Q1: What is a Passenger Hoist Spare Parts Rack?
A Passenger Hoist Spare Parts Rack (gear rack) is a linear gear component mounted vertically on the mast section of a construction lift or passenger hoist. It meshes with the motor's driving pinion to convert rotational power into smooth vertical movement up and down the structure.
Q2: What are the key specifications and materials?
All racks are manufactured from high-strength C45 steel for high load capacity and wear resistance. Standard models include:
Mould M5: 40 × 40 × 1508 mm, C45 material
Mould M8: 40 × 60 × 1508 mm, C45 material
Mould M10: 50 × 50 × 1508 mm, C45 material
Q3: Which equipment brands use these gear racks?
Our racks are designed for exact compatibility with major construction lift and tower crane manufacturers, including:
Yongmao
SCM
SYM
ZOOMLION
Q4: Why is the gear rack critical for hoist operation?
Drive Transmission: It is the primary mechanical link enabling the hoist cage to ascend and descend reliably.
Operational Safety: Precision tooth engagement prevents slipping and excessive vibration, ensuring safe transport of workers and materials.
Emergency Braking: The anti-fall safety device directly engages the rack to instantly halt the cage in overspeed situations.
Q5: When should a gear rack be replaced?
Replace gear racks immediately if you observe:
Excessive tooth wear exceeding manufacturer safety limits.
Cracked, chipped, or broken teeth.
Severe corrosion or pitch misalignment at mast section joints.
Abnormal noise or backlash during movement.
Q6: How to ensure proper maintenance and installation?
Joint Alignment: Align tooth pitch accurately across connecting mast sections during assembly.
Regular Lubrication: Keep gear teeth coated with heavy-duty grease to reduce wear and friction.
Pinion Check: Always inspect the drive pinion when replacing a rack to prevent premature tooth damage.
