2. Description of QTZ series tower Crane
1) the tower crane is one of the most popular type and hot-selling self-erecting tower crane, which is researched and designed by Institute of Building Mechanization of China Academy of Building Research. It absorbs many advanced technology both from China mainland and abroad.
2) We adopt to use Dual drawbars structure on lifting boom, which enables the lifting boom to be unfer no stress at lifting surface other than uniaxial stress, and moreover, it gets rid of the stress peak. It greatly improves the fatigue safety performance of lifting boom.
3) Adopts VVVF stepless speed variation device for lifting, radius changing and slewing mechanisms, to make sure it works steadily and effectively, it also lowers the maintenance cost.
4)We can offer crane standard sections such as the FO/23B standard sections for customers to choose from.
3. Service
1. ) Providing timely delivery, standby engineers are ready to solve any problems
2. ) Providing 12 (twelve only)months product warranty period, with ample spare parts
3. ) Providing work site installation guidance and training of operation and maintenances

Polymer Concrete Cells For ER/EW Processing Of Nonferrous
- Vinyl ester resin monolithic casting electrolytic cells
The Internal layer is a monolithic tank made with multiple layers of fiber-reinforced vinyl ester resin (FRP) complying with chemical barrier international norms that assure long-term impermeability and corrosion resistance.
The Intermediate layer is the structural core made with polymer Concrete, with a patented formulation to achieve a low coefficient of thermal expansion, providing long-term structural integrity with low thermally-induced stresses
The External layer is a standard seal layer of FRP that further protects the structural core from electrolyte splashes and spills. Optionally,this external seal may be specified with multi-layered oriented fiber reinforcements to guarantee trouble-free operation in unusually extreme operating environments.
Benefits of electrolytic cells
Long-term impermeability, free of corrosion, 20+ years warranty
Our monolithic internal tank manufactured with multiple layers of fiber-reinforced premium vinyl ester resin. It has continuous service without leakage, free of corrosion and structural flaws which operating under normal conditions as specified for each project.
Swift, accurate and less costly installation
Electrolytic cells include features that allow reduction of 25% or more in time needed for cell erection, alignment and leveling compared to time required with conventional polymer concrete cells. Dimension tolerances for electrolytic cells are consistently tight, simplifying installation in the most demanding applications,including plants with automated crane systems.
Minimum cleaning time and water consumption
The rounded internal shape,optional sloped cell floors,and smooth,flat finish of the internal tank,facilitate water sweeping and drainage of heavy sludge,with reduced water usage and accelerating return to service after each cleaning.
Minimum maintenance cost
The robust, virtually impervious internal tank that is chemically bound to the polymer concrete structural core during molding is tolerant to operating abuse its smooth,non-stick surfaces minimize adhesion of contaminants.
Maximum operational safety
The structural core of electrolytic cells is bolstered with sturdy external seismic reinforcement blocks confining its floor supports, and includes a robust, internal bidirectional, pultruded FRP bar mesh reinforcement which positively maintains integrity should the cell fail due to catastrophic events. Electrolytic cell installation protocols call for lateral wall collaboration between cells,thus reducing stress levels of cell around 40% under normal operating conditions.
