One-Stop Warehousing Logistics Solution

 With the development of the warehousing industry and the rise of the online business model, smart warehousing has become an important concern for many e-commerce businesses. In order to reduce manpower allocation and save warehouse space, intelligent stacking cranes came into being and became one of the core equipment of intelligent storage. Based on the customer's market orientation, Weihua has successfully developed and manufactured warehouse stacker crane system, which can effectively ensure the safety of operators.

 

Warehouse stacker crane

 

The stacker has a rated load of 1.5t, and each pallet can carry equipment with a volume of 1.2m (length) * 1.2m (width) * 0.7m (height). The basic shelf has 28 columns, 7 rows, 8 layers, a total of 1568 cargo spaces, and a total load of 2352t.

 

Warehouse stacker crane has strong applicability and wide application:

The warehouse stacker has strong applicability and can be used in production workshops, large retail beverage supermarkets, and warehouse storage of pharmaceutical companies. It suitable for various industries such as chemical industry, textile, auto parts, electronic products, supermarket warehouse, etc.

 

Systems:

1. Crane system: crane positioning system, anti-sway system, human-computer interaction HMI, crane remote control, wireless network settings, background server and crane body control, etc.

2. Warehouse management system: WCS management and WMS management, code scanning device, warehouse management system software, video monitoring system, wireless and wired network system, production docking MES interface.

3. The safety and warning system of the storage area: safety management of the working area of the crane, safety management of the ground sidewalk, safety management of the vehicle passage, various safety management indicators, alarms and safety barriers, etc.

 

Save power and improve efficiency:

1. The suspended stacker is mainly used in conjunction with the shelf, and is convenient to move during use, can save power, and save the occupied area of the stacker at the same time. 　　

2. The automated 3D warehouse stacker brings great convenience to the logistics transportation industry and the large-scale warehousing industry. The stacker can not only improve the efficiency, but also reduce the damage rate of the goods. The stacker can protect the surface of the goods from damage to the greatest extent in the process of working.

Crane Cable Carrier / Weihua Crane

 The crane cable carrier is used for the suspension and movement of the cables of the crane for mobile power supply, which has been widely used in various lifting machinery with the features of sturdy structure, mobile and flexible, Safe and reliable. This cable carrier can hold flat cable and round cable, running under C-rail or I-rail.

 

crane cable carrier

 

The cable carrier is device helping power supply of the crane trolley or hoist. It is composed of walking wheels, brackets, and pallets. The cable is hold on the pallet, and the traction frame is synchronized with the cable trolley to achieve the power supply for the trolley. Weihua cable carriers are divided into medium load type, heavy load type and light load type. Therefore, the wheels are Ф80, Ф63 and Ф50. And the load capacity is ≤50∽150kg. The pallet layers can be single Layer, double layer, and triple layer. The carrier at the head end is a tractor carrier, the end is a fixed cable rack, and the middle is the cable trolley.

 

 

Note:

1. After the fixed cable rack is installed, a baffle should be hung on the back;

2. Adjust the traction head so that the trolley does not touch the upper and lower edges of the traction hole during the entire travel;

3. The cable length is 1.2 times of the span of the crane and plus 8 meters.

4. Adjust the traction wire rope so that its length is less than the length of the same section of the cable. The traction wire rope is stressed during operation.

5. When the cable diameters are not equal, the cable clamps should be padded with soft rubber so that the outer diameters are basically the same in order to clamp the cables.

6. When laying cables, consider the balanced force on both sides of the cable support plate.

7. When the cable carrier has two or three layers, the requirements are the same.

8. The double washer on the carrier is an adjusting washer. When the guide rail is not suitable, put the washer on the inner side of the fixed plate to adjust the width of the gauge. It is made according to the guide rail specifications 100*68*4.5, 120*74 *5, 140*80*5, 160*88*6. Non-standard pulleys are processed according to drawings.
