Overview
Heavy lifting is a complete-system problem involving the load, center of gravity, lifting points, sling arrangement, angles, connections, equipment, environment, and governing lift plan. A product capacity label alone is not enough to define a suitable solution.
Nantong Qisheng can review source-backed wire rope, sling, assembly, and hardware families against the customer's approved lift information. Final lifting engineering and authorization must remain with competent responsible parties.
Frequently Asked Questions
What is required before a heavy lifting quotation?
Provide the approved load data, center of gravity, lifting points, equipment, sling arrangement, angles, connections, environment, quantity, standard, and documentation scope.
Can nominal sling capacity be used without reviewing the arrangement?
No. Sling angle, hitch, load distribution, end fittings, hardware, condition of use, and governing requirements affect the complete arrangement.
Can a custom multi-leg configuration be reviewed?
Yes. Provide a drawing or complete dimensional and load information, including lifting points and connection details.
Who approves the final lifting solution?
Final selection, lift planning, risk assessment, and authorization must be completed by competent responsible parties under the applicable requirements.
Customer Challenges
High-load requirements and non-routine load geometry
Multiple lifting points, sling angles, and connection compatibility
Custom effective lengths, leg arrangements, and terminal requirements
Abrasion, bending, corrosion, and site operating conditions
Project inspection, identification, documentation, packaging, and delivery controls
Engineering Considerations
Approved lift plan, load data, center of gravity, lifting points, and equipment
Sling arrangement, hitch, angles, load distribution, and connection geometry
Rope construction, diameter, effective length, end fittings, and hardware compatibility
Operating environment and inspection requirements
Applicable standards, competent-person approval, testing, and documentation scope
Recommended Solution
Start from an approved load and lifting arrangement rather than selecting from a nominal product range.
Review endless, ferrule-pressed, or socketed sling families and compatible rope, assemblies, and hardware as applicable.
Confirm every component, connection, angle, dimension, and required document for the complete arrangement.
Use drawing-based review for non-standard geometry, lengths, terminals, or project documentation.
Application Scenarios
Project and structural lifting
Review custom sling and connection requirements around an approved lifting plan and project specification.
Port and steel-plant handling
The source identifies endless slings for heavy lifting, port, and steel-plant applications.
Bridge and engineering work
The source identifies socketed sling applications in bridge and port engineering, subject to project-specific review.
Advantages
Factory Direct Supply
Coordinate multi-product procurement and production inputs through one manufacturing-focused supplier.
Custom Manufacturing
Review leg arrangements, effective lengths, end fittings, sockets, and drawing-based configurations.
Technical Support
Structure the product information needed to support the customer's lifting review.
Quality Control
Confirm required inspection, traceability, marking, testing, and documentation before production.
Application Result
The intended output is a documented supply configuration aligned with an approved lifting plan and defined component interfaces. This page does not replace lift engineering, risk assessment, inspection, or authorization by competent parties.
