Components

Beams are made of well-chosen steel plate, and processed by shot-blasting technology, thus the intensity and toughness are reliable. On the main girders laid the rails for cross travel. The trolley adopts an electric Hoist fixed on the trolley frame as the lifting mechanism. CD model electric hoist with single speed and MD model electric hoist with double speeds are in choice according to your demand. Electric parts adopt international brand Siemens and Schneider.

Three control methods are for choice, including pendent line with press button, Remote control and cabin control.

1. The Motor adopted is top in China and features large overload capacity and high machinery intensity with low noise. With the protection level of IP44 or IP54, and insulation class of B or E, , the LH Overhead crane is able to meet the demand of general usage. 2. The electric parts adopt international brand Siemens, Schneider, or Chinese top brand Chint to ensure the accurate and safe operation. 3. Wheels, gears, and couplings are processed by medium-frequency quenching technology, abd have a great improvement in intensity, rigidity and tenacity. 4.Painting: a Primer and finishing paint   b Average thickness: about 120 microns   c Color: according to your request

Control Methods                                                                                      

Ground handle, wireless remote control or cab/operational room.

Advantages                                                                               

1. Low height, narrow width, light weight and compact structure.  The whole set can pass through the tunnel; what's more,

it can feed girder and erect girder in tunnel.
 2. The weight of the maximal part is no more than 6.6t and the length is no more than 10m which can meet the vehicle transportation rules.
 3. To meet the requirement of the limit of present railway, it can work under the condition of multiple tracks. The symmetrical design of main girder,

and to reserve the hole of bolts to erect girder bidirectional and shift span for erecting.
 4. Auxiliary trolley and upside-down charging gantry are added, and it has quite complete function which can lay track. It can erect the girder

of highway after modification.
 5. It can move a long distance on the Rail with self- power.
 6. Compact structure, easy to install and maintain for users. It only needs to disassemble partially when transfer site by train,

the upside-down charging gantry can fold and pack by itself without a hoisting machine.

Working Class Working Title Description

A4 Moderate Service This service covers cranes which may be used in machine shops or paper mill
Machine rooms, etc., where service requirements are moderate.  In this type of 
service the crane will handle loads 80% of the lift at rated capacity.
A5 Heavy Service This service covers cranes which may be used in heavy machine shops, foundries,
fabricating plants, steel warehouses, container yards, lumber mills, etc., and 
standard duty bucket and Magnet operations where heavy duty production is required.  In this type of service,

loads approaching 85% of the lifts at rated capacity.

A6 Severe Service This type of service requires a crane capable of handling loads approaching a rated
Capacity throughout its life.  Applications may include magnet, bucket, magnet/bucket
combinations for scrap yards, cement mills, lumber mills, fertilizer plants, container
handling, etc., with 20 or more lifts per hour at or near the rated capacity.
A7 Continuous Severe ServiceThis type of service requires a crane capable of handling loads approaching rated 
capacity continuously under severe service conditions throughout its life.  
Applications may include custom designed speciality cranes essential to performing
the critical work tasks affecting the total production facility.  These cranes must 
provide the highest reliability with special attention to ease maintenance features.
