Rail Transfer Cart, TrT, TWEKO

The TWEKO TrT series rail transfer cart is a specialised industrial transporter designed to move large workpieces along a rail track between process zones in a paint shop. With a load capacity of up to 20,000 kg, the TrT mechanises the transfer of heavy products between preparation, painting and drying areas.

A key feature of the TrT is its integrated hydraulic lifting system and dedicated workpiece securing devices. The system therefore provides both transportation and positioning, improving access to different surfaces during painting and other process operations.

Applications

• Transfer of large workpieces between process areas
• Paint shops
• Spray and paint booths
• Surface-preparation stations
• Drying areas
• Installation and servicing operations involving heavy workpieces
• Production lines incorporating several consecutive process zones

Rail Travel

The TrT travels along a fixed rail track installed through the paint-shop area. The rail system provides a defined travel path and allows a large workpiece to be transferred between process positions without repeated crane handling.

• Travel speed: 3 m/min
• Maximum travel: up to 14,400 mm
• Guided movement along a fixed rail path
• Electrical travel control

Load Capacity

• Maximum load capacity: 20,000 kg
• Suitable for heavy and oversized industrial workpieces
• Designed to transfer workpieces between consecutive process zones

Integrated Hydraulic Lift

An integrated hydraulic lifting mechanism allows the position of the workpiece relative to the cart platform to be changed, providing improved access to its surfaces.

The lifting system is adapted for paint-shop applications. Together with dedicated securing devices, it holds the workpiece in the required position during process operations.

• Hydraulic workpiece lifting
• Mechanised positioning
• Dedicated load-securing elements
• Improved access to lower and side surfaces

Drive System

Cart movement is provided by a geared drive system. The pneumatic section of the equipment requires compressed air at a working pressure of 7 bar. Travel is electrically controlled.

• Geared drive transmission
• Pneumatic system pressure: 7 bar
• Smooth rail movement
• Electrical control

Construction

The TrT is a low-profile industrial platform running on steel rail wheels. Its structure is designed for high loads and integrates both the hydraulic lifting mechanism and dedicated workpiece securing equipment.

• Industrial load-bearing frame
• Steel rail wheels
• Integrated hydraulic lifting system
• Geared drive mechanism
• Workpiece securing system
• Electrical control system

Key Parameters

• Load capacity: up to 20,000 kg
• Travel speed: 3 m/min
• Maximum travel: 14,400 mm
• Pneumatic system operating pressure: 7 bar
• Wheel diameter: 270 mm
• Overall dimensions: 9200 × 2400 × 350 mm
• Cart weight: 3200 kg

Configuration for Paint-Shop Applications

The TrT is designed for operation in industrial painting environments. Depending on the technical specification, the equipment can be configured with consideration for enhanced spark-prevention and operation in potentially explosive atmospheres.

The exact configuration of drives, electrical components and control systems is determined according to operating conditions and project requirements.

Main Benefits

• Up to 20 t load capacity: transport of heavy and oversized workpieces
• Integrated lift: workpiece height can be adjusted without separate lifting equipment
• Guided rail path: controlled movement between working zones
• 3 m/min travel speed: stable process transfer along the production line
• Workpiece securing: dedicated fixtures provide stable load positioning
• Improved surface access: lifting mechanism facilitates work on lower and side areas
• Optimised material flow: one transporter can move a workpiece through several consecutive process stages

Custom Configuration

The TrT rail cart can be adapted to a specific production process. Platform dimensions, travel distance, lifting-system configuration and workpiece fixtures can be customised according to the customer’s technical requirements.

The TWEKO TrT rail transfer cart combines transportation and positioning of heavy workpieces in a single system. Its load capacity of up to 20,000 kg, rail travel of up to 14.4 m and integrated hydraulic lifting system make it a practical solution for mechanising material handling in paint shops and other industrial production areas.
