3) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.
The range-change structure drives the dolly to change range on the horizontal arm, with good positioning performance. Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation.
4) The crane has complete set safety devices, which can guarantee the safe and high efficienct operation of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, circumgyrating limiter, etc.
5)The machine has scientific layout and beautiful appearance. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operator.

- Q:Kindly name the companies.
- which okorder / -indian Search engine-quite effective for local searches..
- Q:Calculate the work the crane performs.
- Crane work = weight to be lifted x 6.95 m Weight to be lifted = 2.75x10^3 N + 1.20 m^3 (2.00 x 10^3 kg/m^3) (9.8) = 2750 + 23520 = 26270 Therefore, Crane work = 26270 x 6.95 = 182576.5 J
- Q:im so frustrated because ive tryed everything and im obsessed with this book it would really help if someone could find a way for me to read it for free online. i cant find it at my library.please and thank you:)?
