To prevent equipment from losing control of its lifting height during operation, causing accidents such as toppling, derailing, or falling, it is necessary to installQGX lift height limiter<\/strong>To protect the equipment from operating within a safe range and prevent accidents. The micro special QGX type lifting height limiter can provide effective protection for the safe operation of displacement machinery and equipment.<\/p>\n

\"QGX
\nQGX lift height limiter<\/a>The worm gear is driven by the roller shaft, causing the cam on the worm shaft to rotate as well. When the cam reaches a certain position, its protruding part contacts the limit switch, activating it to cut off the power source for ascent or descent, stopping the lifting gear at the extreme position. The QGX lifting height limiter is equipped with four to eight limit switches, which can be set according to user needs. Generally, two levels of protection can be set for both ascent and descent, namely alarm limit and protection limit. This device is suitable for various types of cranes, elevators, lifters, and other equipment with displacement mechanisms, effectively preventing equipment and personnel accidents such as roof-top collisions, derailments, and falls.<\/p>\n

Core advantages\uff1a<\/h2>\n

High universality: Limit adjustment possible, suitable for equipment with displacement mechanisms such as various cranes, elevators, lifters, etc.
\nPrecise and Reliable: Certified through type tests of special equipment, with a normal service life of over ten years.
\nEasy installation: Simple to install, with positive feedback from many users who have installed it themselves over the years, and good feedback on self-resetting and relocation.<\/p>\n

\"Lift<\/p>\n

To better adapt to different specifications of lifting mechanisms, the QGX type lifting height limiter provides three models for everyone to choose from:
\nQGX- A Type: Suitable for lifting mechanisms of standard 5T to 250T crane series or non-standard drums with a winding number of 0 to 40, equipped with limit switches that can be adjusted to four to six positions.
\nQGX-B type: Suitable for lifting mechanisms of standard 5T to 250T crane series or non-standard drums with a winding number of 0 to 80, also equipped with limit switches that can adjust four to six limit positions.
\nQGX-C model: Suitable for the standard series of 5T to 250T cranes or non-standard winding drums with a lift circle of 0 to 120 circles, equipped with limit switches that can adjust four to eight limit positions, making limit adjustment more flexible.<\/p>\n
