Spydercrane URW546

URW 546

Similar in size to the URW376, the URW546 gives you a more powerful mini crawler crane in the same amount of space. Lift nearly 4 ½ tons with stability and precision, even on rough terrain!
  • Maximum Lifting Capacity 8,920 lbs. @ 8 ft.
  • Working Radius 2.2 ft. to 50.9 ft.
  • Fits Through Double Doors
  • Dimensions (W x H x L) 4.52 x 6.67 x 16 ft.
  • Weight 11,155 lbs.
  • Engine Options Diesel or diesel/electric


Like the URW376, the Spydercrane URW546 mini crawler can lift its maximum load up to 8 ft., and has a tip height similar at 53 ft. However, the URW546 gives you 37-38% more lifting power than either of our smaller mini crawler crane models, and still folds to a slender 4.52 ft. to fit easily through a set of double doors! Depending on your choice of diesel or electric motor, the URW546 can put out between 10 and 24 HP and either engine can produce speeds between 1.86 and 3.92 MPH. Its boom lift speed is 0 to 80 degrees in 18-25 seconds. Like all Spydercranes, this model offers 360 degree continuous rotation and can be operated from its work platform, or by remote control, providing maximum flexibility for operators. Another Spydercrane standard, infinitely variable controls, allow for multiple functions to take place simultaneously. All of this power is balanced by an impressive array of safety features.

Compact Design

If good things come in small packages, then incredible things come in the Spydercrane URW 546. A maximum lifting capacity of 8,920 lbs. @ 8 ft. yet compact enough to fit through Double Doors when in transportation mode, the URW 546 provides unparalleled efficiency when working in confined spaces. Even more incredible, experienced operators can go from travel to expanded position in around 5 minutes.

Versatile Outrigger Configurations

The Spydercrane URW 546's unique design allows each leg to be adjusted independently. This allows for the crane to work fluidly on uneven surfaces. Multiple-leg extension and angle positions means most obstacles are not an obstacle to setup.

Standard Radio Remote Control

Each Spydercrane comes with infinitely variable controls which allows for simultaneous, multiple functionality. For those who would rather navigate outside the crane, Spydcrane's standard radio remote control allows for increased operator usability & flexibility. With the radio remote, operators are given controls such as multiple speed selections, automatic throttle activation, emergency shut-down and a pressure sensitive trigger for speed control.

Excellent Working Radius

The Spydercrane 546 provides 360-degree continuous-rotation boom, allowing for safe lifting even when the outriggers are set to maximum position. This working radius allows for loads to be lifted to the center line of rotation.

Turn-Over-Protection System*

Just like its fellow Sypdercranes, the URW 546 comes standard equipped with advanced Turn-Over-Protection System. This safety feature automatically restricts crane functions and sounds an alarm to help reduce the chance of injuries and crane tipping. The Turn-Over-Protection System monitors the ground-bearing pressure at each outrigger regardless of the configuration.

*Crane operators need to be aware of the load weight and lifting limitations and shouldn't rely on the crane's safety functions to prevent accidents.

Anti-Two Block System

Spydercrane URW 546's Anti-Two Block System warns operators when the hook reaches the maximum safe height, thus eliminating overhoisting damage at the boom. The system also features a function lock-out which stops further forward travel, reducing the chances for damage or injury.

Onboard Self Diagnostic System

To provide constant updates to the crane's operating status, the Spydercrane URW 546 is equipped with an Onboard Self Diagnostic System. The system's current operation mode is conveniently located on the side of the control box. With the Onboard Self Diagnostic System, the crane will help itself reduce downtime.

Hexagonal Boom Design

In order to greatly reduce sway, increase accuracy and safety in crane operations and provide increased rigidity, the Spydercrane URW 546 is designed with a Hexagonal-Shaped Boom.

Additional Safety Features

As an industry leader in mini crane safety, the Spydercrane URW 546 comes loaded with additional safety features. These features include a minimum rope automatic stop, automatic hook stow system, hook safety latch, hydraulic circuit pressure relief valve, bubble-style level for outrigger leveling, hook safety latch, and over-winding prevention device and alarm.

Powr-Grip® Glass Handler

All Spydercranes work with several models of Powr-Grip vacuum lifting systems, lending strength, stability and control to the movement and installation of even the largest of glass panels. The URW546 gives you the power to raise buildings and the precision to make them out of glass.
