a. Gooseneck. The gooseneck connects the trailer to the prime mover. It contains the landing gear, the fifth wheel plate, and the operating wheel for the gooseneck winch. It also houses the air reservoirs, glad hands, and electrical cable receptacle for the trailer service brakes and lights. b. Low Bed Platform. The low bed platform is the main load-carrying part of the trailer. It has a width of 10 feet 6 inches and a length of 28 feet. It contains the ramps for loading and unloading equipment and the tie-down points for securing the load. c. Rear Wheel Assembly. The rear wheel assembly consists of two axles, each with eight wheels and tires. The axles are steerable to reduce tire wear and improve maneuverability. The suspension is a leaf spring type with hydraulic shock absorbers.

The LTB 72.5-170D1/B is a . Its primary value lies in its reliability and low maintenance requirements over a 30-year design life. It is an ideal choice for utilities looking for a proven, high-endurance breaker that can perform in both standard and extreme geographical environments.

The "B" in its designation stands for a (pole beam), which holds the three independent poles, creating a robust and compact unit suitable for both indoor and outdoor installations.

: Because the arc itself generates a large portion of the pressure required for its own extinction, the operating mechanism needs to supply less than 50% of the energy consumed by traditional puffer-type breakers.

Contains the motor, spring, tripping/closing coils, and terminal blocks. Density Monitor: Constantly monitors the SF6cap S cap F sub 6 It contains the landing gear, the fifth wheel

Provides a clear visual, mechanical indicator of whether the breaker is open or closed, as well as the spring state (charged/discharged).

According to the product manual, the breaker comprises three isolated poles mounted together on a shared pole beam supported by a sturdy two-column steel stand. Each independent pole assembly is broken down into three physical sections: Low Bed Platform

Detailed breakdown of the circuit breaker components, gas system, and density monitors.

Utilizes the Auto-Puffer™ principle, which uses the heat of the electric arc itself to compress SF6 gas. This reduces the energy required for operation by approximately 50% compared to standard puffer interrupters .

Never attempt to disassemble the main drive spring casing. Spring force exceeds 2,500 N. Refer repair to factory-trained personnel.
