Dealer/End User/Supplier  There is no real clear line

One of the biggest challenges CWS suffers from is putting together a package of services that suits every dealer or end user. Differing capabilities between dealers and between end users, make it impossible to package a common solution for every circumstance. Where one dealer has a capability to design and install a complete hydraulic system in a machine, in house, and jealously guards the shop hours this work produces, the next has no capability and wishes that every attachment would come installed or at least with valves, hoses, fittings and step by step instructions to connect it all.

Generally the end user just wants a working combination of machine and attachment to be delivered to his jobsite ready to work. But even here, there are exceptions where some end users have extensive shops to cater to their own unique requirements and choose to do their own machine modifications.

Who Does What?

CWS offers a variety of attachments suited to many of the common types and brands of Heavy Equipment. Our generic listing is not intended to make recommendations about the type, brand or size of machine to do any job. It is up to the O.E.M. or the dealer to study an application and recommend the type and size of machine. Once a machine is chosen for the job, CWS personnel can recommend some typical attachments and to make a technical recommendation, we must know the following:
  • Weight per unit of payload
  • Required rate of production
  • Operating environment; temperature, elevation, humidity, availability of service to the site
  • History of successes of failures of other machines in the application
  • Unique characteristics of the machine contemplated for the job. That is when it is not a standard version such as when it is a; "Forestry"; "High Lift"; "Mass Excavation"; "Heavy Lift"; "Special Application"; "Short Boom"; "High Horsepower"; "Extra Counterweight"; version.

The more we know up front, the more precise our recommendation can be

Although we have extensive capabilities to design custom hydraulic connection packages, in practice our most common package is a "Standard Attachment". We have five levels for potential involvement in mounting and connecting an attachment. These are:
  1. Standard Attachment only which includes the weldments and any; hinge pins, bushings, bolts, hydraulic motors, cylinders, fittings and hoses within the attachment itself.
  2. Standard Attachment with optional extra "jump hose kit". Due to the thousands of different machines we must connect to, there is a limited array of "machine specific" kits available.
  3. Standard Attachment with optional "jump hoses" plus lines to route inside the machine to an existing hydraulic power supply.
  4. Standard Attachment with a "Custom Install Kit" including all hoses, fittings valves, pumps, and instructions. (Note: limited availability)
  5. Standard Attachment and Custom Install Kit installed in one of our facilities.
Additionally, our engineers are available to help in two ways:
  1. To Assist with Adapting a New Attachment to a Machine (no fee)
    Within reason, this is a no cost service to our customer's when a new attachment has been purchased. Help is usually by phone, fax or email using our practical experience to solve compatibility problems between the customer's machine and the IMAC Attachment during a first time installation as follows: -
    1. Adapting and setting the customers hydraulic system to properly operate an IMAC Attachment.
    2. Setting up stops to properly limit the amount of articulation of an attachment on the machine.
    3. Recommending additions or modifications to standard attachments to make them more suited to the application.
  2. As consultants, (for a fee and expenses where applicable)
    This service can include site visits, component specification and supply if necessary, and even supervision of a client's workers if asked to do so. Often our designers will involve the installing dealer's personnel and work with engineers at the major OEMs to insure the final design us compatible with machine. They are available for the following types of consulting work: -
    1. To design hydraulic circuits to operate IMAC Attachments on nearly any machine.
    2. To predict performance to be expected of a machine/attachment combination in a customer's application. Work can include static tip analysis, production studies and developing new attachment concepts for unique applications.
    3. To design modifications to the OEM. machine to make it more suited to a unique application.
INCLUDED with a Standard CWS Attachment
Unless stated otherwise, IMAC's "standard attachment" package consist of the following:
  • Weldments that make up the attachment including connection points compatible with known OEM. machines and their standard attachment mounting hardware.
  • Built in hydraulic cylinders, motors, rotary manifolds and mechanical parts that are an integral part of the interworking of attachment parts.
  • Built in hydraulic fittings, hoses and hard lines necessary to interconnect hydraulic components and terminate them at a manifold point within the attachment. Generally the manifolding point is located for compatibility with supply line routing from the carrier machine.
  • Hydraulic schematic, or specifications, or a combination of the two, suggesting the flows and pressures needed to operate the attachment in average conditions.
  • Parts book

INCLUDED with a Standard CWS Attachment
  • Mounting pins, trunnions, bolts or other intermediate hardware and parts that are necessary to connect the IMAC attachment to the machine proper. For example:
    • Trunnion balls for connecting dozer push groups to tractors.
    • Hardware and linkages that adapt the machined bores on the back of dozer blades to the push arms of tractors.
    • Pins, bushings and locking mechanisms for mounting attachments to loader arms or excavator booms.
  • Hydraulic Jump Hoses to connect from the OEM.'s termination point to the back of the attachment.
  • Pumps, valves and fittings to add extra circuits within a machine for supplying attachment functions.
  • Design work for modifying the OEM machine to accommodate an attachment.
