2. Safety & Compliance
NANJING ZHUYE ELEVATOR PARTS integrates dual-channel safety relays that positively open the motor and brake circuits, preventing unintended elevator movement during maintenance. A mechanical key switch isolates normal operation mode, while LED indicators confirm power, brake release, and fault status at a glance.

3. Human-Centred Design
The ergonomically angled front plate reduces wrist strain for technicians working in confined hoistways. Braille labels and high-contrast icons ensure accessibility for visually-impaired service personnel. The low-profile 110 mm depth clears overhead beams in restricted overhead spaces.

4. Energy Efficiency
The inspection lamp consumes only 3 W yet delivers 240 lm, lowering battery drain during prolonged inspections. Stand-by power is < 0.5 W, contributing to overall lift energy savings certified by TÜV Rheinland.

5. Installation Flexibility
Pre-wired terminal blocks with colour-coded jumpers allow electricians to connect the box to any controller (OTIS, KONE, Schindler, Mitsubishi, etc.) in under 10 minutes. Optional stainless-steel bracket kits adapt to curved car roofs or side-rail mounting.

6. Applications
Ideal for high-speed passenger lifts, hospital bed elevators, freight platforms and scenic elevators where frequent top-car access is required.

7. After-Sales Support
