Hitachi waterproof escalator parking lock not only inherits all the advantages of the Hitachi escalator parking lock system but also especially strengthens the waterproof and moisture-proof functions to ensure the safety and stability of the escalator parking lock. The use of waterproof material technology ensures that the lock body and electronic control unit are fully waterproof and can work normally even in long-term water immersion or high-humidity environments, effectively preventing electrical failures or mechanical damage caused by water seepage. In addition to the conventional mechanical locking device, a waterproof sealing ring and drainage design are also added to further enhance the sealing and durability of the lock body.
