Product Overview
Used lifting equipment refers to various types of heavy-duty hoisting machinery specialized for engineering and industrial applications, including overhead cranes, gantry cranes, traveling cranes, and vacuum lifters. All equipment is originally used on construction sites, in factories, and at ports, having undergone professional disassembly and inspection, fault repair, complete maintenance, component replacement, and comprehensive refurbishment. After restoration, the equipment meets all safety standards and can reliably perform vertical lifting, horizontal transportation, and precise positioning tasks. As special-purpose machinery, this series of used lifting equipment complies with operating regulations and delivers stable performance, widely applied in construction, municipal infrastructure, port logistics, mining and energy, steel structure installation, factory equipment relocation, and other scenarios. It also supports customized ancillary services, making it a core preferred choice for global engineering firms, rental companies, and manufacturers seeking cost-effective lifting solutions.
Technical Principles
Used lifting equipment relies on the coordinated operation of mature mechanical, hydraulic, and electrical control systems, adapting to various heavy-lifting conditions. Its core operating principles are standardized and regulated, ensuring strong safety and stability:
1. Power Transmission System: The equipment uses electric motors, diesel engines, or hydraulic power units as its primary power source, transmitting power through gearboxes and brakes to winches and hydraulic cylinders, driving wire ropes and chains to lift, lower, and adjust loads. Power output is smooth, and transmission efficiency is high.
2. Multi-Dimensional Operating Mechanisms: Equipped with four core systems—winch mechanism, luffing mechanism, slewing mechanism, and traveling mechanism—the slewing bearing paired with a hydraulic motor enables 360° omnidirectional operations without blind spots. Tire, track, and rail-based traveling systems accommodate diverse site mobility and fixed-point work requirements.
3. Intelligent Safety Protection System: The entire machine comes standard with torque limiters, height limiters, weight sensors, emergency braking systems, and other safety devices. Relying on hydraulic transmission and electronic overload protection technologies, it effectively mitigates risks such as overloading, tipping, and impact during operations, ensuring safe and stable lifting throughout the process.
Core Performance and Operational Standards
All refurbished used lifting equipment strictly adheres to special equipment operating standards, with core performance parameters fully compliant:
1. Broad Load Specifications: Rated lifting capacities span the full range from 0.5t to 500t, with lifting heights reaching tens of meters, meeting the needs of light-, medium-, and heavy-duty lifting tasks.
2. Excellent Power Performance: Motor and engine output power can be restored to 85%–95% of their original rated values, while key operating parameters such as slewing speed, luffing time, and traveling speed fully align with original design standards.
3. Stable Hydraulic System: Hydraulic system pressure remains constant, flow is uniform, with no leaks, jams, or pressure drops. Start-up and shut-down are smooth, ensuring precise and controllable lifting operations.
4. Safe and Reliable Structure: Core structural components like booms, frames, and outriggers show no cracks or permanent deformation, with overall structural strength meeting standards and load-bearing capacity remaining stable.
5. Compliance with Safety Inspections: Safety protection devices are complete and effective. Following load tests, brake tests, static stiffness tests, and other professional inspections, the equipment passes construction site safety checks and special equipment compliance reviews. Its operational efficiency and durability approach that of new machines, supporting long-term continuous use.
