Main Technical Parameters of Overhead Cranes
The main technical parameters of the overhead crane are lifting capacity, span, lifting height, running speed, lifting speed, work duty, etc.
Lifting capacity
Lifting capacity, also known as rated lifting weight, refers to the maximum allowable lifting capacity of the crane. There are various lifting capacities for you to choose from, including 5t, 10t (single hook), 15t/3t, 20t/5t, 30t/5t, 50t/10t, 75t/20t, 100t/20t, 125t/20t, 150t/30t, 200t/30t, 250t/ 30t (double hook), etc. Generally, overhead cranes can be divided into three levels according to the lifting capacity: small and light duty overhead cranes (1~10t), medium overhead cranes (10~50t), heavy duty overhead cranes (above 50t).
Span
The span of the overhead crane refers to the distance between the centerlines of the wheels at both ends of the main beam of the crane, that is, the distance between the centerlines of the rails of the crane. Overhead crane spans are 10.5, 13.5, 16.5, 19.5, 22.5, 25.5, 28.5, 31.5m, etc. for you to choose from.
Lifting height
Lifting height refers to the distance between the upper limit position and the lower limit position of a crane’s hook or grasping device, such as a grab bucket or an electromagnetic chuck. The common lifting heights of overhead cranes are 12, 16, 12/14, 12/18, 16/18, 19/21, 20/22, 21/23, 22/26, 24 /26m.
Running speed
Running speed refers to the speed of the moving mechanisms of the crane and the trolley when the motor runs at rated speed.
Lifting speed
Lifting speed refers to the speed of weight lifting when the motor is running at rated speed. Generally, the lifting speed does not exceed 30m/min, depending on the type and weight of load or material and lifting requirements.
The lifting speed also includes the empty hook speed, which can shorten the non-productive time. The empty hook speed can be up to twice the rated lifting speed. In addition, there is low speed when the heavy object approaches the ground, called the low landing speed, which can ensure personal safety and cargo safety, and its speed is generally 4 ~ 6 m/min.
Duty cycle
Duty cycle or service classification can be determined by load spectrum and average daily operating time. It can be divided into four types: light duty, medium, heavy duty and extra heavy. Selecting the right duty cycle or service classification is critical to ensuring that the crane components are durable enough to withstand the load and usage requirements.
