# Technical Summary – Potain MDT 219 J10 Tower Crane

## General Description

The Potain MDT 219 J10 is a modern topless (flat-top) top-slewing tower crane manufactured by Potain (Manitowoc). It is designed for medium- to large-scale construction projects requiring high lifting capacities, long working radii, and efficient operation in multi-crane environments. The flat-top design simplifies assembly and minimizes interference between adjacent cranes, making it particularly suitable for congested construction sites.

## Main Technical Specifications

| Parameter | Specification |
| --------------------------------- | ------------------------------------------ |
| Crane Type | Top-slewing topless (flat-top) tower crane |
| Maximum Lifting Capacity | 10 t |
| Maximum Jib Length | 65 m |
| Tip Load at Maximum Radius | 1.9 t |
| Maximum Freestanding Hook Height* | Approximately 70.4 m |
| Rated Load Moment | Approximately 2,000 kNm |

*Depending on tower configuration and local regulations.

## Structural Design

The MDT 219 J10 features a modular lattice tower structure allowing various tower heights and foundation configurations. Its topless design eliminates the traditional tower head and pendant bars, providing several operational advantages:

* Simplified crane erection and dismantling
* Reduced assembly time
* Improved efficiency in multi-crane installations
* Lower risk of jib interference
* Easier replacement of jib sections during assembly

## Hoisting System

The crane is typically equipped with the Potain 50 LVF Optima variable-frequency hoisting winch.

Main characteristics include:

* Variable-speed operation
* Smooth acceleration and deceleration
* Precise load positioning
* Reduced mechanical wear
* High lifting speeds for lighter loads
* Improved energy efficiency

Frequency-controlled drives minimize load oscillation and enhance operator control throughout lifting operations.

## Slewing System

The slewing mechanism is electronically controlled using variable-frequency technology, providing:

* Smooth and continuous slewing
* Accurate positioning
* Reduced dynamic loading
* Improved operational safety, particularly under windy conditions

## Trolley Travel System

The trolley mechanism is frequency-controlled to ensure:

* Precise load positioning
* Smooth acceleration and braking
* Reduced structural stress
* High operating efficiency

## Control System

The MDT 219 J10 is equipped with Potain's Crane Control System (CCS), an advanced digital crane management platform.

Key features include:

* Full-color graphical display
* Integrated diagnostics
* Operating and maintenance information
* Load moment monitoring
* Operating data recording
* User-friendly rotary control interface
* Standardized control philosophy across Potain crane models

Optional equipment may include:

* Potain Plus enhanced load charts
* Top Tracing 3 anti-collision system
* Power Control for reduced electrical demand
* CraneSTAR remote monitoring system

## Lifting Performance

Typical lifting capacities are:

| Working Radius | Capacity |
| -------------- | ------------------- |
| Near the tower | Up to 10 t |
| At 65 m radius | Approximately 1.9 t |

Actual lifting capacities depend on:

* Jib length
* Tower height
* Ballast configuration
* Wind conditions
* Crane configuration
* Applicable operating mode

## Electrical System

Depending on the selected configuration, the crane typically requires:

* Electrical supply: approximately 38–58 kVA
* Variable-frequency drives for all major motions
* Optional Power Control system to reduce peak power demand

## Safety Features

Standard safety equipment includes:

* Rated load moment limiter
* Overload protection
* Hoisting, trolley travel, and slewing limit switches
* Wind-related operating protection
* Electronic operational monitoring
* Emergency stop system
* Integrated fault diagnostics through the CCS platform

## Typical Applications

The Potain MDT 219 J10 is suitable for:

* Residential construction
* Commercial buildings
* Industrial facilities
* High-rise construction
* Bridge construction
* Infrastructure projects
* Multi-crane construction sites

## Key Advantages

* Maximum lifting capacity of 10 tonnes
* Maximum jib length of 65 m
* High tip load capacity of 1.9 t
* Modern CCS digital control system
* Variable-frequency drive technology for all principal motions
* Fast erection due to topless design
* Excellent suitability for congested job sites
* Energy-efficient operation
* High positioning accuracy and smooth load handling

## Conclusion

The Potain MDT 219 J10 is a high-performance topless tower crane positioned in the medium-to-heavy lifting class. With a rated load moment of approximately 2,000 kNm, a maximum lifting capacity of 10 tonnes, and a maximum working radius of 65 metres, it is well suited for demanding commercial, industrial, and infrastructure construction projects. Its modular design, advanced Crane Control System (CCS), and variable-frequency drive technology provide high productivity, excellent operational precision, and efficient long-term performance on modern construction sites.
