Elevator Door Knife SAC-01: Core Door System Component from Nanjing Zhuye Elevatorparts
The elevator door knife is a critical mechanical component of the elevator door system, installed on the car door to drive the landing door to open and close synchronously. Its precision and stability directly affect the safety, smoothness, and service life of the elevator door system—accounting for a large proportion of elevator failures. The Elevator Door Knife SAC-01, exclusively supplied byNanjing Zhuye Elevatorparts, is designed for passenger and freight elevators. Compliant with international standards such as EN 81-1 and GB 7588.1-2020, this door knife features a rigid integral structure with high mechanical strength (mechanical life ≥1 million cycles) and precise dimension control. It is widely compatible with mainstream elevator brands including Schindler, OTIS, KONE, and domestic well-known brands, applied in residential buildings, commercial complexes, airports, and industrial parks to ensure reliable coordination between car doors and landing doors.
Nanjing Zhuye Elevatorparts adheres to stringent quality control standards, and the SAC-01 elevator door knife is a testament to this commitment. Each door knife undergoes rigorous pre-delivery testing, including dimensional accuracy calibration, wear resistance testing, high-low temperature (-25℃ to 85℃) resistance tests, and impact resistance verification. The blade is made of high-quality carbon steel with quenching treatment, ensuring hardness (HRC ≥55) and wear resistance. The connecting shaft adopts a precision bearing structure to reduce friction during operation, avoiding abnormal noise. The surface is coated with anti-corrosion paint to resist dust and moisture erosion in the hoistway. The design fully considers the matching with landing door locks, ensuring smooth insertion into the lock roller without jamming or excessive wear.
Usage Guide for Elevator Door Knife SAC-01
Proper installation, adjustment, and daily maintenance are vital to maximizing the performance and service life of the SAC-01 door knife. Nanjing Zhuye Elevatorparts strongly recommends that only certified elevator maintenance technicians perform these operations to avoid door system failures or safety hazards. Before installation, verify that the door knife model (SAC-01) matches the elevator’s door machine and landing door specifications. For detailed installation positions and gap adjustment standards, refer to the product manual provided by Nanjing Zhuye Elevatorparts or contact our technical support team for professional guidance. Note: Ensure the elevator is in maintenance mode and the main power is cut off during operation, and place a warning sign at the landing entrance.
1. Pre-Installation Preparation
First, cut off the elevator’s main power supply and lock the switch, and manually move the car to the middle floor to ensure a safe operation space. Prepare professional tools: torque wrench, screwdrivers, feeler gauge, level ruler, wire brush, and anti-rust spray. Clean the installation position on the car door panel to remove dust and rust. Carefully inspect the SAC-01 door knife for external damage (e.g., bent blade, damaged bearing) and check the matching landing door lock roller for wear or jamming—replace damaged parts in advance to ensure smooth coordination.
Fix the SAC-01 door knife on the car door bracket with high-strength bolts, and use a level ruler to ensure the blade is vertical (tolerance ±1mm). The core adjustment step is to control the gap precisely: 1) Adjust the distance between the door knife and the landing door sill to 7mm using gaskets; 2) Adjust the gap between the blade and the landing door lock roller to 7±1mm—measure multiple landing doors to ensure consistency; 3) Ensure the two pushing surfaces of the blade are vertical to avoid uneven force during operation. Tighten the fixing bolts according to the torque specification (M10 thread: 12N·m) to prevent loosening from long-term vibration. Install a buffer pad at the contact point to reduce impact noise.
After installation, restore power and conduct debugging. Operate the elevator in maintenance mode to run through all floors, verifying that the SAC-01 door knife drives the landing door to open and close smoothly without jamming or abnormal noise. Check the gap again after 10 consecutive switch cycles to ensure no deviation. For daily maintenance, follow TSG T5002—2017 regulations: Inspect the door knife monthly for loose bolts, blade wear, or bearing jamming; clean the blade and lock roller with a wire brush to remove debris. Check the gap quarterly using a feeler gauge. For elevators in high-traffic areas or harsh environments, increase the inspection frequency to twice a month and spray anti-rust agent on metal parts.
Replacement Cycle of Elevator Door Knife SAC-01
The replacement cycle of the SAC-01 door knife depends on usage frequency, operating environment, and maintenance quality. Under normal conditions—12-24 hours of daily operation, regular maintenance, and moderate traffic—Nanjing Zhuye Elevatorparts recommends a replacement cycle of 3-5 years. This cycle is formulated based on extensive field test data and relevant industry standards, fully considering key factors such as blade wear, bearing aging, and reduced gap precision caused by long-term mechanical friction and environmental erosion.
For elevators in high-traffic areas (e.g., airports, subway stations with daily operation over 20 hours) or harsh environments (high humidity, heavy dust, frequent vibration), the replacement cycle should be shortened to 2-3 years. High-frequency switch cycles accelerate blade and bearing wear, and harsh environments easily cause corrosion and structural deformation. For low-usage elevators (e.g., villas, small offices with daily operation <8 hours), proper maintenance can extend the cycle to 5-6 years. However, Nanjing Zhuye Elevatorparts’ technicians should conduct semi-annual comprehensive inspections on door knives over 4 years old, including dimensional accuracy and wear condition tests.
Regardless of service life, replace the SAC-01 door knife immediately if: The blade is severely worn or bent, unable to drive the landing door normally; the bearing is stuck, causing abnormal noise or unsmooth operation; the gap with the lock roller exceeds 10mm and cannot be adjusted; the door knife causes frequent door system failures (e.g., failure to open/close, landing door bouncing); the surface is severely corroded, affecting structural strength; it fails to pass annual safety inspections. Use genuine SAC-01 door knives from Nanjing Zhuye Elevatorparts to ensure compatibility and door system safety.

2. Installation & Wiring
Align the ANCT-ES1-TF1 interface board with the mounting bracket inside the control cabinet and fix it with screws. Note that the tightening torque should be appropriate (20-30 N·m recommended) to avoid damaging the PCB substrate. According to the wiring diagram provided by Nanjing Zhuye Elevatorparts, connect the power wires (DC 24V) and signal wires (CAN bus lines) to the corresponding terminals of the elevator main controller and peripheral devices. The wire stripping length should be controlled at 6-8mm, and terminals must be tightened firmly to prevent poor contact. Separate power wires and signal wires to reduce electromagnetic interference, and use cable ties to organize the wires neatly. After wiring, install the protective cover and double-check for wrong or missing connections—incorrect wiring may cause protocol mismatch or communication failure.
