        <block type="page/html_header" name="header" as="header">
            <action method="setTemplate"><template>page/html/cartheader.phtml</template></action> 
        </block>          
    </reference>

    <reference name="footer">
        <block type="cms/block" name="Shopping Cart" before="footer_links">
            <action method="setBlockId"><block_id>shoppingcart</block_id></action>

Answer 1

Block type is page/html_header not page/header

Change below code

       <reference name="header"> 
            <block type="page/header" name="header">
                <action method="setTemplate"><template>page/html/cartheader.phtml</template></action> 
            </block>
            <remove name="navigation-link"/>
            <remove name="cms_footer_links"/>            
        </reference>

to:

   <reference name="header">            
        <action method="setTemplate"><template>page/html/cartheader.phtml</template></action>            
        <remove name="navigation-link"/>
        <remove name="cms_footer_links"/>            
    </reference>

Answer 2

Try this code

<reference name="header">
    <block type="page/header" name="header">
        <action method="setTemplate"><template>page/html/cartheader.phtml</template></action> 
    </block> 
</reference>

Answer 3

try this with root reference

<checkout_cart_index> 
              <reference name="root">
  <block type="core/template" name="header" as="header" template="page/html/cartheader.phtml"/>
</reference>

        <reference name="footer">
            <block type="cms/block" name="Shopping Cart" before="footer_links">
                <action method="setBlockId"><block_id>shoppingcart</block_id></action>
            </block>        
        </reference>

    </checkout_cart_index>

other solution is

copy app/code/core/Mage/Page/Block/Html/Header.php

to app/code/local/Mage/Page/Block/Html/Header.php

change template in construct

public function _construct()
    {
      $currentUrl = Mage::getUrl('*/*/*', array('_current' => true));
  if (strpos($currentUrl,'checkout/cart') == true) {
        $this->setTemplate('page/html/cartheader.phtml');
  } else { $this->setTemplate('page/html/header.phtml'); }
    }
