5ton 10ton 15Ton 20ton LDA Single Girder electric hoist overhead Crane China Bridge
Product Description
1. Introduction
The LD type single girder 10t overhead crane is the most popular
crane for all type of workshops. It can be characterized by
advanced metal structure and higher steel strength, used together
with CD1 or MD1 electric hoist as a complete set.
These cranes are more efficient and require less
maintenance.working class A3-A5, working temperature is between
-25C to 40C.
This crane model recommended by the WTO and match China standard
JB/T1306-94.
LD crane has two operational methods- pendant or cabin (open or
closed type).

1. Main beam- The main traveling structure of the crane which spans the width
of the bay and travels in a direction parallel to the runway. The
bridge consists of two end trucks and one or two bridge girders
depending on the equipment type. The bridge also supports the
trolley and hoisting mechanism for up and down lifting of load.
2. End trucks- Located on either side of the bridge, the end trucks house the
wheels on which the entire crane travels. It is an assembly
consisting of structural members, wheels, bearings, axles, etc.,
which supports the bridge girder(s) or the trolley cross member(s).
3. Bridge Girder(s)- The principal horizontal beam of the crane bridge which supports
the trolley and is supported by the end trucks.
4. Runway - The rails, beams, brackets and framework on which the crane
operates.
5. Runway Rail- The rail supported by the runway beams on which the crane
travels.
6. Hoist- The hoist mechanism is a unit consisting of a motor drive,
coupling, brakes, gearing, drum, ropes, and load block designed to
raise, hold and lower the maximum rated load. Hoist mechanism is
mounted to the trolley.
7. Trolley -The unit carrying the hoisting mechanism which travels on the
bridge rails in a direction at right angles to the crane runway.
Trolley frame is the basic structure of the trolley on which are
mounted the hoisting and traversing mechanisms.
8. Bumper (Buffer)- An energy absorbing device for reducing impact when a moving
crane or trolley reaches the end of its permitted travel, or when
two moving cranes or trolleys come into contact. This device may be
attached to the bridge, trolley or runway stop.
