Henan Mine Crane 5 Ton Single Girder Overhead Crane
LDA Single Girder Overhead Crane has two operational methods, ground or operational room which has open model and closed model and can be installed on left or right side according to the practical situation. And the direction of entering the gate has two forms, sideway and ends in order to satisfy the users' Choice users' different conditions.
Features:
1) Reasonable structure
2) Favorable performance
3) Smooth starting and stopping
4) Safe and reliable traveling
5) Low noise, commodious cabin and good view
6) Convenient maintenance, excellent exchangeability for parts and components
7) Saves electricity
Control method:
Pendent line with press button or remote control or cabin or both
Crane girder:
The crane girder is of welded girder construction. This result in lower dead weight with a high degree of vertical and horizontal rigidity and small wheel loads being transmitted to the crane runway!
Bridge Crane system consists of three major components.
The Bridge Crane, which traverses across the runway
The hoist & trolley, which traverses across the bridge and lifts up and down
The runway, which is tied to the building structure.
Top Running vs. Under Running
Capacity - Although under running can be up to 25 ton capacity, the practical limit is more like 15 tons and the economic sweet spot is 1 to 7.5 ton range.
Support Structure - Under running can be suspended directly from the overhead steel (for lighter cranes). Top running cranes will require a bracket off the building support steel (up to 10 tons capacity) or independent columns for heavier capacities.
The top running configuration is best used in cases where the end user has issues with headroom. The most space efficient configuration is the double girder, top running crane system. When headroom is not an issue a top or under running configuration can be used with either the double or single girder bridge crane.
