چگونه یک جرثقیل مناسب انتخاب کنیم

Cranes can be the difference between easy construction and tough construction. Many materials have to be hoisted up the building being constructed for construction to go on smoothly. While this is true, a crane business will still have to know the best cranes for each construction to avoid disappointing its clients. For this, businesses must take time to learn the ropes of their venture before making any investments.

Cranes: market share and demand

The global market size of cranes was $36.36 billion in 2021. This was after a 2.7% growth from the previous year. The global market for cranes is shifting to promoting renting of cranes instead of buying. In addition to this, major players seek to develop stronger cranes that can bear more load to profit from the growth expected in the industry. There are also high investments in the industry to develop technologies that enable smart factories in the manufacturing sector. 

Factors to consider when buying a crane

This segment will focus on essential tips that every business should consider before purchasing.

Load to be carried

Each crane is suitable for a particular weight. The truck-mounted crane can hold a maximum load of 25 T. The jib crane can carry loads of up to 15 T, while the tower crane can lift 18 T.

Terrain of the site

Rough terrain will require a rough terrain crane, while an indoor site will require an overhead or jib crane. The tower crane is suitable for outdoor sites as well. Businesses should consider the terrain of the site before making a purchase.

Access to the project site

Some cranes are mobile and can go to any site, while others are huge and cannot access all sites. Due to its size, the tower crane will not be suitable for small and inaccessible project sites. A truck-mounted crane or mobile crane would be better.

Cost of the crane

Cranes are very costly due to the technology involved and their convenience. The tower crane costs $ 100,000- $ 200,000, while the jib crane costs between $ 3000- $ 5000. An overhead crane will cost between $ 10,000- $ 50,000. Businesses should consider the amount they are budgeting for a crane before purchasing. 

ارتفاع کار

The jib crane can reach 230 فوت, while the tower crane is suitable for buildings as tall as 265 فوت. The overhead crane will hoist loads up to 80-100 فوت high. Before settling on a crane, prospecting businesses need to know the heights they will be working with to make an informed decision.

Target market for cranes

Cranes are expected to grow at a CAGR of 4.5% to $49.64 billion by 2028. This is likely to result from the growth in the industrial sector globally and investments by governments and private entities in the construction sector. For example, the Asian and Latin American markets are placing a massive demand for machines capable of lifting 500 t and beyond. The Asia Pacific region will witness the most significant growth. China has commissioned 27 infrastructure projects worth $219.43 billion. The North American region is also expected to grow due to investments in the mining industry.
