Some users in order single-girder crane , the band is an electric hoist, but after put into production discovered that a hoist can not meet production needs, wants to install an electric hoist, but because not secretly install electric hoist , need Only qualified manufacturers and workers with installation permits can work. The installation of electric hoists on single-beam bridge cranes belongs to the scope of crane transformation. Before construction, it is necessary to formulate a transformation plan and perform special equipment notification procedures. After the transformation, it must pass the supervision and inspection of the Mechanical and Electrical Special Equipment Safety Inspection Institute before it can be put into operation.
1. Anti-overload requirements.
Overload limiters should be set on both electric hoists. When two electric hoists are linked, it is necessary to prevent the total hoisting load and the danger of overloading each electric hoist during combined lifting.
2. Anti-collision safety requirements
The electric hoist can be equipped with an anti-collision safety device to prevent collisions between two electric hoists, and when the electric hoist is linked, when the front electric hoist moves forward and the rear electric hoist moves backward, the two trolley operating mechanisms should Stop at the same time.
3. Linkage conversion
The two electric hoists can be operated in linkage or independently, and a single-action/linkage switch should be set to realize the single-action/linkage conversion function and realize the protection function under corresponding working conditions.
Reconstruction of cranes is a common thing. When remodeling cranes, a qualified manufacturer should be selected for the transformation operation to avoid potential safety hazards during the transformation process, which will cause serious impact and harm on enterprise production and personnel safety.
Our editor recommends that when ordering a crane, you should choose the appropriate type of lifting equipment according to your own needs, and you should not choose equipment that does not suit your own for the sake of cheapness.
