Is the site of the tower crane is not, the crane company specializes in the construction site is rented, the price range depends on the length of your period, due to demolition of the problem, I am not a professional, but I am working at the site, only know so much
Q:What is the difference between a tower crane QTZ31.5 and a QTZ40?
Lifting moment, arm length, elevation is not the same ah! Specifically, the maximum lifting weight of QTZ315 is 3 tons, the length of the arm is from 38-42 meters, the elevation is 27-28 meters; the maximum QTZ40 is 4 tons; the length of the arm is 42-48 meters; the elevation is 29-32 meters.
Q:What are the four major moving mechanisms of a tower crane?
Tower crane refers to the fuselage for the tower frame, can walk along the track, a crane equipped with rotary arm. The working space is large, mainly used for the vertical and horizontal transportation of materials and the installation of building components during the building construction. It consists of three parts: metal structure, working mechanism and electrical system.
Q:What are the types of common tower cranes?
(2) according to the transition typeSlewing tower crane: slewing support tower mounted on top of tower. It can be divided into tower cap, rotary tower, top rotating type, upper slewing platform type and rotary column type.The rotary tower crane, slewing tower body is arranged at the bottom, the tower to tower crane chassis rotation.
Q:How to explain and classify the types of tower cranes? What do QTZ80 and Q5510 mean?
This is only the tower crane in different periods of different naming:QTZ---- is the general saying in 80s of last century, Q means steel material (usually Q235), T is tower crane (mostly tower top type), Z indicates heightening method is self lifting,PT------ is the naming method in recent years.

Q:What is the calibration value of a tower crane?
Tower crane calibration value is to benchmark material to be calibrated by standard liquid titration value, calibration to parallel mark three times, take the average value, if the requirement is not strict, error within 3 per thousand, strictly within 1 per thousand.Main performance parameters of tower crane:1. Lifting weight G1. weight G - was the quality of the heavy lift. The unit is t.2. rated lifting weight Gn allows crane lift weights together with the quality of the sum of the spreader.3. maximum weight Gmax - normal work conditions under the crane, the maximum permissible rated lifting weight lifting.Two, range LL - 1. range of level ground when the crane is positioned between the spreader, no-load vertical center line to the center line of the rotary horizontal distance. The unit is m.2. biggest Lmax - crane, jib angle or the minimum car in arm the limit position of the amplitude.3. Lmin minimum amplitude - jib angle or trolley jib in maximum limit position within the range.
