All equipment and product should have performance inspection before ex works; the tenderer should provide the following: ex works product certificate

6、of inspection, approved certificate for product, product instruction, packing list, and list of accessories and spare parts.3. All the electric driving device of the hoisting equipment should be complete matched by the hoisting equipment manufacturer, to make it form complete hoisting equipment. Mat

7、erial to be submittedThe tenderer should submit the following information, but not limited to the following: (1) The concerned technical data and electric schematic diagram of electric machine and electricity; (2) Installation instruction, equipment operation and service manual; (3) Qualification ce

8、rtificate of manufacturer and achievement; (4) Bidding technicality description (design, structure, material etc.) and sample editing; (5) Manufacturing and quality assurance measures; (6) Debugging and detection requirement before test-run; (7) Submitting five users certificates of successful opera

9、tion running domestically in recent five years; (8) The hoisting equipment manufacturing license issued by Domestic Labor Department; Basic requirements1. Reference standardsThe design, manufacture, inspection, packaging, transportation and installation process of the product should be consistent wi

10、th ISO, IEC international standards and the equivalent standards such as GB, JB, JIS, DIN, ANCI, etc. (These standards should be the updated standards that are not be invalidated) ) 2. Other technical requirements (1)The hoisting equipment supplied by the tenderer should include the electric mono-sp

11、ar suspension hoist crane, electrical block and the concerned accessories for connection.(2)The complete electric motor and the speed reducer should be supplied by the manufacturer in the form of complete and matching.(3)The equipment failure free operation time should not be less than 10,000 hours;

12、 the electric apparatus service life should not be less than 3 years, the speed reducer and bearing service life should be 10 years, the coating service should be over 5 years; the complete machine service life should be more than 25 years.(4)Anti-corrosion of equipment: the surface de-rusting grade

13、 of all carbon steel components should comply with the Sa2.5 grade standard stipulated in GB8923-88(5)The manufacturer should provide 1 set special tools and spare parts for the equipment installation and maintenance.(6)Nameplate and LabelIt should be fastened for All equipment with the stainless st

14、eel nameplate of following technical specification contents: Number, Model, Power, main technical parameter, weight, manufacturer, date of manufacture etc.(7)Material and ProcessAll materials must be the high quality material with indicated grade and species, these should be the newest material used

15、 by the manufacturer, not the rejected into disuse, and the manufacturing process should be the contemporary optimality criteria.(8)The tenderer should be in charge to guide the installation of the equipment, to accomplish the debugging work of the equipment within the period stipulated by the const

16、ruction party. Structural requirements(1)Traveling Mechanism BodyThe body is rigid structure, forbidden any abnormal bend.The traveling mechanism driving relies on the electric motor through speed reducer to drive the trolleys driving shaft.The mono-spar body should have a roller stabilizer, to prev

17、ent the traveling mechanism from incline during operation.The material of the traveling mechanism wheel is steel rolling or forged steel heat treated; the hardness of the tread of the wheel should be at 200 Brinell at least.After refining process and burnishing, the wheel axle material can assembly

18、the inner bearing washer.When using the rotation axis, the wheel should install the contractor and key, or install the key only.All the gears are spiral tooth, straight tooth or herringbone tooth, the gear wheel is manufactured of steel rolling or cast iron, and process it to be 20° pressure in

19、termeshing angle.The bearing is the radial and thrust, double bank, angular contact ball bearing, or the double bank thrust type roller bearing. Before installation the bearing should be lubrication and sealing; the brake of the traveling mechanism should be assembled according to the stipulated wor
