Frequently Asked Questions

General

How much does the MULE cost?

This is question has no single answer. MULES are sold mainly through dealers.  Each MULE has variable configurations depending on customer needs and job site requirements.  Configuration variables can include type of scaffolding attachments or mast attachment options for ground installation, as well as type of grippers that may be most relevant.  Contacting your dealer with specifics will allow you to obtain a detailed price.

Is financing for MULES available?

Financing is available. CR works with third parties that will evaluate the best options for you.

Are MULES available for rent?

CR has numerous dealer partners across the United States, with expanding options internationally. Dealers would facilitate MULE rentals.

Does a MULE have a warranty?

New MULES are covered by an 18-month manufacturer warranty.

Can you help me design the right solution?

If you’re able to join on a Zoom call or Google meeting, we’ll send you an invite and we can review more jobsite use-cases and answer any other questions you may have also.

What is the ROI?

We have customers recognizing up to a 2-3x increase in production! The MULE reduces insurance premiums, workman comp claims, and can support 32″ block and other large materials.

Specifications

How much does a MULE weigh?

The base MULE is comprised of a core section which includes the arm and power pack.  This typically weighs 870lbs.  Each additional component or accessory will add weight.  These weights can be found in the CR Parts Guide.

What are the dimensions of a MULE?

The typical MULE ML150 or ML135 for ground application is approx. 13ft tall with a footprint of 78in x 66in for the ground plate, with the outriggers extended. Exact dimensions depend on final configuration and application / job site logistics (type of scaffolding, etc.).

What is the reach of the MULE’s arm?

Each MULE ML150 or ML135 has a wire rope with an 11ft run. Depending on your job site specific requirements, the MULE can free stand up to 20ft. It can be raised on masts in a wide range of lengths. Cable extensions are available in various lengths also.

What height can the MULE reach?

Each MULE ML150 or ML135 has a wire rope with an 11ft run. Depending on your job site specific requirements, the MULE can free stand up to 20ft. It can be raised on masts in a wide range of lengths. Cable extensions are available in various lengths also.

What type of power supply is required to use a MULE?

120V AC power is the base option. It is convenient to plug into house power or generators.  International adaptations are available as needed.

What is the lifting potential of a MULE?

Weight capacity includes the gripper plus material.

    • MULE ML135 has a maximum weight capacity of 135lbs.
    • MULE ML150 has a maximum weight capacity of 150 lbs.

How high can you free stand a MULE?

20ft with masts.

What material can a MULE lift?

The standard gripper is designed for CMUs. Multiple grippers are available for the majority of existing materials and applications including foundation block, SRWs (segmental retaining walls), refractory brick, metal panels, concrete form panels and precast stone. CR can also design custom grippers for new materials and new applications.  What are you trying to lift?

Does it have adjustable height?

Yes, MULE is modular with mast sections of various heights. A standard MULE package includes a 5ft mast section and a 2.5ft mast section, but some users choose to use extra mast sections to freestand MULE from the ground. You can add up to 22ft of mast before we recommend using wall ties, and up to 44ft total after wall ties.

Operations

Does a MULE work on A-frame scaffolding?

Yes!

Does the MULE work on a mast climber?

Yes! CR offers accessories to attach a MULE directly to the mast climber deck and can also be attached to the mast climber mast.

Can the MULE be used indoors?

There are no regulations preventing a MULE from being used indoors.  Logistics will dictate the feasibility, including building height clearance, sufficiently wide / tall openings to bring the MULE inside, smooth floor surfaces to allow use of a wheeled cart for moving the MULE as needed.

How do you move a MULE?

Each MULE has multiple pick points for use with a telehandler or forklift. Rigging points allow for slinging a MULE.

How do you transport a MULE between jobs and home base?

Each MULE breaks down into multiple shipping configurations depending on your fleet dimensions / capacity. The ground base serves as its own pallet base.  If no ground base is ordered a typical alternative would be a fork base, allowing self-contained transportation.

How long does it take to set up a MULE?

It depends! Do you have the right tools?  How big is your job?  Seriously, it is hard to give a single answer, but a simple MULE configuration can be set up in as little as 15 minutes with as little as 4 nuts and bolts.  A telehandler or forklift is typically required.

What type of training do I need?

Basic operation requires little training for standard operator usage. CR training allows planners and end users to optimize the MULE’s contribution to your process and workflow.  Training is helpful to ensure maximum benefit to increase safety and productivity on the jobsite by incorporating best practices.

What kind of attachment does it take to safely use it on scaffolding?

We have special deck straps designed for MULE to securely mount to mast-climbing work platforms and have approvals from Hydromobile, EZ Manufacturing, Benu, and others. Other contractors have secured the MULE to deck planks on traditional scaffolding or crank-up with a tensioning strap or chain.

Can it be mounted to a buggy for ground use?

Yes, we have a roll-a-round MULE Cart specifically for this application. MULE wheels into place and then outriggers are set.

Can it be used in traditional pipe-frame staging and moved from level to level, or does it require a non-stop style of staging with no deck above?

It can be used on pipe-frame scaffolding, but you must be sure that it is secure, safe, and stable. Also make sure that the MULE is free to swing and work the whole wall section without the arm hitting any cross braces (so top level is best).

Can it be moved around with a Lull?

Yes, MULE comes with fork pockets designed for safe easy picks from front, back, or either side.

Maintenance

What are the maintenance requirements for a MULE?

Maintenance programs will be detailed based on your specific MULE components.  Ongoing maintenance is generally minimal and includes some wire rope lubrication and cleaning fan filters.  Specific annual maintenance requirements can be completed by your mechanics after they are CR verified or by a CR field representative.

What sort of regular maintenance issues could we expect to encounter?

Maintenance is actually pretty minimal since the MULE is outdoor weather rated and built rugged for the jobsite, however, monthly service PM would include lubricating the wire rope, and changing compressor filter, etc. I have attached a copy of the daily-weekly-monthly inspection and maintenance sheet.
