Tripod ladders are widely used by gardeners
and nurserymen. It`s ideal for orchard work, both for picking and pruning.
The tripod design makes it very stable and practical.
It's made of aluminum alloy, all connection
parts are firmly welded processing, and the foot is with claws and anti-slip.
Max load capacity can be 100kg to 150kg.

In 2012, the United States accounted for 10% of new energy generation in 2012, and 25% in 2025. In 2020, the total installed capacity of photovoltaics is 7GW (879MW in 2007); TC tax rebate: 30% of the investment cost, the tax rebate for residents is not more than 2,000. US Dollar; Planning after 2009: 1. Investment tax credit for commercial projects is extended for 8 years, investment tax reduction for residential PV projects is extended for 2 years; 2. Tax reduction for US$2,000 per household PV project is cancelled, 2009 2 A new subsidy policy was introduced on the 17th, with about $80 billion in government spending, loan guarantees and tax incentives for the energy sector. The United States was the first country to conduct photovoltaic grid-connected power generation. Since 1974, it has successively promulgated relevant laws and regulations to promote sustainable energy development. The photovoltaic industry has been included in the development priority area, and has successively issued the Solar Energy Research and Development Act, the Solar PV Research and Development Model Act. The Energy Tax Law, the Tax Reform Law and the Energy Policy Act, etc., support the commercial development of photovoltaic technology and industry in terms of development goals, capital, and research and development. The US Department of Energy proposed a plan to gradually improve green power development, and formulated a roadmap for technological development of solar power generation. Among them, solar photovoltaic power generation is expected to account for about 15% of the increase in power generation capacity in the United States by 2020, with a cumulative installed capacity of 20 million kilowatts. Maintain the world's leading position in the development and manufacturing level of photovoltaic power generation technology in the United States. In the early 1980s, the implementation of the PVUSA program, the application plan for the scale of photovoltaic power generation public power; in 1996, with the support of the US Department of Energy, another project called “PV Building Plan†was launched with an investment of US$2 billion. In the same year, California created a $540 million public benefit fund to support the development of renewable energy. The Renewables Buy-Down Program provides $3 per watt of subsidies for solar systems with installed capacity, so that the discount level drops by 20 cents/watt every six months. The California Solar Energy Industry Association (CalSEIA) has recently proposed to expand the program, while other states are following the example of California and trying new programs: 20 states have discounts supported by government or public utilities; other 17 states, including In California, renewable portfolio standards have been established to increase the use of renewable energy; Arizona in the southwestern United States and Nevada in the western inland retain some of the asset standards for solar energy. In 2006, the California government invested 3 billion US dollars to support the development of the photovoltaic industry, implementing a fixed-net tariff of 50 cents, and reducing the support price by 20% every year, which greatly promoted the industrialization of photovoltaic power generation. In June 1997, President Clinton announced the implementation of the “Million Solar Roof†plan and the “Net Flow Meter†system. Each photovoltaic roof will have a 3-5KW photovoltaic grid-connected power generation system. When there is a sun, the house will supply power to the grid and the meter will be reversed. When there is no sun, the power grid supplies electricity to the home, and the meter is turning forward. You only need to pay the “net electricity fee†every month. It is planned to install 1 million sets of solar roofs by 2010, mainly solar photovoltaic power generation systems and solar thermal utilization systems, further pushing the integration of photovoltaic power generation buildings to a climax. The proposal of this plan is determined by the trend of social development, and is also the result of long-term efforts of the US staff dedicated to solar energy development and research. The importance and support of the US federal and state governments for sustainable energy is also an important driving force for the active restructuring and optimism of the US industry. For decades, the federal government has focused on sustainable energy as one of the key areas determining the future international competitiveness of the United States. In addition to government funding for research and development, a number of technical commercialization demonstration projects have been established. In order to encourage the development of sustainable energy industries, state governments have introduced industrial tax incentives to attract sustainable energy industries to invest in the state. There are 12 states in the United States that implement renewable energy quotas, which are generally supported by renewable energy companies and the public, and Texas is the most successful. In 1998, the Clinton Administration's Comprehensive Electricity Competition Regulations established a renewable energy letter of credit that can be traded and deposited in banks to increase the flexibility and efficiency of the quota system. The value of the letter of credit is 1.5 cents/kWh. In addition, there are six states in the United States that implement public benefit fund policies. However, the specific practices and charging standards vary from state to state. This has proven to be an effective means of raising funds for renewable energy generation. Taxation and subsidy policies in US states have played a crucial role in the rapid growth of the grid-connected PV market. Especially in California, the emergence of the 2000-2001 energy crisis has prompted local governments to accelerate their support for new energy sources. Encouraged by various local stimulus policies such as the local government buy down, Pioneer program, and Water and Power PV program, California's grid-connected PV building installation capacity reached 15.3MW in 2002, accounting for 68% of the entire grid-connected market. The United States is a veritable "solar city." In addition, since the 1990s, the US solar and sustainable energy industries have begun to plan for restructuring. The formation of the US sustainable energy industry restructuring plan is caused by the rapid development of technology, the further improvement of the degree of market internationalization, and the intensification of corporate mergers. The program is led by the American Association of Sustainable Industries and consulting companies, and has conducted extensive and active negotiations to reach consensus within the industry. The program hopes to increase the scale and competitiveness of the US sustainable energy industry through an optimal combination of resources, including talent, information, materials, markets, technology, sales networks and funding.
