5Ton Double Beams Insulation Type EOT Crane

Insulation Overhead Bridge Crane Description: 

QY model insulating overhead crane is widely used in electrolyzing of nonferrous metal, aluminum and magnesium metallurgy workshops. Insulation overhead bridge crane is composed of box-type frame, crane travelling mechanism, trolley, electric equipment. In order to prevent the current of electrical equipment would through lifted parts endanger the driver of Insulation overhead bridge crane during working, the insulation equipment is set up at some suitable positions.

It has over three insulation parts to protect the current of electrical equipment from endangering the driver of the crane when working. Insulation overhead bridge crane belongs to heavy working grade, in order to secure safety; main hoist mechanism is matched with double brakes.

Insulation Overhead Bridge Crane Three insulating apparatus:

1.Hook and pulley

2.Lifting system and trolley frame

3.Trolley frame and crane

4.Every insulating apparatus resistance value should be not less than 1MΩ when temperature is 20~25℃ and relative humidity is ≤85%.

Insulation Overhead Bridge Crane Mechanical Parts:

Double welding box girder, beam deflection with DIN/FEM standard

Steel Material: Chinese standard Q235B and Q345B

Trolley rail is made of high strength hot rolled flat steel (16 Mn)

Epoxy zinc-rich painting for one bottoms and two sides of 120μm thick, to achieve a long lifespan, beautiful appearance and good luster

The girder and end beam are connected together by high strength bolts to ensure the structure strength and precision of the whole machine
The end beams are equipped with flat wheel or double rim wheels, anti-friction bearings, buffer blocks and derailment preventing end plate
Maintenance walkway is located on one side of the main girder, consisting of flower pattern plate, 1050meters handrail.

Insulation Overhead Bridge Crane Safety protection system:

1.Overload protection in the event of overload, the hoist unit switches off and only the lowering motion is possible

2.Long and cross travel limited by means of preliminary and final limit switches or Wireless anti-collision device

3.Anti-falling protection for the Three-in-One electric motor of trolley and crane prevents from accidental falling

4.All movements can be switched off by actuating the emergency-off switch at the control station via a main contact

5.High quality long time bearing polyurethane materials buffer fixed at the end of trolley travelling and crane travelling to prevent over traveling

6.Safety hook latch used for avoiding the lifted material out off from the hook

7.Audible and visual alarm device to inform the person stay near by the travelling crane.

8.Rain Cover for lifting mechanism of outdoor cranes, electric cabinet and driving mechanism

9.Protective earth conductor is fitted as standard

10. Voltage lower protection system

11.Current overload protection system
