What is a “SPYDERCRANE” mini-crawler?

A “SPYDERCRANE “ mini-crawler is a mini-crane that has been designed and built for working in low access confined areas either indoors or outdoors. It is mounted on a dual track chassis with “spider-type” legs for its outriggers. The SPYDERCRANE will go where a conventional truck mounted crane or carry deck crane will not have access due to its size.

Who makes the SPYDERCRANE?

The SPYDERCRANE mini-crawler mini-crawler was designed, developed, and is manufactured by Furukawa UNIC, a Japanese company that has the largest distribution and production of hydraulic cranes in the world. Furukawa UNIC is the inventor and pioneer of the mini-crawler crane.

Who is Furukawa UNIC?

Furukawa UNIC is a Japanese company that has been producing hydraulic equipment since 1946. They are the largest manufacture of hydraulic cylinders and cranes worldwide. Furukawa UNIC is the largest manufacturer of truck mounted cranes and mini-crawlers.

How long has the SPYDERCRANE been in the United States?

The UNIC SPYDERCRANE was first developed 30 years ago and has been widely used in the Asian market and European market for this time. It was first introduced into North America (United States and Canada) by Smiley Lifting Solutions in 2006.

What size SPYDERCRANE do I need?

With so many different sizes of cranes it can be hard figure out which one is right for you. Call us at 623-269-9000 to speak with one of our experienced staff to help you make the proper crane sizing decision for your job and location.

Are there training requirements or special certifications for my operators before they can use a SPYDERCRANE?

Due to the nature and size of the SPYDERCRANE there are generally no special qualifications to operate the mini-crawler. However, upon delivery of your SPYDERCRANE, our delivery experts will familiarize your operators with the function and controls of the crane. Also, our support staff is only a phone call away if you have additional questions throughout your project.

Do you have a location that is close to my jobsite?

Yes, our mini-cranes are available to rent anywhere in North America. Please call us to find out our logistical capabilities.

What safety features are SPYDERCRANEs equipped with?

All UNIC SPYDERCRANEs are considered the safest cranes in the market because of the safety features we include as standard equipment. The standard safety features include: UNIC patented “Over-Turn Protection System”, LMI-Overload Protection, winch cable over winding prevention device, minimum wire rope on drum prevention device, automatic hook stow system, hook safety latch, anti-two block system, an on-board self-diagnostic computer system, voice messaging.

What is an “Overturn Protection System”?

Overturn Protection System is a patented UNIC exclusive safety device that is included on the SPYDERCRANE URW094, URW295, and URW306 models. There is no other crane that can offer this state-of-the-art safety device. It is a far superior system compared to a common LMI System. The Overturn Protection interfaces with the on-board computer system and continually measures ground pressure on each outrigger, through a “load cell” on that is incorporated into each outrigger. When one outrigger starts to lose ground pressure, an alarm sounds and the mini-crawler will start to de-rate itself and slow the crane functions. When two outriggers start to loose ground pressure, the crane will stop all functions that would put the crane into an unsafe position. With the alarms sounding and the crane stopped, the operator will now be able to position the crane back to the safe mode. An LMI-overload system will not stop the motion of a crane when an outrigger is sinking into lose ground, the UNIC Overturn Protection will shut the crane down.

Does the SPYDERCRANE have various engine/power options?

Yes. Depending on the SPYDERCRANE model you choose, you will have a choice of; battery 110V power, gasoline, propane, diesel, 220-480V single phase and 3 phase electric, or a combination of power such as gasoline/propane/220V electric all on one machine. The battery powered mini-crawlers will last up to 8 hours on a full charge and can be plugged into a common 110V wall outlet for operation and charging of the system.

Do the SPYDERCRANE engines meet all current EPA Tier 4 requirements?

Yes. All SPYDERCRANE mini cranes distributed in North America are built to meet current EPA standards and regulations.

Do the SPYDERCRANEs meet North American crane regulations?

All SPYDERCRANE models distributed in North America are manufactured to all current standards and regulations. This includes ASME B30.5 and CSA Z150 compliance standards, which applies to all mobile cranes. OSHA regulations require conformity to ASME B30.5.

Is there a remote control available for the SPYDERCRANEs?

Yes. All SPYDERCRANEs except the URW306 model are equipped with a wireless four-function radio-remote control system. The remote has an operating range of a 300 ft. radius. The system operates on a 15 channel frequency, which makes it impossible for any type of interference. Critical work environments such as Military aircraft facilities and Nuclear Power stations use this proven system without any interference with radar. This wireless remote control is standard on all SPYDERCRANEs.

Can a work basket or personnel basket be used on a SPYDERCRANE?

Yes. The work baskets are designed specifically for the SPYDERCRANE. Each basket is designed and manufactured to current North American standards and regulations. They are made of a lightweight Chromalloy steel and easily attach to the boom tip of the mini-crawlers. When used in conjunction with the wireless remote control, you now have a “man lift”.

Can the outriggers on a SPYDERCRANE be set-up in various positions?

Yes. The URW094 has a total of 62 possible outrigger positions and the URW295 model has a total of 52 possible outrigger positions. SPYDERCRANE mini-crawler cranes are the only available cranes with this feature. This is possible because of the patented Overturn Protection system. Due to the fact that all other cranes are equipped with the limiting and un-advanced LMI-overload system, it is impossible for them to achieve this highly usable outrigger positioning feature. With the advanced outrigger positioning system, the SPYDERCRANE can virtually set-up and operate in any tight confined work environment.

Do you have a rent to purchase option?

Are you thinking about renting a crane for your next project, but not sure that you’ll want to continue renting a crane over an extended period of time? Our Rent-to Purchase plan allows you rent the equipment that you need with the option to purchase it at a later date, using funds that have been paid in from the rental. Contact SPYDERCRANE today to see how we can tailor a rental package to fit your specific needs.


  • Erecting steel in a construction setting can be a grueling process. It can be quite difficult to navigate a traditional crane in such areas. Situations such as these are perfect for a SPYDERCRANE, as it can easily maneuver in tight areas. When compacted, our SPYDERCRANE mini-crawlers are able to travel through an entry as narrow as a standard doorway, yet expand to provide a lifting capability of up to 13,200 pounds. ​VIEW ALL SPYDERCRANES

  • The SPYDERCRANE lineup of Mini-Crawler mini cranes is an ideal solution for performing aviation maintenance tasks. Our SPYDERCRANEs are used regularly in many aviation facilities for the assembly and maintenance of planes and helicopters. ​VIEW ALL SPYDERCRANES

  • The mechanical industry can create some of the smallest and tightest work areas. Areas that are so tight, no ordinary crane can reach them. The SPYDERCRANE is engineered to fit into small areas, allowing you to work more efficiently. When compacted, our mini-crawlers mini cranes are able to travel through an entry as narrow as a standard doorway, yet expand to provide a lifting capability of up to 13,200 pounds. ​VIEW ALL SPYDERCRANES

  • Whether it’s a commercial project or a large-scale construction job, the glazing industry is synonymous with lifting large and heavy panes of glass. In recent years, the glazing industry has discovered how versatile and useful a SPYDERCRANE can be.
