Height Limiter For Tower Crane Cam Rotary Height Limit Switch
1、 Core Features of Industrial Crane Safety Limit Switch/heavy duty overhead crane components/Dxz 6N limit switch
Space coordinate control
industrial crane safety limit switch/ heavy duty overhead crane components/Dxz 6N limit switch Through the linkage of mechanical memory cam and micro switch, bidirectional deceleration (or alarm) and endpoint limit protection of the motion mechanism are achieved.
Typical scenario: lifting limit, amplitude control, and rotation protection of crane hooks.
Synchronization of displacement signals
External sensors (potentiometers) can output electrical signals and are paired with display instruments (such as ZXY type) to provide real-time feedback on the spatial position status of the equipment.

3、 Key points for installing and adjusting the industrial crane safety limit switch
industrial crane safety limit switch/Dxz 6N limit switch disassembly steps
Disassemble the upper cover → tighten the internal screws (M3 × 55) → loosen the adjusting nut (M5) → adjust the memory cam position → lock the nut → verify no-load operation.
industrial crane safety limit switch/Dxz 6N limit switch/industrial crane safety limit switch synchronous calibration
After moving the controlled mechanism to the target position, rotate the adjustment shaft (Z) to accurately trigger the micro switch (WK) with the cam (T).
Maintenance requirements for Dxz 6N limit switch
Regularly check the accuracy of the memory position to prevent control disorder caused by loose nuts.
4、 Typical application scenarios of industrial crane safety limit switch
Dxz 6N limit switch for heavy-duty machinery: Three coordinate limit switches for construction tower cranes, port cranes, and mining transmission equipment.
Dxz 6N limit switch safety protection: lifting over limit protection, amplitude terminal deceleration, rotation collision prevention.
Dxz 6N limit switch industrial display: equipped with ZXY instrument to achieve visual monitoring of travel (such as hook height and boom amplitude).
