The OSL70 Series Overspeed Safety Lock is a type of safety device primarily used in equipment such as elevators or suspended platforms to prevent accidents caused by excessive speed.

Here is a detailed introduction:
 

Function principle: It typically operates as a centrifugal-triggered safety lock. When the equipment (such as an elevator or suspended platform) descends at a speed exceeding the preset value, the flyweights inside the safety lock generate a centrifugal force that overcomes the restraining force of the spring and flings outward. This action triggers the locking mechanism to lock the safety wire rope, thereby stopping the equipment from falling
 

Technical characteristics: Similar models, such as the OSL30 series, have technical parameters including a wire rope diameter of 9.1mm or 10.2mm, an allowable impact of ≥30KN, a locking distance of ≤200mm, and a starting speed in the range of 15 - 30m/min. Although the specific parameters of the OSL70 series may vary, they generally focus on indicators such as applicable wire rope diameter, allowable impact, locking distance, and starting speed.
 

Manual operation function: It is equipped with a manual - trigger handle, which allows operators to manually lock the wire rope, facilitating maintenance or emergency stop operations.

Application scenarios: Mainly used in scenarios where there is a risk of overspeed descent, such as in the suspended platforms of building exterior maintenance, elevator systems, and some lifting equipment, to ensure the safety of operators and equipment.
