Zoomlion SC200/200 Construction Hoist – Technical Specifications

1. Key Operating Parameters

• Rated Load Capacity: 2 × 2000 kg

  • (This is the load for each independent cage, meaning each can carry a maximum of 2000 kg or approximately 26-27 passengers).

• Rated Lifting Speed: 0~66 m/min

  • (Modern hoists typically feature Variable Frequency (VF) control, allowing speed to be smoothly regulated from zero to the maximum).

• Maximum Lifting Height: 450 meters

  • (This is the maximum designed attachment height; the actual working height depends on the site plan and attachment scheme).

2. Cage Dimensions & Structure

• Internal Cage Dimensions (L×W×H): Typically 3.2 m × 1.5 m × 2.4 m

  • (This spacious design can easily accommodate a standard construction material pallet or provide ample space for workers).

• Standard Features: Typically includes an intercom system, emergency stop buttons, limit switches, and a fall-safe device, among other safety features.

3. Mast Section & Tower Structure

• Mast Section Specification: Typically a 650 mm × 650 mm × 1508 mm tubular structure.

• Mast Section Material: High-strength steel.

• Erection Method: Stabilized via tie-in (attachment) brackets connected rigidly to the building structure, ensuring overall stability.

4. Drive & Electrical System

• Drive Type: Triple-motor drive (i.e., each cage is powered by three independent motors), providing powerful and smooth operation.

• Motor Power: Each motor is typically 7.5 kW or 9 kW (subject to configuration), resulting in a total power of approximately 22.5 kW or 27 kW per cage.

• Control System: Variable Frequency (VF) Control. This ensures smooth acceleration and deceleration, minimizing impact on the structure and electrical system, and providing a comfortable ride.

• Power Supply: Typically 380V, 50Hz, 3-Phase, 5-wire system.

5. Safety Devices

• Fall-Safe Device (Safety Gear): The most critical safety component, designed to automatically stop and hold the cage in the event of overspeed or failure. The SC200/200 is typically equipped with a progressive-type fall-safe device, such as the SAJ40-1.2A model, with a tripping speed range of 0.7~1.2 m/s.

• Electrical Safety Circuit: Includes upper and lower limit switches, final limit switches, and door interlock switches.

• Mechanical Safety Devices: Buffers (installed on the base frame to absorb the impact energy of the cage landing).
