The difference between the derrick and the construction elevator?
They're the same. HAULOTTE answer for you
You want the picture to still want to explain, the words to go to baidu search all can. The derrick is not to be multiplied by the person, the setting height is not more than 30 meters, now most of the place begin to phase out the use of the derrick, because the safety coefficient is low. The construction elevator can carry cargo, set up a height of 150 meters, and can carry a weight of 1-3 tons
Derrick is with the hoist rope hoisting, referred to as goods for SSB100 type, with construction lifter model does not allow the manned, deadweight is one tons, construction lifter is said cargo amphibious ladder, with gear and rack driving, weight is 2 tons, you can have a look at the GB/T 10054-2005, the construction lifter, with clear rules.
