Construction sites rely on portable generators to power equipment and tools, as access to power is very limited or inaccessible. Bobby Ranker, product specialist at Bobcat, highlights the design and features of portable generators, considerations when sizing the units for projects and best practices during operation in this Q&A.
IRONPROS: What is the primary role of a portable diesel generator on remote construction sites with limited access to power?
Ranker: On remote construction sites with limited access to power, a portable diesel generator's primary role is providing a reliable and independent source of electricity. These generators are essential for powering a variety of construction equipment, tools and lighting necessary for the successful completion of projects in areas where the electrical grid is inaccessible or non-existent. Diesel generators are favored for their durability, extended runtime and ability to deliver high power output, making them well-suited to the demanding conditions of construction sites. Their portability ensures that they can be easily relocated as work progresses, while their robust performance under harsh environmental conditions supports uninterrupted operations and enhances overall productivity.
IRONPROS: What should individuals consider when sizing a generator for their project or operations?
Ranker: When sizing a generator for a project or operation, individuals should carefully consider several key factors to ensure they select the right unit for their needs. First, it's crucial to determine the total power requirements by adding up the wattage of all equipment and tools that will be used simultaneously, including any potential startup surges. A right-sized Bobcat generator will help minimize wet stacking. Wet stacking occurs when diesel engines run under-loaded or at low temperatures, leading to incomplete combustion and the buildup of unburned fuel and carbon deposits in the exhaust system. This can negatively affect engine performance and increase maintenance needs.
Next, evaluate the type of load—whether it's purely resistive, inductive or a combination—as this affects the generator's performance and efficiency. Additionally, consider the fuel source and runtime to ensure the generator can operate for the necessary duration without frequent refueling. All Bobcat generators have onboard fuel & DEF tanks with runtimes of at least 24 hours at 75% load, optional remote fuel and DEF connections allow for connecting external fuel and DEF tanks to further extend runtimes as needed. It's also important to account for the operating environment, as factors like temperature, altitude and weather conditions can impact the generator's performance. Finally, factor in the generator’s portability and ease of setup if the project involves frequent relocation or setup changes. By carefully evaluating these aspects, individuals can choose a generator that provides reliable power, minimizes downtime and meets the specific demands of their operation.

IRONPROS: Equipment on construction sites have a wide range of power requirements. What features should individuals look for to ensure power compatibility and help with power management?
Ranker: On construction sites, where equipment varies widely in power requirements, individuals should look for several key features in a portable generator to ensure power compatibility and effective power management. First, choose a generator with a flexible power output range and multiple outlets to accommodate different types of equipment, including those with varying voltage and current needs.
Additionally, Bobcat generators with paralleling load management systems can help balance power distribution and prevent overload by only running the required number of generators to handle the connected load in a multi-generator configuration. Features like digital displays for real-time monitoring of power usage and remaining runtime can also aid in efficient power management. Ensuring the generator has sufficient capacity to handle both continuous and surge loads will further ensure reliable performance and prevent potential disruptions on the job site.
IRONPROS: Let's go into the design of portable generators. What are the benefits of an enclosed portable generator over an open cage design?
Ranker: When considering the design of portable generators, an enclosed unit offers several notable benefits over an open cage design. Enclosed generators are typically housed in a robust, weather-resistant enclosure that provides superior protection against environmental elements such as rain, dust and extreme temperatures—enhancing durability and extending the lifespan of the generator.
This enclosure also significantly reduces noise levels, making enclosed generators a quieter option, which is especially advantageous in noise-sensitive areas or residential settings. Additionally, the enclosed design often includes better security features, safeguarding the generator from theft and vandalism. The enclosure also aids in efficient sound attenuation and can contribute to better fuel efficiency by maintaining optimal operating temperatures. Overall, while open cage designs might be more accessible and cost-effective, enclosed Bobcat portable generators offer enhanced protection, quieter operation and improved security, making them a preferred choice for many users.

Ranker: In remote job sites, where portability is crucial, opting for a towable generator offers several distinct advantages over a skid mount system. Towable generators come with a built-in hitch and sturdy wheels, making them easy to transport across rough or uneven terrain and between different locations on the job site. This mobility facilitates quicker setup and relocation, which is vital for dynamic construction environments where equipment needs to be repositioned frequently. Additionally, towable generators often come with enhanced suspension systems that absorb shocks and vibrations, reducing wear and tear and improving overall durability.
They also allow for better maneuverability and can be towed by vehicles such as trucks or tractors, which simplifies logistics and eliminates the need for additional lifting equipment. In contrast, skid mount systems, while stable, generally require a flat surface and may need additional machinery or manpower to move, making them less suited for the demanding conditions of remote or rugged job sites.
IRONPROS: Are there any portable generator accessories that can boost application or use on remote worksites? What are they?
Ranker: Similarly with all equipment, it’s a good idea to have some back-up accessories to ensure one mishap or malfunction doesn’t keep you down for long. Extension cords, load cables, wheel kits, fuel, generator transfer switches and portable maintenance kits may be accessory considerations to keep your team up and running. Keeping extra fuel on hand for remote job sites is a good idea, as well. These accessories collectively boost the generator's efficiency, versatility and reliability, making them indispensable for remote worksites.
IRONPROS: What can customers expect from Bobcat in 2024?
Ranker: 2024 has been an exciting year for Bobcat portable power as it rebranded from Doosan Portable Power to the Bobcat brand. Bobcat portable power products are now available at select Bobcat dealerships throughout North America.
