Overhead electric hoist

Core Strengths & Key Features Of Overhead Electric Hoist

• 1. Robuste Konstruktion & High Load Capacity:

  • Built with premium-grade materials and precision engineering for maximum structural integrity.
  • Wide capacity range, typically from 1 ton to 80 Tonnen (and beyond with custom solutions), catering to diverse lifting needs.
  • Rigorous testing ensures reliability under full load and beyond.

• 2. Superior Lifting Performance:

  • Efficient high-torque motors provide smooth, powerful, and reliable lifting and lowering.
  • Multiple hoisting speeds (standard and optional variable frequency control) allow for precise load handling, minimizing swing and enhancing productivity.
  • Low headroom designs available to maximize usable workspace beneath the crane.

• 3. Verbesserte Sicherheit & Reliability:

  • Comprehensive safety systems: Upper and lower limit switches, overload protection, Notstopp, phase protection.
  • Fail-safe braking systems (dual brakes often standard) ensure secure load holding.
  • Heavy-duty wire rope and hook with safety latch, compliant with international standards.
  • Durable gearboxes designed for long service life with minimal maintenance.

• 4. Advanced Control & Operation:

  • Smooth operation via pendant control (available in various voltage options) or electric hoist with wireless remote control systems.
  • Optional Variable Frequency Drive (VFD) integration for ultra-smooth acceleration/deceleration, precise positioning, reduced mechanical stress, and energy savings.
  • Clear visibility and ergonomic controls enhance operator safety and efficiency.

• 5. Durability for Demanding Environments:

  • Designed for high duty cycles (Z.B., FEM 1Am, 2M, 3m classifications).
  • Options available for harsh conditions: corrosion-resistant coatings (epoxy/polyurethane), higher IP ratings for dust/water resistance (IP54, IP55, IP65), and heat-resistant variants.
  • Sealed components protect critical mechanisms.

• 6. Modular Design & Ease of Maintenance:

  • Modular construction simplifies installation, inspection, and maintenance.
  • Easy access to key components like brakes, motors, and limit switches.
  • Designed for long intervals between maintenance.
