QY Insulation Overhead Crane

Isolation Crane & Insulated Crane 

Isolation crane also  called insulated crane  is a double girder overhead crane with the insulation crane hook. It a kind of material handling equipment used to lift and transport loads in charged environment, such as the plants where electrolyse non-ferrous metals, such as magnesium, aluminum. Isolation crane is a heavy duty overhead with double brake in the hoisting for ensuring safety. The lifting capacity of the isolation crane is 5 to 50 tons and the working class is A6. The specific parameters of the overhead crane is as follow:WaVHenan Dongqi Machinery Co., Ltd

Features of isolation crane

1. Insulation measures of isolation cranesWaVHenan Dongqi Machinery Co., Ltd

In order to prevent the crane and operator from danger of current to ensure their safety, there are three insulated devices equipped on the isolation crane, which are placed between:WaVHenan Dongqi Machinery Co., Ltd

  • the hook and pulley,
  • lifting mechanism and the trolley frame,
  • trolley frame and crane.

2. Bridge frameWaVHenan Dongqi Machinery Co., Ltd

As the main force component of isolation, the bridge frame is mainly consisted of double beam, double track, end beams, trolley tracks, walkways, railings, ladders, and other metal structures.WaVHenan Dongqi Machinery Co., Ltd

  • The main beams and end beams are structured with the box-shape, made of Q235 or Q345 steel, with the minimum thickness no less than 6 mm.
  • Main beam camber is (1 ~ 1.4) S / 1000, and the maximum camber position controlled within tenth of central span.
  • Trolley tracks which lay on the bridge is a whole railway to ensure the smooth moving of the trolley, and the insulating devices is placed between the trolley tracks and trolley wheels to ensure the insulating features of the isolation crane.

3. Driver’s cabinWaVHenan Dongqi Machinery Co., Ltd

Driver’s cabin is a closed and tempered glass cabin, which is the workplace of crane operator, therefore the driver’s cabin has to be durable, safe and reliable, and at same time it should provide the driver a good vision and enough comfortableness. The features of driver’s cabin are as follow:WaVHenan Dongqi Machinery Co., Ltd

  • Good vision, 270 ° viewing angle of the front range.
  • Reliable quality and easy to be cleaned and maintained.
  • High safety, cabin alarms, unobstructed walking and activity space, etc.

4. Crane traveling mechanismWaVHenan Dongqi Machinery Co., Ltd

The traveling mechanism of isolation crane: During operation, driving wheels never slip; when braking, it is steady and reliable.WaVHenan Dongqi Machinery Co., Ltd

5. Trolley partsWaVHenan Dongqi Machinery Co., Ltd

Main and auxiliary hoisting mechanisms of isolation crane have separate driving device, which can lift and handle loads independently and can coordinate to complete the work of turning loads over. Dual braking is used by the hoisting mechanism.WaVHenan Dongqi Machinery Co., Ltd

6. Isolation Crane Safety Protection DeviceWaVHenan Dongqi Machinery Co., Ltd

  • Overload limiter is installed on the main crane hook, which has the functions of weight display, overload alarming, and automatic power off.
  • Each mechanism is installed with closed electro-hydraulic brake while main lifting adopts dual brakes.
  • Lifting limit switch, overcurrent protection, no-voltage protection, phase protection, zero protection, emergency switch, the main isolating switch, hatch door interlock switch, bells prompt and other safety devices to ensure the normal operation of cranes and related personnel personal safety.
  • A few shock proof lamps can be installed under the bridge frame according to your needs.
