33PC15/45rcs/55rcs/70rcs25 Hoisting and Trolley Mechanism for Tower Crane
PQC tower crane electrical control system is an economical electrical control solution based on the advanced foreign technologies.The system integrates slewing, luffing and hoisting mechanisms and power supply into a case.Compared with RCS,PQC electrical control system is more compact in structure and simper & more economical in circuit. This electronic control cabinet slewing mechanism adopts RCV speed regulation with features of stable operation and accurate positioning.Luffing mechanism adopts 2 control modes:3-gear self-coupling voltage reduction + eddy speed regulation or 2-gear pole-changing speed regulation. Hoisting mechanism adopts 3-speed motor pole -changing speed regulation. The traditional circuit is improved, overcoming problems of easy contactor damage and large impact on the mechanism during hoisting or speed reduction of motor. Temperature range:-20ºC-+40ºCHumidity:lower than 85%RH(no moisture condensation)
Altitude:the attitude of installation location shall not be higher than 1000m. Power grid quality:the voltage fluctuation range shall not exceed ±10% of the rated voltage. Power capacity shall be guaranteed fully.

Liquid or slurry like material is applied as a thin film to the surface of the heated drum, and raw material will be dried as the drum turns. The dried solids will then be scrapped off with a scrape.
Working Principle
Liquid or slurry like material is applied as a thin film to the surface of the
heated drum, and the material will be dried as the drum turns. The dried solids
will then be scrapped off with a scrape.
Features
1. Using steam or heat transfer oil results in large heating area, uniform
heating and high thermal efficiency.
2. The heat and mass transfer of wet material film in the same direction helps
achieve higher drying rate.
3. Yutong scraper drum drying machine is particularly suitable for drying thermosensitive materials.
