We have been designing, supplying and operating segmental lifter (also known as a launching gantry or launching grider) since 2006. Our 150 ton U Type LRT segment lifter equipment have been used to erect the decks of suspension bridges, cable stay bridges and land/sea viaducts in both steel and concrete.
We offer a complete design and supply service, with site supervision to assist and train our client's site team to assemble, commission, operate and maintain the gantries. We are also happy to pass the steel fabrication drawings to our clients so they may fabricate the steelwork themselves local to the project site to save costs.
Each of 150 ton U Type LRT segment lifter equipment is designed specifically to meet the loads and geometry of each project, and to arrive at the most cost effective overall solution when considering the cost of the gantry, the erection schedule, the labour required to operate, the erection loads on the permanent works and future re-use value.
Huada 150 ton U Type LRT segment lifter equipment are designed for safety. Winches are equipped with double breaking system. Upon request we provide Triple breaking system. Emergency stop button, Limit switch, sensor are located at designated location.
1. Have the function to monitor and record operation status of segmental lifter, the data could be recorded in local monitor and stored in the remote server to meet the demand on accidents analysis of segmental lifter;
2. Have the function to monitor wind velocity in the real time, which reminds driver to operate the segmental lifter safely.
3. Have the function of long distance monitoring on safety state of swgmental lifter at real time, which could meet the demand on remote management.
2. Our Advantage
With Huada 150 ton U Type LRT segment lifter equipment, the container terminal operator can reduce the number of container handling machine types and interfaces, since horizontal transport and stacking are done by one machine type.
1. Latest drive technologies, variable motor speeds and integrated power management reduce operating costs and increase eco-efficiency
2. Excellent handling, acceleration, speed
3. Innovative driver assistance features: safer operation, fatigue reduction
4. Reduced maintenance thanks to direct drive units, high-quality components
1. 14 months warranty when products leave the factory, or 12 months warranty after installation and commissioning in addition to the human damage factors.
2. 2 years spare-parts provided for better maintenance.
3. Professional technical staffs provide installation, commissioning and training services. The installation team can be sent to local site to install for customer.
4. Delivery with English user manual, parts manual, product certification and other relevant certificates.
5. Technical advisory for any time.
6.Test before shipment
1. Delivery time
Within 30 to 40 days after receiving the receipt of deposit.
Wood case for electric parts, accessories; large sections will be loaded onto bulk cargo ship after packing.
Generally 35 days to 50 days to destination port.
1. What's the information should I provide when inquiry about 150 ton U Type LRT segment lifter equipment?
a. we need the Bridge Drawing;
b. The Precast Segmental drawing.
2. What's the segmental erection method about the segmental lifter?
It is erection by Balanced cantilever method.
3.What are inspection standard for load test of segmental lifter?
a. Dynamic load test
1.1 times rated load, main girder does not down deflection, all mechanisms work well, performance parameters meet the design demand, all limit switches and safety protection interlock devices are reliable, all spare parts does not have cracking and flexible connection, all motors and contactors are not overheat.
b. Static load test
1.25times rated load, all mechanisms work well, the crane stops 20-30min as trial load is lifted 10cm high, then measure main girder down deflection(theodolite, ruler). Put down trial load to measure main girder upper camber, repeat 3 times, steel structure does not have permanent deformation.
4.what is the Launching Mechanism?
It is by hydraulic.
5.How about maintenance of segmental lifter?
a. Lubricating:Working performance and service life of all mechanisms of crane depend on lubricating to a big extent.
b. Steel wire rope:Fracture of wire has to be specially noticed. A new steel wire rope has to be changed immediately with the condition of broken wire, broken strands and wear loss to scrapping standard.
c. Spreader: The spreader has to be checked regularly.
d. Pulley block:Mainly check rope race wearing condition, check whether wheel flange is cracked and whether pulley could get stuck in the axle or not.
e. Brake: Check one time per shift; The brake should be in accurate movement, and pins do not allow to be stuck. Brake shoes shall fit brake wheels correctly; the brake shoes interval shall be equal to open them.
