SLA Spreader Linear Actuator

SLA Linear Actuators: The Comprehensive Solution for Port Applications

Perfect Solution for Crane Operations in Ports

The SLA - Spreader Linear Actuator from Pfaff-silberblau is specially designed for use in port cranes and container handling systems. With its high load capacity, precise positioning, and robust construction, it contributes significantly to the efficiency and safety of port logistics.

Precision and Control: Our Pfaff lifting gears offer extremely precise load control, which is essential for the safe and efficient movement and positioning of containers.

Maintainability: Mechanical lifting gears do not require hydraulic fluids or compressed air systems, simplifying maintenance and minimizing the risk of leaks. This results in greater reliability and lower operating costs. SLA linear actuators also benefit from low maintenance because they have fewer moving parts and do not use hydraulic fluids.

Energy Efficiency: Pfaff lifting gears and SLA linear actuators are characterized by high energy efficiency because they do not require a continuous power supply. This reduces operating costs and contributes to more sustainable resource use.

Environmental friendliness: Without hydraulic fluids, there is no risk of environmental pollution from leaks. This makes our screw jacks and linear actuators an environmentally friendly solution for port applications.

Corrosion resistance: In coastal ports where the air is salty and humid, our Pfaff screw jacks with C5 paint, special spindle protection, and rust-proof components offer excellent corrosion protection.

Temperature resistance: Our screw jacks are equipped with heating and temperature monitoring to withstand extreme temperature differences. This prevents lubricants from becoming too viscous in cold conditions and enables early detection and correction of potential problems, increasing operational reliability and reducing unplanned downtime.

High reliability and customized design: SLA linear actuators offer an electromechanical solution with high reliability and can be customized to the specific requirements of your application. This ensures optimal performance and efficiency, regardless of the unique challenges of your environment.
