Passenger Hoist Gear Coupling: A Key Spare Part for Construction Hoists
Q1. What Is a Passenger Hoist Gear Coupling?
A passenger hoist gear coupling is a mechanical component used to connect rotating parts within a drive system and transmit torque. It plays an important role in the power transmission assembly of construction passenger hoists.
For construction equipment operators and maintenance teams, selecting the correct gear coupling helps maintain reliable drive system operation and supports routine equipment maintenance.
Q2. Which Gear Coupling Models Are Available?
SYM supplies passenger hoist spare parts gear couplings in three specifications:
14kg gear coupling
17kg gear coupling
22kg gear coupling
These options are listed for GJJ and BAODA passenger hoist applications. Buyers should confirm the required dimensions and connection specifications before ordering to ensure compatibility with their existing equipment.
Q3. What Are the Main Specifications?
The product page provides the following reference specifications:
Bearing width: 121–123.5 mm
Large half thickness: 84 mm
Small half thickness: 74 mm
Elastomer thickness: 35 mm
Outer diameter: 205 mm or 210 mm
Large half aperture: 38 mm
Spline minor diameter: 35 mm
Spline major diameter: 40 mm
Operating speed: 1,500 rpm
Dimensions such as step diameter, hole length, spline length, and rotational inertia vary by model. Please refer to the product specification table and confirm the exact version required before purchasing.
Q4. Why Is Choosing the Right Gear Coupling Important?
The correct gear coupling helps maintain effective torque transmission between connected drive components. Incorrect dimensions or incompatible connections may cause installation difficulties, misalignment, or premature component wear.
When replacing a passenger hoist coupling, check the original part dimensions, spline configuration, connection type, and equipment model. Regular inspection can also help identify wear or damage before it affects normal operation.
Q5. How Can You Order Passenger Hoist Gear Couplings?
SYM supplies construction hoist spare parts for equipment maintenance and replacement. When making an inquiry, please provide the required coupling specification, hoist brand and model, quantity, and relevant dimensions.
Our team can help confirm the product configuration according to your requirements.
Whether you need a 14kg, 17kg, or 22kg gear coupling, selecting the correct replacement part is an important step in maintaining your construction hoist drive system.
