Heavy 5-Axle Crane Dolly

We are pleased to present SPARTA ENGINEERING’S new crane dolly design. This dolly is designed as a tandem-tridem axle dolly trailer and made to couple to dedicated cranes. By transferring part of the boom weight off the crane and onto the dolly, it meets legal road weights. The crane boom dolly comes with an oilfield tough construction, powder coated frame and 24 volt electrical system. There are some popular options that set this crane dolly apart from the rest including the rear Jack Pad holder. The rear outrigger or jack pad holder is designed to fit 4 pads between a 36” and 48” diameter at the back of the trailer and comes with an easy-to-use pull out ramp to roll the jack pads into place. The weigh centers are also adjustable and customizable to work with your specific crane weights. Suitable for cranes with 200-300+ ton capacity.

Please keep in mind here at Sparta if our design does not match up with your crane we can work with you to develop a product that will. Be it the wrong pintle length, boom height, or pad size we can design a crane dolly to meet your needs.
