What is the use of lifting equipment requirements? 110, when one of the following circumstances, the driver should not operate: (1) overloaded or body weight do not hang unclear; (2) the signal is not clear when not suspended; (3) bundle, hanging is not strong or unbalanced may not cause the slide when lifting; (4) is suspended when Ken was not hanging people or float glove; (5) the structure or components affecting safety defect or injury, such as a brake or safety device failure, equipment damage hook nut structure , wire rope damage to be scrapped when not hanging; (6) In case of tension was not hanging unclear buried; and (7) do not hang heavy cable-stayed; (8) the workplace dark, unable to see the venue, hanging objects When not hanging situation and traffic signals; (9) When not hanging heavy in the corners is not padded rope between the bundles; (10) steel (iron) Packaging overfilled when not hanging. 11, crane operation, can not stop the use of limit switches; no reverse braking performance of the crane, except in special emergency situations can not fight anti-brake. 12, shall adjust under load lifting, brake luffing mechanism. 13, when the crane work shall be carried out for inspection. 14, lifting heavy objects from the human head can not pass under the boom strictly prohibited. 15, in the plant lifting goods should take the specified channel. Practice edit one, on both sides of the bridge specified height requirements Longitudinal orbit corresponding to the level remained stable. Before, during and after each lateral leg orbit required level, and strictly control the pitch, three tracks must be parallel. Second, when concrete skew bridge girder installation, bridge machine before, during and after walking round the position of the legs, around the front and rear wheels to be staggered, the distance can be calculated according to the skew angle, so that the legs can be run on the same wheel lateral track (specific issues, please contact the manufacturing units). Third, the bridge machine longitudinal movement to do all the preparatory work is required once in place, it does not allow half-way stop. Fourth, the bridge crane carrying concrete beams longitudinal machine is running, the front leg portion requires hand pull hoist (5t) and fixed sliding track tension and strengthen stability. Fifth, there is the vertical longitudinal install bridge, bridge machine longitudinal displacement taxiing measures have prevented. For example: The iron triangle around the wheel for protection, especially in the legs from the beam end close, pay attention to controlling the shift. Sixth, the bridge machine must be carried out after the assembly hoist crane operation test, the test also used after lifting concrete beams, bridge machine and then run in place to start the installation work. Seven, when the bridge installation work, we should always pay attention to security checks, each installation of a hole must conduct a comprehensive safety inspection, identify problems and timely treatment to stop working in order to continue operations. Mechanical and electrical failures are not allowed to work with. Eight, the installation job allowed overload can not be hanging oblique lifting work. Nine, connecting pin processing material requirements according to design drawings must not be replaced by low steel processing. Ten, five wind over non-job, you must use a solid bridge machine rigging and lifting crane, erecting machine to cut off the power to stop working, to prevent accidents. XI, erecting machine longitudinal position size must be strictly controlled in place to ensure the smooth installation of precast concrete beams in place. Twelve, due to the installation of large bridge bridge machine is special equipment, erecting machine operation must be a clear division of unified command, the operator should set up a full-time, full-time and full-time electrician safety inspectors. Construction organization and have strict measures to ensure construction safety. Of basic conditions are as follows: Commander 1: Familiar bridge structure and lifting work of basic requirements. Firstly familiar with the structure of the bridge machine, assembly procedures, methods of operation and use of the specification requirements, and have some organizational skills, familiar with the command signal, strong sense of responsibility; an electrician: bridging machine can read circuit diagrams and according to FIG. wiring, can quickly troubleshoot problems at work, strong sense of responsibility, business skilled, responsive and responsible persons as erecting machine operation; hydraulic station 1: familiar with the basic knowledge and skills to use and maintenance of the hydraulic system, the correct operation and exclusion of the fault; rigger 3: lifting work with many years of experience, strong sense of responsibility, with certain mechanical knowledge, familiar with the rules and safety regulations crane, serious and responsible, meticulous; Helper 3: a certain cultural knowledge, able-bodied, hard working, willing to delve into the business of youth and culture as an object of use. Thirteen, when the cantilever vertical shift, the upper two-day vehicle must retreat, retreat legs after a car the day before yesterday; legs and rear legs intermediate top high car after the day after tomorrow retreat. Fourth, the top high top high leg the day before the car must retreat at the front legs; acquired vehicle must retreat after a leg. Fifth, the front leg or legs after top high ceiling height, the two-day retreat near the vehicle must be in the legs. Sixteen top front leg high place, you must use special jig locking top high travel segment, in order to avoid prolonged exposure to power jack. XVII hydraulic system, belonging to the two ball-type shut-off valve on the same cylinder, must be closed or opened simultaneously, one must not only open and close another period, otherwise it will cause an accident or even a hydraulic hose burst Cylinder damage; 2, according to the before, during and after the three legs and lifting beam jack of different conditions to determine the relief valve setting value, but the maximum shall not exceed 31MPa. Tuning after locking Nuts, not arbitrarily change the set pressure, too small to work in often overflow, causing the temperature rise can not even work; setting pressure is too large you can not play a role as insurance, damage the elements. Setting specific values ??determined by field technicians; 3, when the oil temperature exceed 70 ℃ when cooling down, when the oil temperature is below 0 ℃ should consider replacing the hydraulic oil temperature; 4, ministries components, such as fault line occurs, immediately stop by trained full-time technician to inspect the repair, the operator can not disassemble; eight, erecting machine must be set up lightning protection devices, be resolved by the use of units. Ninth, carrying capacity crane erecting machine running side beams should meet the relevant requirements must be set free ends stopper. Walking carts box office equipped with special tools (wedge) and warning signs, if due to mechanical, electrical, or misuse caused by runaway carts when walking, walking round the wedge squeezed in between the tracks, so erecting machine can not continue slip. XX vertical shift in the bridge machine or sliding track ends, you must set the stopper to ensure safe shifting bridge machine. XXI before erecting machine work, should be adjusted before, during and after the leg height, longitudinal slope main beam bridge
