The technical parameters of small gantry crane are revealed: the perfect combination of lifting weight, span and lifting height

Lifting weight:
Generally, the lifting weight of small gantry cranes is between 1 ton and 10 tons, such as 1 ton, 2 tons, 3 tons, 5 tons, 8 tons, 10 tons and other different specifications.
Span:
The span is usually about 3 meters to 20 meters. Common spans are 4 meters, 6 meters, 8 meters, 10 meters, 12 meters, 15 meters, 18 meters, 20 meters, etc., the specific span needs to be determined according to the use of the site and operation needs.
Lifting height:
The lifting height is generally in the range of 2 meters to 18 meters. The common lifting height is 3 meters, 5 meters, 6 meters, 8 meters, 9 meters, 10 meters, 12 meters, 15 meters, etc., special requirements can also be customized higher or lower lifting height.
Job level:
Small gantry crane work level is usually A3, for some slightly higher requirements of the work scene may reach A4 level, more demanding operations may require a higher level of work, but in the small gantry crane is more rare.
Cantilever length:
The cantilever length usually does not exceed 4 meters. Some small gantry cranes may not need a cantilever, and there is a cantilever demand, the cantilever length is generally between 1 meter and 3 meters, the specific length is determined according to the actual use.
Running speed:
Truck running speed: generally between 10 m/min to 50 m/min, such as 20 m/min, 30 m/min, 40 m/min, etc., the speed of the speed will affect the moving efficiency of the crane on the track.
Car running speed: usually around 15 meters/min to 40 meters/min, such as 20 meters/min, 25 meters/min, 35 meters/min, etc., the car running speed determines the moving speed of the lifting mechanism on the main beam.
Lifting speed: Lifting speed varies according to the lifting weight, the lifting speed of small gantry cranes is generally between 3 meters/min and 10 meters/min, for example, for a small gantry crane of about 3 tons, the lifting speed may be about 5 meters/min; For a small gantry crane of 1 ton, the lifting speed may be about 8 meters/minute.
Track:
Track type: There are light rail and heavy rail, small gantry cranes generally use light rail more, but if the operating environment has high requirements for carrying capacity and stability, heavy rail may also be used.
Track size: The type and size of the track need to be selected according to the lifting weight of the crane, span and other parameters, common light rail models are 15kg/m, 22kg/m, 30kg/m, etc., heavy rail models are 38kg/m, 43kg/m, 50kg/m and so on.
Overall dimensions:
Height: The overall height of the small gantry crane (from the ground to the top of the main beam) is generally between 3 meters and 10 meters, depending on the lifting height and the height of the leg.
Width: The width of the gantry frame (the distance between the two legs) is usually about 2 meters to 6 meters, in order to adapt to different working Spaces and cargo sizes.
Motor power:
Motor power: generally between 2 kW and 10 kW, the specific power is determined according to the span of the crane, operating speed and carrying capacity and other factors.
Car motor power: usually around 1 kW to 5 kW, lifting motor power is between 3 kW to 15 kW, also related to lifting weight, lifting speed and other factors.
