                                                        From Cattron-Theimeg, Inc.

 The Two-Step Electro-Hydraulic Brake Package
 makes converting an Electric Overhead Traveling       Electro-Hydraulic
 (EOT) Crane from cab control to radio remote or       Brake Package
 pendant control easy. The conversion requires         for Cranes
 changing the operation of the bridge brake from
 a foot pedal to an electrically operated brake.
 With the Two-Step Electro-Hydraulic Brake
 Package, the existing foot pedal system remains
 in place, and there is no need to re-size or change
 the existing manual brake system. This eliminates
 the chance for error in sizing a totally new brake
 and potential damage to the mechanical structure
 of the crane during installation of the new brake.
Additional Features
                     Brake Package Features

• Cost Effectiveness: Bypasses the intermediate pneumatic step used on some current braking
  systems, thus reducing cost and improving reliability without sacrificing safety.
• Single Panel Mounting: The brake assembly, minus the motor and pump, is mounted on a single
  panel, in a pre-wired, plumbed, and tested NEMA 12 enclosure. Only three (3) hydraulic connections
  are required for a complete installation. An optional NEMA 4 or NEMA 4X (IP66) cabinet is
  recommended for severe environments (acidic fumes, salt water, etc.) to further guard against
• Step- Down Transformer: All AC systems operate on 110 volts; therefore, the appropriate step-down
  transformer is provided as part of the system when requested.
• Shuttle Valve: All BP 102 and BP202 brake packages work in conjunction with the manual foot brake
  existing on a crane. The manual system must remain operational; therefore, a hydraulic shuttle valve
  is included to automatically select either foot pedal operation or radio operation, without interaction
  between the two.
• Pressure Gauges: Two pressure gauges are provided to monitor the brake cylinder line and pressure stored.
  This allows ease of adjustment and a visual indication of the different increments of braking while monitoring
  the system operation. The second gauge shows the stored charge in the accumulator, which must be present
  to stop the crane in case of pump failure.
• Filter: A spin-on, in-line brake fluid filter is built into this system to catch any small amount of debris which
  would cause possible valve failures. This filter is easily disconnected and cleaned without disturbing system
  piping. It has a service gauge to indicate when the filter should be replaced.
• Custom Valve Manifold: A specially designed, single block manifold for significantly reducing the amount of
  pipes, fittings, and hoses, and increasing reliability and ease of maintenance.
• Portable remote or Pendant Conversion: The BP 102 and BP 202 Electro-Hydraulic Brake Packages can be
 used for converting an existing EOT to either a portable remote control or pendant control operation.
• Temperature: All parts used in the Two-Step Electro-Hydraulic Brake Package can withstand temperatures
  at or below 158ºF (70ºC). Both the valves and the motor have been rated at that temperature for continuous
  operation. This means that the brake system is operational for cranes used above furnaces and in other high
  temperature environments where the ambient temperature does not exceed 158ºF (70ºC). Outdoor operations
  are good at low temperatures because there is no air compressor and no frozen water that is inherent with
  electro-pneumatic systems.
• Pressure Release Valve: This provides an easy method of releasing fluid from the brake panel after transferring
  from radio to manual operation. It also simplifies maintenance; the valve is electrically operated and normally
  ties into a remote/manual selector switch.
• Accumulator: The accumulator is a storage device which will provide a source of pressure should the pump
  become inoperative. The pre-charge inlet requires no special tools to apply pressure or to check the pre-
  charge. It has a special stirred valve (like that on an automobile tire), making a tire pressure gauge all that
  is required to check the pre-charge pressure.
• Brake Fluid Compatibility: All components are designed for use with DOT-3 brake fluid, the type suggested
  by the manufacturers of most existing and new manually-operated foot pedal type brake systems.
• Multiple interfaces: The Two-Step Electro-Hydraulic Brake Packages interface directly to a variety of control
  applications. They can be used on any remote control crane, and with multiple voltages, such as 110, 220
  and 440 VAC or 250 VDC. A user can upgrade an existing crane at any time and can easily interface into
  any portable remote control or pendant system.

Available configurations:

• 110 VAC, 2-step brake
• 220/440 VAC, 2-step brake
•250 VDC, 2-step brake
•110 VAC, 2-step brake plus parking release
• 250 VDC, 2-step brake plus parking release
                           Brake Package Features

    Two-Step Electro-Hydraulic Brake Packages are designed to be installed in parallel with an existing manually
    operated, cab-mounted, hydraulic foot brake. Several available configurations allow for use with a variety
    of crane power sources, such as 110, 220, and 440 VAC, and 250 VDC. Brake operation can be controlled
    by any Cattron-Theimeg Portable Remote Control systems, as well as by pendant. The standard brake
    package offers two (2) adjustable steps of brake application and a brake release function, thus providing
    the operator with precise control of the crane brakes without unnecessary load sway due to abrupt stopping.
    A parking brake release function for a Wagner™ HM parking brake is optionally available (PKK) model.
    An optional three (3) step package is also available by special configuration of the PKK brake model.

    The Two-Step Electro-Hydraulic Brake Package is adjustable and can be tailored to meet your crane size,
    load size, and stopping distance requirements. The system includes a long-life hydraulic pump, driven by
    a continuous duty electric motor. The pump develops the required brake pressure; the pressure is then held
    in the accumulator storage chamber, where it is ready for application to the brake cylinder upon command.
    When applied to the brake cylinder, the pressure varies, depending upon which electric valve is actuated
    and its associated pressure relief setting.

    Each step of braking is independently adjustable to correspond directly to the operator’s stopping rate
    requirements. The amount of brake application pressure is selected by the portable remote control or
    pendant operator. Normally, a soft brake is automatically applied when bridge control is brought to neutral.
    When faster stops are required, hard brake pressure is selected with a push-button on the portable remote
    or pendant remote.

    When properly installed and interfaced with the crane’s control circuits, the brake systems will not permit
    the movement of the crane unless brake pressure is above a minimum level necessary to stop the crane.
    Any loss of power applies accumulated brake pressure to the brake cylinder. This provides brake pressure
    even when the crane power is turned off.
