120 Ton Overhead Crane

120 Ton Overhead Crane

QD20-18.5m double girder bridge cranes are divided into two grades: A5 and A6. A5 grade is suitable for general mechanical processing and assembly workshops, metal structure workshops, mechanical maintenance workshops, etc., where work is not so frequent. A6 grade is suitable for work comparison. Frequent metallurgy and foundry workshops assist in lifting and continuous production. The crane has two operating modes of the ground and the control room. The control room has two structures: open and closed. The recommended ambient temperature is -25°C to 40°C, and the relative temperature is ≤80%. Rain equipment.

  1. The lifting frequency conversion system adds a 2x light-load increase function to increase production efficiency.

  2. Lifting upper and lower limits We adopt the latest (technically introduced from Germany) worm-type four-breakpoint adjustable limit and additional safety functions such as upper and lower pre-deceleration.

  3. In the operating system, an additional variable-frequency point-accurate positioning function is provided to meet the demand for mold clamping and mold division in the actual production.

  4. Collision avoidance between driving and driving changes the traditional old-style limit switch and anti-collision bar, upgrade to a safe and reliable double-breakpoint laser ranging anticollision, such as 7-8 meters deceleration, 2-3 meters parking, The distance can be adjusted according to the actual needs of the site.

  5. The vehicle control system adopts the modular control of the independent units of each institution to facilitate maintenance inspection in the future. The PLC and inverter use point-to-point direct control to improve anti-jamming capability, precise control and safety.
