Uses of hammerhead tower crane
Heavy load-lifting plays a vital role in any transporting operation .the mechanism should be fast and efficient and also should provide safety during operations.
Hammerhead Tower Crane is used to lift effortlessly heavy loads. To operate a machine a qualified person is required who has much knowledge in operating .since many accidents happens around crane lifting because of improper action.
There are two types of crane category: stationery and portable, there are types of crane of different sizes and shapes.
The most common crane used is a portable crane. Portable crane truck hire mounted crane and it is also called a portable pickup truck crane. This crane truck hire has standard crane features that can carry loads ranging from 15 tons to even 1000 tons. This crane truck hire can transport cargo from allocation to another by itself on the road. But this crane truck hire has a great improvement over the stationary cranes.
What is a hammerhead tower crane?
A hammerhead tower crane is one of the most common types of cranes used around the world. They are especially reliable for precise, accurate handling of a wide variety of heavy materials. The way they can be adapted to work well for any job site and any type or volume of material being transported is what makes a hammerhead tower crane such a versatile workhorse.
The pull rod on the hammerhead connects the jib boom with a balance arm and form triangle support, which ensure the overall balance of the horizontal direction of the hammerhead tower crane for sale. The hammerhead connects the tower body and slewing bearing, which keep the balance of all the tower body. Therefore, when the machine turns, there will not be an excessive distortion of the mast section.
Tower cranes are widely used for lifting operations in the construction industry. Statistics show that tower cranes contribute to quite a number of serious accidents. Property damage and bodily injuries can be avoided if they are properly used.
A counterweight is added to the opposite end of the articulated jib to counteract the weight that the crane will be lifting. In such Cranes, the armrests on a thrust bearing over tower structure which takes up all the load. The arm is initially balanced by using the counterweights at the other end of the arm.
The maximum wind speed for safe compact crane use is 22 miles per hour/ 36 kilometers per hour / 10 meters per second
The maximum value for this is generally 20 m/s (45 mph), but this amount can vary. A review of in-service wind speeds by the Tower Crane Interest Group concluded that the maximum recommended wind speed for towers in the UK should be 18.5 m/s
