Crane Buffer
During
crane or trolley running, the brakes or limit switches may suddenly break down.
Due to inertia, the vehicle will continue in the state of motion until running
into the end stop preset at both ends of its runway track. The aim of adding a
crane buffer to the contact area between the end stop and trolley or crane is
to absorb the majority of energy produced in an impact shock. Following is a
list of two buffer forms most commonly in use today.
Polyurethane Buffer
Advantages
Lightweight
design available at a competitive price
Ease
of maintenance and repair
Resistant
to corrosion, impact and stress
Generate
neither noise nor sparks during operation, thus suitable for use in explosive
atmosphere.
Technical
Features
Crane
buffer density:0.55-0.65
Shore
hardness:50-65
Compressive
Strength(50% compression):12-15kg/cm2
Operating
Temperature:-30-60 degrees
Hydraulic
Buffer
Advantages
With
the increase in the extent of compression, the number of holes that allow fluid
to pass through will be reduced to ensure a uniform speed at which the
buffering process is carried out.
Despite
its compact design, this series of crane buffer is able to absorb a large
amount of energy.
This
hydraulic buffer enables a maximum deceleration of the running crane or trolley
while coming in a minimum size. For cranes with high mass or speed exceeding
2m/s, the buffer just provides a most suitable solution.
Technical
Features
Absorb
80% to 100% of energy produced in impact shock
Angle
of deflection after collision is controlled within the range between 0 and 1
Operating
temperature:-25~80 degrees

Under the background of the rapid development of the global footwear industry, China's footwear industry can be described as an indispensable main force. In just a dozen years, China has become the world's largest footwear producer and exporter. Jinjiang, known as the “Chinese shoe capitalâ€, is the mainstay of China’s footwear industry. It not only has superb production equipment and a complete shoe industry Chain, but also is a gathering place for a large number of brand-name companies and has mature footwear. market. However, with the advent of the post-crisis era, the narrowing of the globalization gap, and anti-dumping and other trade barriers in major market countries, the shoe and clothing industry in Jinjiang and even the entire country is facing enormous challenges. Market transfer and industrial transformation and upgrading have been The agenda. These have greatly promoted the rise and development of the local footwear industry e-commerce.
The rapid development of the footwear industry has promoted the development of finished shoes and shoe testing equipment. A number of manufacturers of footwear testing instruments have emerged along the coast of Guangdong and Jiangsu and Zhejiang, and the procurement of equipment has expanded from the shoe manufacturer to the government inspection department. Universities and colleges and universities have effectively guaranteed the quality of the Chinese footwear industry.
With the continuous development and improvement of international Internet technology, it has greatly promoted the development of global economic integration. The rise and application of e-commerce has also significantly promoted the development and advancement of various industries. According to statistics, 60% of small enterprises, 80% of medium-sized enterprises, and 90% of large enterprises in developed countries in Europe and America began to rely on networking to conduct business activities. In the current rise and application of e-commerce, not only the government attaches great importance to it, but it is also a breakthrough point for enterprises seeking a turning point in the post-crisis era.
