RCS Series Hoisting Mechanism for Tower Cranes
The RCS series tower crane hoisting mechanism is a compact lifting winch system used for tower crane lifting, replacement, repair and spare parts supply. It adopts a straight-line structural layout, planetary gear reducer and motorized speed regulation system to provide stable lifting performance for construction sites.
This series includes 70RCS25, 70RCS30, 70RCS40 and 70RCS50, suitable for tower crane models from QTZ125 to QTZ7050. It is suitable for tower crane maintenance companies, crane rental fleets, used tower crane refurbishing suppliers and overseas spare parts buyers.
RCS Hoisting Mechanism Model Selection Guide
The RCS series should be selected according to single rope pull, motorized trolley speed range, rope capacity and applicable tower crane model. The table below helps buyers quickly match the correct model.
| Model | Single Rope Pull | Double-Speed Trolley Speed | Motor Power | Rope Capacity | Applicable Tower Crane Model | Recommended Application |
|---|---|---|---|---|---|---|
| 70RCS25 | 2.5 t | 0–100 m/min | 51.5 × 2 kW | 550 m | QTZ125–200 / FO/23B | 8T–10T class tower crane replacement |
| 70RCS30 | 3 t | 0–80 m/min | 51.5 × 2 kW | 550 m | QTZ125–200 / FO/23B | Medium tower crane hoisting system |
| 70RCS40 | 4 t | 0–64 m/min | 51.5 × 2 kW | 550 m | QTZ722–7030 / H3/36B | 16T class tower crane / H3/36B replacement |
| 70RCS50 | 5 t | 0–46 m/min | 51.5 × 2 kW | 550 m | QTZ7050 | Heavy-duty tower crane hoisting mechanism |
70RCS40 Hoisting Mechanism for Tower Crane
70RCS40 is one of the key models in the RCS series. It is commonly used for tower crane models such as QTZ722–7030 / H3/36B. According to the available product information, 70RCS40 has 40kN single rope rated tension, 51.5kW motor power, 16/8T hoisting capacity, 550m rope capacity and φ20 wire rope diameter.
Main Structure and Working Principle
The RCS hoisting mechanism adopts a straight-line structural layout. The reducer uses a planetary gear reduction system. The motor can use a multi-speed electromagnetic brake three-phase asynchronous motor, conical rotor motor or torque motor according to configuration requirements.
- Compact layout: suitable for tower crane platform installation and replacement.
- Planetary reducer: provides strong torque transmission and reliable lifting performance.
- Motorized speed regulation: supports smooth lifting and better control during construction.
- 550m rope capacity: suitable for medium and high-rise construction applications.
- Multiple model options: 70RCS25, 70RCS30, 70RCS40 and 70RCS50 for different tower crane capacities.
How to Choose the Correct RCS Hoisting Mechanism?
Buyers should not choose the RCS hoisting mechanism only by appearance. The correct model should be confirmed according to:
- Existing tower crane model, such as FO/23B, H3/36B or QTZ7050
- Single rope pull requirement: 2.5t, 3t, 4t or 5t
- Required trolley / hoisting speed range
- Rope capacity and working height
- Motor power and reducer configuration
- Installation position and base frame dimensions
Application Markets
RCS tower crane hoisting mechanisms and spare parts are suitable for replacement projects in UAE, Saudi Arabia, Qatar, Kuwait, Kazakhstan, Uzbekistan, Indonesia, Vietnam, Philippines and African construction markets. They are especially useful for tower crane repair companies, rental fleets and used tower crane refurbishment suppliers.
