1. LX single beam crane techncial explaination
LX type electric single girder suspension crane design and manufacturing follow the”electric single beam suspension cranes” JB2603-94 standard , and CD1 MD1 and other electric hoist supporting the use of a rail operation of light small cranes. General cranes in the 0.5-5T, spam 3-16m, speed 20m/min and 30m/min, if there are special requirments and can be designed and manufactured.
1. Application Scope:
LX-type cranes working grade A3 ~ A5, the working environment -25 ℃ ~ 45 ℃, relative humidity ≤ 85%, suitable for non-flammable, explosive materials and corrosive media conditions work. Melted metal, highly toxic materials used with caution! Because of its compact structure, good rigidity, sensitive operation, low noise, pollution-free, safe and reliable, the crane is widely used in industrial and mining enterprises, warehouses, yard and other places. The crane power supply: AC 380V 50Hz, can also be customized according to customer
2. Main Structure
The basic structure LX crane mainly by the main beam, beams, electric car, electrical, lifting structure. Electric car, driven car and CD1 car universal, has good versatility and interchangeability. General 0.5t span 3 ~ 16m: 1t span less than 12m: 2t span less than or equal to 7.5m can be equipped with beams, but also can be equipped with beams according to user needs. The cross-track varies with crane weight and span. Details are shown in Table 1, Table 2, Table 3. Electrical and mechanical performance and parameters in line with JB834, ZJB80013.3 and JB / T6391.2 related standards.
3. Installation and Debugging:
n order to facilitate the transport, the general situation when leaving the factory Main beams, beams, electric hoist, electric (from) moving the car to decompose the package, the site assembly reassembly.
4.1.1 The main beam and beam assembly Beams on both ends and in the middle of the three shaft holes, the connecting plate inserted into the middle of the beam gap, is the connection plate hole and the middle beam and other holes aligned, fitted shaft II, and then pallets The shaft can be fixed II.
4.1.2 Electric trolley (driven trolley) connected with the beam: The connection between the trolley and the beam is completed by bolts of triangular balance beam axis I, M30X1.5. According to the width of the car track, the use of adjusting pad to adjust the inner edge of the wheel to ensure that the inner edge of the rim along the track 3 ~ 5mm
4.1.3 Electrical and electronic installation After installing the various parts, erection of electrical and electronic circuits in the correct installation. The metal housing of all electrical equipment on the crane must be grounded effectively and the crane track should be permanently used as a ground connection. The total grounding resistance shall not be greater than 4Ω.
4.1.4 hoisting mechanism installation and commissioning Refer to the instructions on the use of electric hoist
4.1.5 cranes on the rail installation accuracy requirements a. Rail span deviation ± 2mm; b. Rail horizontal tilt ≤ 1/1000; c. Track joints deviation: 2 ~ 3mm; d. Track bending deviation: ± 2mm;
The installation should be carried out debugging, the first should be no-load test, lifting and movement of the movement direction is consistent with the button signs; wheel and track clearance is appropriate; brake is reliable; if abnormal adjustments.
Test load 1.25 times the rated load: Test load should be divided 2 to 3 times. The maximum test load, the load should be 100 ~ 200mm from the ground, dangling 10 ~ 15min, after unloading to check whether there is any abnormal site, so repeat more than 3 times, check the actual girder should not less than 0.8s / 1000, but all parts No abnormalities after the dynamic load experiment
