Main technical parameters of LH electric hoist bridge crane

I. Basic Parameters

  1. Lifting Capacity
    • The rated lifting capacity of the main hook ranges from 5 to 32 tons, with an optional auxiliary hook of 3 to 10 tons (depending on the tonnage of the main hook).
    • Specific to model 9-8-89698, it may belong to the 5-10 ton or 16-20 ton series; further confirmation of span and configuration is required.
  2. Span (S)
    • The standard span is 7.5 to 35.5 meters, with a common range of 7.5 to 22.5 meters (within the national standard).
    • The typical span for 5-10 ton models is 7.5 to 22.5 meters, and for 16-20 ton models, it is 7.5 to 35 meters.
  3. Lifting Height
    • The main hook lifting height is typically 6 to 18 meters, with options of 6, 9, and 12 meters.
    • The auxiliary hook lifting height is generally 2 to 4 meters higher than the main hook.

II. Operating Performance

  1. Working Class
    • Standard working classes are A3 to A5, suitable for medium-intensity operations (such as machinery manufacturing and warehouses).
    • The 10-ton model can be adapted to the A5 duty cycle (for frequent use).
  2. Operating Speed
    • Trolley operating speed: 20 m/min (driven by a ZDY series motor).
    • Trolley operating speed: 20 to 30 m/min (ground or cab operated).
    • Hoisting speed: 3.5 to 8 m/min (electric hoist model CD1/MD1).

III. Structure and Configuration

  1. Drive Mechanism
    • Hoisting motor: ZD151-6/13 (16 to 20 ton models) or CD1/MD1 electric hoist (5 to 10 ton models).
    • Trolley operating motor: YZR132M series (three-phase AC 380V, 50Hz).
  2. Wheel Load and Deadweight
    • 5-10 ton models have a maximum wheel load of 46-110 kN and a deadweight of 7.7-17.3 tons (ground-operated).
    • 16-20 ton models have higher wheel loads and require a reinforced track foundation.
  3. Control Methods
    • Supports both ground control (handlebar or remote control) and cab control.

IV. Environmental Adaptability

  • Operating Temperature: -25°C to +40°C, suitable for conventional industrial environments.
  • Power Supply: Three-phase AC 50Hz 380V, meeting national standards.
  • Unsuitable Applications: Flammable, explosive, corrosive gas, or dusty environments (customization required).

V. Customization Considerations

  1. Special Requirements: Specific span, lifting height, control method, and power supply requirements must be specified.
  2. Non-standard Design: Span exceeding the standard (e.g., >22.5 meters) requires a reinforced main beam structure.
  3. Certification Standards: Complies with JB/T3695-2008, GB3811-2008, and other standards.
