Q: Detection and quality standard of bridge erecting machine: Double cantilever girder erecting machineBridge construction machinery, the use of the Soviet Union earlier. In 1948 the introduction of the front and rear arm with steel beam, lifting weight of 45 tons and 80 tons of two kinds. In 50s, the two arms to the framework, lifting to 130 tons.

Q: How much is a bridging machine: The preliminary estimate can be calculated according to the weight of steel structure. Unit price of about 1.5~2 yuan / ton.

Q: Bridging machine rack in the front beam can beam block and padded timbers, whether there is stress between them.: The general will stagger the stop position, directly to the top surface of the support beam

Q: Weight of 120 ton bridging machine: 0.65m/min (40 m and 120 tons beam) - 0.75m/min (30 m and 100 tons beam) 0.95m/min (30 m, 80 tons beam), the vertical speed of the crane: 6.6m/min 7, crane cross.

Q: What are the conventional lifting equipment? Bridge erecting machine is a kind of lifting equipment: Belongs to the non-standard crane, exactly belong to special equipment

Q: How many special operators do you need to build a bridge machine? What kind of special operations personnel should be held?: Other construction workers 10~20 ranging. See the specific operation of the type of equipment.

Q: 2700t bridging machine assembly summary how to write: So you should write a few points:1, your job and work on the understanding of the 2, specifically what you do3, how do you work hard, what is your brain to solve. Even if there is nothing, but also to write some difficult questions, how do you solve the problem4, in the future work you need to improve what ability or enrich what knowledge5, superiors like active work.

Q: I would like to know the working principle of JQ IV 160t/40m bridging machine?: Working principle: the front assembly, the central assembly and the longitudinal moving flat car assembly are equipped with rotary 0-45 angle of the rotating support to meet the requirements of the bridge girder oblique beam. When the bridge erecting machine is inclined to set up, it is necessary to pre install the central cross beam and the middle part of the roll, the front cross beam and the front roll, the trolley beam and the crane in the angle of oblique installation.

Q: Bridging machine which consists of four parts: D, brake system - including parking brake, working brake;E, steering system - including the upper and lower hinge body, steering cylinder and the corresponding operating mechanism;F, the work system - including the bucket, the big arm, the rocker arm, the connecting rod and the correlation pin shaft;G, hydraulic system, including hydraulic system, hydraulic system, hydraulic system, hydraulic system, hydraulic system, hydraulic system, cooling system, lubrication system;
