Inspection Standard of Mobile Scissor Lift


Inspection standard of mobile scissor lift has been replaced by JB/T9229-2013 in 2014year. This standard was released on Dec. 31
st 2013, and carried out from July 1st 2014. MORN GROUP is keeping update and improvement on the mobile man lift, also the stationary scissor lift. For a clear understanding to customers, here introduce some rules of scissor lift.

A. Normal standard:

a. Raw material used should be with quality certificate and technical feature not less than original design requirements.
b. Rated capacity should be shown clearly on mobile scissor lift.
c. To the mobile elevated platform which with external work platform, allowed load capacity and relative work condition should be introduced clearly on specification.

B. Work condition to mobile scissor lift

a. Ground floor should be solid and flat. No sag allowed when working.
b. Work temperature: --20~40
c. Ambient humidity: 90% when temperature is 20
d. Elevation should be less than 1000m.
e. Wind speed12.5m/s
f. Work voltage: ±10

C. Butt weld on scissor structure, connection between support beam, chassis and railway should be applied to of GB/T 3323-2005.

D. To performance requirements of mobile scissor lift

a. Rising speed/falling speed should not be more than 0.4m/s; rotating speed0.7m/s. To the trailer scissor lift when rising, travel speed should not be more than 0.4m/s. When closed, travel speed 0.7m/s.
b. No unbalancing loading allowed. Carry ability of work platform can bear 1.33times than rated capacity. Deformation of stress components are not allowed when over 30times lifting.

E. Deflection of mobile scissor lift should not be more than 0.5% of maximum.

F. Stability of whole machine should be applied to 5.2.4 of GB 25849-2010.

G. Guardrail height should not be less than 1.1m. There is no middle bar. Space between middle bar should be less than 0.55m.

H. Hydraulic system conforms with GB/T 3766. Hydraulic components apply to GB/T 7935.

Every mobile scissor lift will be tested and inspected strictly before delivery.

NO.
