Views: 1    

 A tower, purchase (rent)
 
1. The tower to purchase must have effective production license of professional manufacturers to buy, and the manufacturers to provide the quality certificate, high strength bolt connection ZhiBaoShu, lifting rope ZhiBaoShu and other general parts ZhiBaoShu tower and the instruction for use technology material.
 
2. Rent external tower: (1) must sign a written lease agreement, the agreement between the parties must build official seal unit, do not allow to private, soho rent; (2) the machine must be good in tower, without any privately behavior modification, safety device should be complete, life not more than five years; (3) the lessor must provide crane production license, the factory certificate (the original) tower and use the description and the competent department qualified report.
 
3. Purchase second-hand tower shall determine: (1) life not more than three years; (2) the safety device is complete, the machine condition good; (3) the certificate (the original) and relevant technical data is complete; (4) manufacturers over the close or not carry industry.
