Wholesale Outdoor Heavy Duty 35 Ton Double Girder Gantry Crane
Wholesale Outdoor Heavy Duty 35 Ton Double Girder Gantry Crane also belongs to the category of cranes, its essence is the gantry crane. The main components of this kind of lifting machinery are main beam structure, supporting legs, walking beam, walking structure, electrical appliances, ladder cab and other parts. The main structure of gantry crane is mainly plate welded box structure, the main beam and supporting leg can be divided into several sections, the joints are mainly connected through the joint plate and refined high-strength bolts. Gantry crane is characterized by convenient transportation, flexible assembling and fast assembling speed.
Wholesale Outdoor Heavy Duty 35 Ton Double Girder Gantry Crane manufacturer is the first inspection beam, every ten days inspection. Check whether the joint weld has open welding cracks, whether the main beam has residual deformation and instability, if found, the application should be suspended, to be corrected.
Wire rope should be two weeks time to slide once, before lubrication should eradicate grime. As usual, any wire rope twist, found cracking over 6 should be scrapped immediately. (daily pre-shift inspection) should be updated when the wheel is worn over 15% of the original thickness or there is cracking. The accelerator can not be short of oil, should be regularly switched, found abnormal and noise timely maintenance. The brake of lifting organization is checked before each use, and the brake of running organization is checked once a day before use. Vice - improvement USES electric hoist, due to the use of improper operation and lead to loose parts, metal fatigue and other causes of attack, special emphasis on weekly inspection, and careful record.
This task by longmen crane manufacturer professional electrician as the end, and fill in the electrician maintenance maintenance record. Adhere to clean electrical equipment, such as resistor, control screen, touch, etc. Eradicate the external dust, grime, prevent leakage of electricity, breakdown short circuit and other bad scene attack. Check by electrician everyday, fill in duty record. Often investigate the motor rotor sliding line, brush touch can be excellent. Return sound of motor, electromagnet, breaker, electromagnetic switch, etc. When the application condition is bad, the insulation resistance of motor and wire should be measured regularly. Longmen crane manufacturers attention: conductive wire, support insulation and various housing grounding. The clip rail of electric hoist and each component join bolt can have loose in the effect, so it is necessary to inspect each part carefully once a week.
1. Wholesale Outdoor Heavy Duty 35 Ton Double Girder Gantry Crane girder is mostly transported to the site by sections. Perform docking assembly on site. Check the geometry after assembly and welding. It is found that there is a difference between mid-span camber and cantilever camber, so the values of mid-span camber and cantilever camber should be adjusted immediately.
2. The Wholesale Outdoor Heavy Duty 35 Ton Double Girder Gantry Crane parts are too long to enter the site due to road problems. This happens all the time. First of all, a transportation plan should be made. Fully consider the emergence of this phenomenon of emergency countermeasures. The usual method is to prepare a truck crane in advance. Travelling in a transport convoy. When it is difficult for the car train to turn, the truck crane is used to lift the combination of the crane's extra-long parts and the trailer and the tractor to make the steering.
3.The crane girder in the lifting test found. The actual lifting weight is greater than the value in the installation scheme. This phenomenon often appears in the installation site. The reasons are generally: negative deviation of budget weight; The lifting load is increased according to the actual situation on site. This phenomenon should be fully considered in the formulation of the installation scheme. So the crane layout of its position to put the maximum safety factor.
4. After the installation of Wholesale Outdoor Heavy Duty 35 Ton Double Girder Gantry Crane, it is found that the Angle of connecting flange between the supporting leg and the trolley beam is wrong. It has to be adjusted. Support leg of the support or cable wind rope is not removed. The joint weld of flange plate and supporting leg is cut. Adjust the Angle before welding.
