Core Components & Superior Engineering

1. Robust Bridge Structure:
- Capacity: Rated for safe lifting of loads up to 2 톤 (4,000 lbs / 1814 kg) with a minimum 25% design safety factor overhead.
- Construction: Fabricated from high-tensile strength steel. Choose between rigid Box Girder (superior rigidity, precise load control, longer spans) or cost-effective Single Girder (I-beam design, ideal for lighter duty cycles and shorter spans).
- 기간: Custom-engineered to fit your specific bay width (Clear Span), maximizing your floor space utilization.
- Rigidity: Precision-welded and machined for minimal deflection under load, ensuring smooth operation and accurate positioning.
2. End Trucks & Runway System:
- Durable End Trucks: House heavy-duty wheels and drive mechanisms (crane gearbox, motors) for smooth bridge travel (X-axis).
- Precision Runway Beams: Engineered steel beams (typically I-beams or S-beams) securely mounted to building columns or support structures, providing the track for the entire crane.
- Travel Drives: Reliable AC motors with sealed gear reducers ensure consistent and controlled bridge movement along the runway.

3. High-Performance Hoist & 트롤리:
- 전기 와이어 로프 호이스트: A robust 2-ton capacity hoist (기준) features:
  - Lifting Motor: Thermal protection, adequate power for smooth starts/stops.
  - Wire Rope & Drum: High-grade steel rope on a machined drum for long life.
  - Precision Braking: Fail-safe dual braking systems (primary mechanical + secondary emergency/parking).
  - 크레인 후크: Forged steel safety latch hook rated for 2 톤.
  - Lifting Speed: Standard speeds (~8/2 m/min lift, ~20 m/min traverse); VFD control optional for ultra-precise handling.
- Trolley Unit: Transverses the bridge girder (Y-axis), carrying the hoist. Features driven wheels or motorized movement for precise load placement.
4. 고급 제어 & 안전:
- 펜던트 제어: Standard ergonomic, low-voltage pendant station (IP65 rated) for intuitive operation (Up/Down, Bridge Left/Right, Trolley In/Out). Cable-reel options available.
- 라디오 리모컨: Optional wireless freedom for the operator, enhancing visibility and safety.
- Comprehensive Safety Features:
  - 상한/하한 스위치 (Hoist Travel)
  - Bumper/End Limit Switches (Bridge & 트롤리 여행)
  - Overload Protection System (Mechanical or Electronic)
  - Emergency Stop Buttons
  - Safety Latches on Hooks
  - Compliance with ANSI/ASME B30.2, OSHA 1910.179, CMAA 74/78 (or relevant ISO standards).

Important Notes:

1. Customization: Almost all parameters (기간, 리프팅 높이, Speeds, 제어, Girder Type) are customizable to specific application needs.
2. Structural Support: Wheel Load is the MOST CRITICAL parameter for your building’s structural engineer. The crane supplier provides this value based on the final design; the building must support it.
3. VFD (Variable Frequency Drive): Highly recommended for smooth acceleration/deceleration, precise positioning, reduced mechanical stress, and operator comfort. Adds cost but significant benefits.
4. Duty Class: Defines usage intensity (e.g., hours/day, lifts/hour, average load). Class A (Infrequent/Light), B (Light/Moderate – *most common for 2-ton*), C (Moderate/Heavy).
5. 호이스트 유형: Wire Rope Electric Hoist is standard. Chain hoists are possible for very low headroom but less common at 2-ton capacity.
6. Installation: Requires professional installation by certified crane erectors, including final load testing and certification.
