Precast Concrete Production

In the precast production and processing industry, cranes are crucial to achieving efficient and safe production. Covinicrane’s material handling solutions provide comprehensive crane systems tailored to meet the industry’s needs. Our solutions ensure safer and more efficient handling of heavy and large precast concrete components throughout the production, transportation, and installation phases. As a leading supplier of lifting equipment, COVINICRANE specializes in the design, manufacturing, sales, transportation, and installation of various cranes, including gantry cranes, rubber tyred gantry cranes, and overhead cranes. Our cranes, with lifting capacities ranging from 10 to 500 tons, are ideal for lifting precast concrete components, steel prefabricated components, wooden building components, composite material components, and other prefabricated elements. We assist you in selecting the appropriate crane based on your application and the materials you need to lift. Overhead cranes, gantry cranes, and rubber tyre gantry cranes are highly favored for lifting and transporting precast concrete components. They significantly enhance operational efficiency, reduce labor costs, and ensure safe handling of heavy loads, thereby minimizing the risk of accidents and safeguarding the safety of on-site workers.

Road & Bridge Construction

In modern road and bridge construction, efficiency, safety, and precision are critical. Heavy and oversized components such as pre-cast beams, bridge segments, and concrete girders must be transported and lifted accurately to ensure timely project completion. High-quality lifting solutions play a pivotal role in meeting these demands, providing reliable performance, and reducing construction risks.

Garbage Disposal Industry

The semi-automatic control grab crane for garbage handling is the core equipment of the garbage feeding system of the municipal solid waste incineration plant. It is located above the garbage storage pit and is mainly responsible for the feeding, handling, mixing, picking and weighing of garbage. Our team of experienced engineers has extensive knowledge in waste and biomass handling, enabling us to provide reliable and efficient lifting solutions for WtE facilities. We understand the unique challenges and requirements of this industry, and our expertise can help simplify complex decision-making processes.

Oil and Gas Industry

In the oil and gas industry, professional cranes and other lifting equipment play a crucial role in the transportation and packaging of raw materials, as well as the storage and distribution of finished products. Especially in environments that are flammable and explosive, appropriate lifting equipment can significantly reduce the risks associated with manual operations and ensure the smooth progress of the production process. Choosing lifting equipment specifically designed for the oil and gas industry has become a key factor that companies aiming to enhance production efficiency, ensure product quality, and maintain safety standards must consider.

China 3 Sets Double Girder Gantry Crane

Project: Double Girder Gantry Crane

Lifting capacity: 32t

Lifting height: 12meters

Span: 24meters

Control method: Remote control

case23

I. Project Background

Deyao Stone Raw Material Trading Center is a large stone industrial park integrating storage, transfer, loading & unloading of granite and marble blocks. Each raw stone block weighs heavily, requiring frequent lifting work including truck unloading, stacking, transfer and outbound loading every day. The old lifting equipment had insufficient load capacity and limited working span, causing severe swinging during heavy lifting, low operation efficiency and potential safety hazards, failing to support large-scale stone circulation of the park. After on-site inspection of our standardized production workshop and witnessing the full prefabrication process of double girder gantry cranes, the client customized heavy-duty double girder gantry cranes for all-weather heavy lifting work at No.2 open-air raw material yard.

II. Customized Equipment Solution

Targeted structural optimization is carried out based on special lifting conditions of stone blocks. All structural components are prefabricated, anti-corrosion painted and tested under no-load & full-load conditions in our workshop, then split into modular parts and delivered to site by flatbed trucks for assembly

1. Main Double Box Girders

Fabricated with thickened Q355B high-strength steel plate through integral welding, featuring excellent bending & torsion resistance to greatly reduce girder deformation under eccentric lifting. Full-length maintenance walkways with guardrails are equipped on both sides for convenient daily maintenance.

2. Rigid A-type Leg Frame

Integrated double A-type legs with widened load-bearing base and stable stay cables deliver high wind resistance, eliminating obvious swinging under strong wind for stable stone lifting.

3. Heavy-duty Trolley Lifting System

Stone-industry dedicated lifting trolley equipped with double brake winch system (service brake + safety brake for double protection) and variable frequency buffering speed regulation to achieve impact-free lifting & lowering. Matching stone lifting slings and steel wire ropes can be supplied as a full set.

4. Full Set of Outdoor Anti-corrosion Protection

The whole crane undergoes sand blasting rust removal plus 3 layers of industrial anti-corrosion orange paint. Fully sealed waterproof & dustproof electrical cabinets, rain covers for motors & reducers and dust housings for traveling mechanisms resist erosion from yard dust and rain to extend service life.

5. Modular Split Design

The crane is split into independent modules including main girders, A-legs, maintenance walkways, lifting trolley and electrical components. Prefabricated parts are transported separately and quickly assembled on site with truck cranes to greatly shorten construction period.

III. Project Implementation Process

1. On-site Survey & Solution Customization

Our professional engineers conduct precise on-site measurement of yard span, lifting height, rated load and daily operation frequency, then provide special drawings and load calculation reports to confirm customized solutions targeting stone lifting pain points.

2. Standardized Workshop Production

All components follow national crane standards in cutting, welding, non-destructive testing and anti-corrosion painting. Full crane tests under no-load, half-load and rated full-load are completed before delivery with full set of factory qualification certificates issued.

3. On-site Installation, Commissioning & Handover

Professional installation team completes girder connection, leg fixing, electrical wiring and overall commissioning on site. Simulated safety tests under no-load, half-load, full-load and overload conditions are carried out successively, and formal handover is done after all indicators meet standards.

IV. Project Summary

This project is a benchmark customized case of our factory targeting open-air heavy lifting scenarios for stone raw blocks. Relying on core advantages of double girder gantry cranes including high load capacity, wide span, stable operation and weather resistance, together with one-stop full-process service, we accurately solve core pain points of raw stone transfer in stone yards. Our factory customizes 5t–200t single/double girder gantry cranes and overhead cranes for industries including stone, steel, precast components, sand aggregate and port yards, providing exclusive integrated heavy-lifting solutions.
