types, as well as the  three-phase motor types  with rotary encoder［Option code：E］.

The following methods are available for operation of multiple units.
・With a three-phase motor (inverter control)
As a speed error due to motor sliding occurs, turn on all the power at the same time for starting and stop with the position detection signal of each Lift Master to prevent cumulative errors.
・With servo motor
The servo motor control suppresses speed fluctuations and variations in stop accuracy.
・Mechanical synchronized specification
Multiple Lift Masters connected by couplings are driven by a single gear motor.

In principle, downward pressing function is not available.
Under certain conditions, it can be made available as MTO product.

Basically not required for standard models. However, supporter may be required depending on the operating conditions (acceleration / deceleration, OHL, etc.).

The maximum stroke of the standard specification is 1500 mm, but it can be manufactured with the desired stroke up to 2000 mm after checking the lifting load and OHL conditions.
Strokes longer than 2000 mm can also be manufactured under certain operating conditions. Contact us for more information. ※The longer the stroke, the larger the amount of tilt of the Lift Master, so please contact us.
※The structure of the Lift Master is basically the same as the standard specification up to a stroke of 2000mm. However, it may differ depending on the load conditions. Contact us for more information.

The standard specification is floor installation only.
The load receiving direction is downward (vertical direction) only.
When mounting horizontally or hanging is required, contact us for special arrangement. ※The Lift Master cannot be used for pressing stop applications.

For standard specifications /U speed, the maximum is 150 mm/s with a three-phase motor and 166 mm/s with a servo motor.
Contact us when higher speed operation is required by inverter control. Consider the allowable speed based on the operating conditions of the lifting load and speed, and the operation cycle.
In addition, by changing to the optimum screw and drive unit for the required speed as a "high-speed specification", it is possible to support up to 500 mm / s. ※The appearance of the Lift Master differs from the standard specification due to increased rigidity. Contact us for more information.
※Sudden acceleration or sudden stop may result in deterioration of stop accuracy or vibration of the work. When driving at high speed, set an acceleration / deceleration time and make a soft start / soft stop.

In order to make the lower limit position of the arm closer to the floor, the motor can also be mounted on the top.
However, the balance between the Lift Master unit and the motor will determine whether it is possible or not. Contact us for more information.
In addition, "low profile specifications" that suppress the height of the Lift Master itself are also available.
This specification is effective when there is space limitation of height. ※The mechanism of the "low profile specification" is significantly different from the standard, so please contact us.

The allowable load hourly rate * of the standard ball screw type is 30% ED.
Higher frequency is also possible. We will consider it according to the usage conditions (lifting load, speed, operation cycle, OHL load, ambient temperature, expected life).
The allowable load rate of the trapezoidal screw is 20%ED or less. ※For higher frequency, please contact us as it differs from the standard specifications.
※The load hourly rate %ED indicates the ratio of operating time per cycle. Load hourly rate% ED = "Operating time" / "Operating time + Stop time" x 100

If the position of the center of gravity is within the arc of the overhang amount, the allowable OHL can be judged from the OHL load curve.
When exceeds the allowable OHL of the standard specification, special "high rigidity specifications" with reinforced guides is available. ※The appearance of the high-rigidity specification of the Lift Master differs from the standard specification due to the increased rigidity.

The table below shows the reference values for the amount of tilt at allowable OHL at the stroke upper limit.
For other strokes, please contact us. ※If you want to reduce the amount of displacement, "high rigidity specifications" is available, so please contact us for more information.

The expected lifespan of the Lift Master is determined by the expected traveling distance life of the screws.

Trapezoidal screw type (LMEM)

Ball screw type (LMEB)

Expected traveling distance (km) = Actual load stroke (m) × Frequency of use (/day) × Number of operating days/year × 10^-3 × Expected number of years

P_M = P_MIN + 2 × P_MAX3

P_M : Equivalent load N  P_MIN : Minimum load N  P_MAX : Maximum load N

Estimates of coasting distance and stopping accuracy when descending are as follows. · LMEB0200H ... Coasting distance : about 1.5mm / Stopping Precision : about ±0.5mm
· LMEB0500H ... Coasting distance : about 1.3mm / Stopping Precision : about ±0.4mm
· LMEB1000H ... Coasting distance : about 1.1mm / Stopping Precision : about ±0.4mm Since the lifting speed is fast for H speed and U speed, provide an acceleration/deceleration time by inverter control for use.
The above value is a guide when the inverter decelerates (6HHz) and then stops.
The brake connection is made by AC external operation. The time lag of the relay is assumed to be 0.03s. ※The coasting distance and stop accuracy values will differ depending on the wiring method and speed, so please contact us.
※When higher stopping accuracy is required, consider using a servo motor.

With the ball screw type LMEB, the servo motor is standardized.

Changing the mounting direction of the motor is available as an option. [Option symbol: D1 to D3]
Contact us when changing the motor mounting position.

As an option, position detection sensors (option code: [L1 to L3]) are available.
The standard product is equipped with 4 position detection sensors (2 for S speed only), and sensors can be added as an option, but the number of sensors that can be added varies depending on the speed. If you would like to add more sensors, please contact us.

It's possible to change the material of covers and some parts ( other than strength parts) into stainless.

No. The necessity of bellows has to be decided when selecting the product.

Special support is available. Please contact us.

It depends on the use conditions. (Temperature, frequency, load)  Please consult us for details.

The Lift Master has an open structure, so the cleanliness cannot be guaranteed. However, measures to reduce dust generation from each component are possible. · RAYDENT^® (Ball screw・Guide)
· Stainless steel cover
· Clean grease applied (ball screw / guide)
· Baking painting

The Lift Master is for indoor use, so it is not intended for use in places exposed to water.
If the product is exposed to dripping water, provide a cover on the customer's device or take special measures as shown below. · Opening opposite side spec.: The opening of the Lift Master is arranged on the opposite side of the conveyance surface to prevent water from entering from the conveying surface side.
· With front bellows [Optional code: J] ・ ・ ・ A bellows is provided at the opening to prevent water drops from entering. ※The specifications of "Opening opposite side" and "With front bellows" have different structures from the standard, so please contact us.
※Since the Lift Master has an open structure, the above specifications are a simple drip-proof structure and do not guarantee waterproofness.
