Flat-top Tower Crane For High-rise Construction

Application Scenarios
The WA7015-10E flat-top tower crane features a maximum lifting capacity of 10 tons, a 70-meter jib, and a freestanding height of 61.5 meters. It is primarily designed for large-scale civil engineering projects, such as super-high-rise residential buildings, large public venues, and bridge construction.
Core Customer Pain Points
Overseas job sites often face five major challenges: traditional tower cranes involve numerous loose parts, requiring multiple skilled workers for over three days of continuous on-site assembly-driving up labor costs and delaying the start of operations; components vary in length, leading to inefficient container packing and wasted space, which increases the number of shipping containers and keeps logistics costs high; outdated electrical control systems cause jarring starts and stops, risking damage to loads like rebar and prefabricated wall panels, resulting in rework and schedule delays; procurement is often limited to the bare main unit, requiring fragmented sourcing of mast sections, wall ties, and operator cabs from multiple vendors, with repeated restocking incurring additional shipping fees; and long-term, high-intensity operations in the field make core components (bearings, motors, gears, etc.) prone to failure, where a lack of spare parts leads to prolonged downtime and work stoppages.
Product Solutions
This crane utilizes a standardized, modular pin-connection structure with uniform component dimensions. It is equipped with an intelligent PLC control system ensuring smooth, stable hoisting and slewing operations. With an overall working class of A4 and a slewing mechanism class of M5, it is well-suited for high-intensity, continuous construction. The complete set-including the main unit, mast sections, wall ties, and operator cab-is supplied as a comprehensive package and shipped in unified containers. The crane offers a rated load capacity of 10 tons and a wide operating range via its 70-meter jib. It ships with a mechanical test report and acceptance video, holds EU CE certification, and supports customization of the crane body color and nameplate logo.

Tangible Customer Benefits
Modular assembly requires only 3–4 workers and just two days to complete the installation of the entire unit, effectively halving labor hours and shortening the wait time before operations begin. Components are neatly packed for high container utilization, reducing the number of shipping containers required; shipping the complete equipment set in a single consignment eliminates the extra freight costs associated with piecemeal restocking. Smooth electrical control and precise hook positioning significantly reduce rework caused by damage to building materials and boost daily lifting efficiency. Core components-such as original-manufacturer motors, bearings, and gears-offer lower failure rates; combined with a one-year warranty and 24/7 online technical support, equipment issues are resolved quickly, ensuring project schedules remain on track. We do not compete on the price of the bare machine alone; instead, by providing a complete accessory package and long-term technical service, we minimize the comprehensive costs across the entire chain-including labor, logistics, construction, and O&M.
 

Company Profile
Tianjin Huizhi Import & Export Trade Co., Ltd. was established in 2025 and specializes in the export of heavy construction lifting machinery, such as tower cranes. Backed by a professional technical team, the company has established stable, long-term partnerships with over 20 general construction contractors both domestically and internationally.
Customer Procurement Pain Points
Overseas project procurement often involves three major challenges: purchasing only the main unit while lacking matching mast sections or wall ties, necessitating piecemeal sourcing and repeated shipments that incur high secondary freight costs; a lack of installation experience among overseas personnel, forcing the expensive hiring of foreign technicians; and slow spare parts delivery following core component failure, leading to forced work stoppages and project delays.
Our Core Advantages
One-Stop Complete Supply:Equipment configurations are tailored to site height, available space, and local grid voltage. The main unit and all matching components are shipped together in a single container, eliminating the need to source parts piecemeal from multiple suppliers.
Comprehensive Customs Clearance Qualifications: Each unit comes with actual factory footage, mechanical inspection reports, and EU CE certification, ensuring smooth customs clearance and avoiding fines caused by cargo delays at the port. Comprehensive Technical Support: Pre-sales support includes equipment livery and custom branding nameplates; in-sales service provides bilingual (Chinese/English) installation manuals and 24/7 remote online guidance, with the option to dispatch engineers overseas for on-site installation, commissioning, and operator training; post-sales support covers a 12-month warranty on core components-such as motors, bearings, and gears-and prioritizes logistics for urgent spare parts replacement.

One-stop procurement eliminates the communication costs associated with comparing multiple suppliers; remote technical guidance saves on expensive foreign technician service fees; consolidated shipping for complete equipment sets avoids additional freight costs for separate shipments; and robust warranty and spare parts support ensure project schedules remain on track. Compared to purchasing low-priced standalone units, a complete package of accessories and after-sales support helps customers save significantly on hidden costs.
