The Difference Between Self-propelled Modular Transporter and Modular Trailer

1. Self-propelled modular transporters and modular trailers

A self-propelled modular transporter is a platform vehicle consisting of a large number of wheels. It is also known as self-propelled modular trailer. These types of vehicles are basically used to transport heavy and bulky objects such as industrial equipment and project components that cannot be safely handled using conventional trucks, such as huge bridge sections. However, these trucks can be used to provide braking and traction to self-propelled modular transporters when descending and tilting. These types of vehicles are commonly found in industries such as the oil and construction industries. They are also suitable for shipyards and offshore industry, factory construction sites, road transport and transport on oil platforms.

2. What is the difference between a self-propelled modular transporter and a modular trailer?

Traditionally, the main difference between a self-propelled modular trailer and a modular trailer is the power pack unit (PPU) of the self-propelled modular transporter. While this is the primary steering system for self-propelled modular carriers, modular trailers have a different mechanical steering system. The mechanical steering system in a modular trailer is contained in the towing vehicle that tows the trailer during transport. For modular trailers, the trailer can use a combination of gooseneck detach and drawbar.

Different drive modes: The self-propelled modular transporter is driven by a component called PPU. The steering control system includes multiple components, including a steering hydraulic pump, an angle sensor, a proportional sandwich valve, and a swing cylinder. The drive mode for a modular trailer is the setting in which the trailer is towed by a heavy-duty tractor. The modular trailer has a steering system with hydraulic planar linkage drive. In this way, by adjusting the hydraulic steering system and using various reasonable linkage layouts, the vehicle can achieve the minimum turning diameter while driving normally. The supporting members of the trailer components have a strong solid box beam frame.

Power pack unit and power pack: Self-propelled modular transporter power pack unit (PPU), the power unit is the unit that provides power to drive the self-propelled modular transporter and helps steer the axles. This is the most important characteristic of a self-propelled modular transporter, especially how it differs from a modular trailer. Specifically, the PPU is the main power source for the steering electrical system of the self-propelled modular transporter. Most notably, the PPU is responsible for powering the hydraulic systems used to control the axle height and braking system. The power pack (PP) unit of a modular trailer is only used to provide power to help steer the axle. PP is less powerful compared to PPU for self-propelled modular transporters. The modular trailer's hydraulic power unit and controls can be used to perform many functions including trimming, steering and maintaining the vehicle combination.
