The Best Green Business Ideas (You Can Start Right Now)

It’s officially the second month into the New Year. And, you may have set aside a goal to start a new business or explore your hidden side hustle talents. Yet you may have also set a goal for yourself to work towards sustainability. Instead of throwing everything in the trash, you could compost some items and recycle others — seems to be the best for saving the earth. And, it makes you feel that much better when you’re helping the world one recycling bin at a time.

When it comes to starting that new business idea or side hustle, how will these efforts correspond with sustainability? Would you rather use electronics in the office vs paper? Would you ensure that all employers would recycle and compost as much as they can? And the products you produce; will they be environmentally friendly?

It’s common to think about these things in the beginning stages. And, it also comes as no surprise that many employees nowadays value companies that have good sustainability practices. For instance, CSR (corporate social responsibility), is a scale that many employees will seek out before applying for a job or signing over their offer letter.

To ensure your business practices align with your own beliefs and values, not to mention those of your employees, you may be brainstorming eco-friendly business ideas now. To help you and your entrepreneurial soul, we brainstormed a few business and side hustle ideas below. Once you choose an idea, be sure to cover all your bases (legally) to ensure you and your business idea are on the track to success.

From manufacturing to shipbuilding to towering city skylines, just about every sector of the construction industry would be nothing without the contributions of crane technology. The simple lever-and-pulley robotics of a tower crane serves as a practical way of assembling massive structures and lifting upwards of 40,000 pounds of material at once.

But have you ever driven by a bustling construction site and wondered how cranes work? The vast abilities of tower cranes often go overlooked by those not working in construction, but it’s important to understand the functions and self-sufficient nature of these powerful machines.

Structure of a Tower Crane

Though their technology may be conceptually simple, tower cranes have a complex makeup of moving parts that allow for maximum performance when lifting heavy loads. The crane’s tower, which extends upward from the base, remains stable due to a solid concrete foundation at the base. On the upper end sits a rotating device known as a turntable, which allows for a 360-degree view from the operator’s cab at the crane’s apex.

The parts of the crane that do the actual lifting are a trolley and hook block, which span a long, arm-like jib that extends from the top of the crane. This mechanism allows the crane to vertically lift and lower loads of materials. The trolley and hook block harness movement from the crane’s main winch, which is a motorized component that sits behind the operator’s cab. To balance the mass amounts of weights a tower crane handles, counterweights hang from a counterjib that stretches behind the operator cab.

How Are Tower Cranes Built?

There is only one piece of machinery that could properly assemble something as unique as a crane: itself!

Builders start by using mobile cranes meant for smaller-scale structures (shorter buildings, machinery, etc.) to lay the concrete foundation and assemble several of the tower crane’s parts, such as the jib, operator’s crane, and counterjib. Then, the mobile crane begins lifting sections of the tower into place. Once the tower reaches a sufficient length, builders use a hydraulic jack and what already exists of the tower crane to assemble the rest of its own tower.

This unique construction process is why those in the construction industry consider tower cranes to be such self-sustaining and powerful tools. Several of the most famous buildings in the urban world, including such giants as the One World Trade Center in New York City, would not have been possible without this technological innovation. Standing among some of the world’s most impressive cranes, they will remain crucial tools in urban development.

So next time you find yourself in the city and pass by a massive tower crane, always remember what a fascinating piece of equipment is staring right back at you. Knowing how they function, as well as their practical applications to building and machinery, will be essential for anyone entering the field of construction or robotics.
