Details

The company has high precision CNC lathe, CNC machining center, grinder, milling machine, lathe and other various types of large-scale processing equipment, 60T tensile testing machine, magnetic powder flaw detector, ultrasonic flaw detector, hardness tester and other testing equipment. The company has more than 30 employees, of whom more than 30% employees with college degree or above, 45% employees are senior technical personnel. The staff has high comprehensive quality and strong technical force. Under the technical guidance and training of senior engineers with many years of experience in manufacturing port machinery fittings, a group of young technicians with excellent skills have been developed.
1) Customization: We have a strong R&D team,and we can develop and produce RAIL CLAMP according to the drawings or samples the customers offered.
2) Cost: We have one CNC machining factory.So we can offer the price and products directly.
3) Quality: We have our own testing lab and the most advanced and complete inspection equipment,which can ensure the quality of the RAIL CLAMP.
4) Advantage: Our engineer all come from ZPMC. So they are very familiar with the port cranes.
5) Capacity: We have a lot of processing equipment, we can meet the needs of different customers with different purchase quantity.
6) Service: We focus on developing high-quality RAIL CLAMP for top-end markets.Our main customers are all the world's leading crane factories and the world's leading ports;
For any new RAIL CLAMP of the customers,we will communicate with customers professionally,listen to the views of customers and give useful suggestions for developing the RAIL CLAMP.

RAIL CLAMPS

 

1.0 Rail Clamp Models CXHV-LE/RP Models

rail-clamp-3rail-clamp-11

LE = Internal Hydraulic Power Unit

RP = Remote Hydraulic Power Unit

TS = Toggle style (clamping principle)

LH = Wedge style (clamping principle)

 

2.0 Principles of Operation

2.1 Toggle Style (TS)

rail-clamp-4

FS = SPRING FORCE

FC = CLAMPING FORCE

FA = APPLIED FORCE

FA = 2 x FC

FH = HOLDING FORCE

FH = FA x µ

 

2.2 Wedge Style (LH)

rail-clamp-5

International patents apply

Wedge is designed and profile machined to (spring compensated wedge) provide constant clamping force Fc.

FS = SPRING FORCE This would apply force to the wedge.

FW = WEDGE FORCE

FC = CLAMPING FORCE

FA = APPLIED FORCE

FA = 2 x FC

FH = HOLDING FORCE

FH = FA x µ

 

3.0 Design Highlights

rail-clamp-6

International Patents Apply

Spring compensated wedge

Wedge is designed to compensate spring as the spring force decreases. Thus Fc clamping force is constant. Refer to diagram below.

Compact, light weight & low height designed to fit into restricted space.
Easy to service

All coil springs designed for maximum life. fully protected with rust inhibiting grease & spring chamber protection cover.

All covers and rail clamp enclosure 304 SS.

 

3.1 Spring Force test

rail-clamp-7

To verify spring force by measuring the back pressure of the cylinder

Fully certified load tests on all models

 

3.2 Clamping Force test

rail-clamp-8

To verify clamping force by measuring with load cell between levers.

Fully certified clamping force tests on all models.
Clamping force Fc must be verified to confirm coefficient of friction product specification meet µ = 0.50 or µ = 0.25

 

3.3 Holding Force test

rail-clamp-9

Holding force is verified by pushing the test rail with hydraulic cylinder.
Test certificate available for: Water, Oil, Coal, Other Potash, Sulphur.
Tests may be done at customer request.
