How to choose telescopic mast?
1. which type of mast do you like? manual, electric or pneumatic
2. your expected close height and extended height of the mast
3. what will be mounted onto the top of the mast and its estimate weight
Give us the above information, we can customize the telescopic mast for you.
What's the discrepancy of manual, electric and pneumatic mast?
Manual telescopic mast is used for the circumstances without power supply, the payload is about 5KG to 30KG depends on the mast extended height and tube diameters.
Electric telescopic mast is lifted by power supply, the load capacity is similar to the manual telescopic mast. When the power is no available, it can be lifted by manual hand crank.
Pneumatic telescopic mast top payload is much higher then the electric and manual mast. It needs air pump/compressor to elevate, it may not work in the temperature under 45 degree. Hollow mast, with less weight itself, max 400KG payload, but higher cost.
