Product Description

LD-Single Girder Overhead Crane
Under Running Crane (LD)
The LD type single girder 2t 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.

The LD type of under running overhead crane (also called bridge crane )is the most popular designing since the very beginning.  Our annual turnout is 20,000 units for the whole market. The main girder adopts 6mm and 8mm thickness steel plate. Chinese workshop has a 1700mm clearrance above the rail, which is excellenct for the maintenance of the crane.  In some Middle East countries, the clearance is  less than this, and please indicate this data when you placing the order.

Specifications
Steel Plate Cutting and Treatment
The board was cut by auto-cutting machine.

Main Beam
We reserve the concept of "safety factor", and remain the traditional main beam fabrication methord. Each of the beam is made by 6mm thickness of side board, and 8mm top and bellow board. 

Bearing System 
The  reducer is hardtooth designing. Bearing is HA/WA/LUO 3 brands. Casting box type. The gear box is made by our factory in order to give a reliable quality. The market has many suppliers, and some of them can get 50% price than ours.  However, we do not reduce the quality in order to reduce the cost.

Safety Device
 Long travel limit switch
 Cross travel limit switch
 Counter-weight and pedal limit switch for hoisting
 Pedal limit switch for lowing
 Overload limit switch

End Trucks (Carriage)
Soft start driving system(380v only) makes the long travel smoothly, reduces noise.  Modular system designing gives the crane more free working space. Unique conbinations with steel profiles sections for maximum distance between suspensions.  

Double C-track Festoon System

 4mm thickness national standard trackpull  and push wheel with sealed bearing
 Flat cable for strong life.
 Electrical box has indication of working.
 This double C-track festoon system makes the driver can be seperate from the hoist , so that give a maximum safety protection. 

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.
