Bigger is better, and a larger crane will save you time and money because you can move more material at once.
Since most material carts have a maximum capacity of 2,000 pounds, moving more material than recommended is not safe and can damage the roof. Most roofing materials are packaged at 2,200 pounds or less. Although a large crane may be capable of lifting 5,000 pounds at once, the material still has to be broken down to 2,000 pounds or less once on the roof. Paus Sky Worker is capable of lifting up to 2,000 pounds to 40 or 50 feet and can reach places bigger cranes cannot.
Renting is always more cost effective.
Renting could cost more than buying if you need regular access to a crane. Once you have paid for the crane, its use is pure profit.
There can also be a waiting period to rent certain cranes at busy construction times of the year. Owning a crane gives you access whenever needed, allowing you to plan jobs much more efficiently. You control when and where your crane is without extra charges.
Plus, renting different types of cranes requires time and money spent on training your crane operators – or paying extra to have the rental company provide skilled operators. With proper maintenance, new PTK-31 cranes last an average of 20 years and have residual value. You could sell it or trade it in whenever you want to upgrade to a new model.
