LPT series electric cylinder

LPT series electric cylinder

Specifically for applications in high load and harsh environments, the thrust can reach 90 tons, equipped with high-efficiency heavy-duty ball screw, power transmission with high-frequency work system, and the perfect combination of brakes, limit switches, and thrust overload limiters. Performance Reliable and stable, it is widely used in ports, steel, mining and other machinery.

The principle of the thrust overload function is that when the bidirectional load exceeds the rated load of the push rod, there are two sets of micro switches in the overload mechanism to act. This switch must be connected to the control loop corresponding to the extension and retraction of the push rod. This function It can take effect. When the normally closed switch action becomes an open circuit, the circuit will be de-energized and the motor will be de-energized and will not work. The push rod will stop working immediately to ensure that the push rod will not block the motor due to overload. Turn burnout or damage to the mechanical part of the push rod, the motor brake can effectively hold the load to achieve self-locking, and can be equipped with manual release. Accessories: can be equipped with built-in cam limit switches, external mechanical limit switches, potentiometers, and dust covers. Ambient temperature: -15℃-50℃. Protection level: IP44, IP55, IP56, IP65, etc. Special requirements need to consult business engineers.

LPT series TB, TC type (model and ordering instructions)

The TB and TC models have the same basic functions (thrust, speed and stroke), and both have the following mechanical devices with thrust limits.

• As a facility to prevent overload, a built-in slip clutch is installed inside, and the clutch is activated when the thrust load exceeds a preset value.

• When overload or excessive operation occurs at the end of the stroke, the individually designed friction lining can ensure smooth operation.

TC type features: thrust detection type

• The internal thrust detection system includes two coil springs with different elastic coefficients. When the thrust load exceeds a preset value, an electric signal is sent to the control circuit by turning the limit switch, so that the circuit is de-energized, and the motor is finally stopped and pushed. The pole stopped.

Note: 1. When using LPTC-M and LPTC-H, the brake connection must be separated.

2. Please refer to page 15 for the thrust limit when marked with * stroke.

TB type characteristics TC type characteristics

• Economical TB

• TC with overload function

Standard

Note: 1. Only the allowable torque of the input shaft. (Please pay attention when the link is running) 2. This torque includes the no-load torque.

Environmental conditions

Note: 1. These environmental conditions only apply to the main body of the power cylinder, and the motor or other optional parts may have different requirements.

2. It is recommended to use a dust cover for the dirty or dusty surrounding environment.

3. For use near the ocean, improved paint and limit switches are required, and protective measures are recommended to prevent corrosion.

Note: The motors of the LPT series electric actuators can be equipped with single-phase AC motors and servo motors. The parameters have changed, please contact your local engineer.
