[SOLVED] UPS freight calculator

I have managed to get a UPS Shipping calculator working in PHP. I now found out that the standard shipping from UPS is capped at 150lbs. For anything over 150lbs, I need to ship via freight.

Has anyone ever coded a Freight Calculator with UPS? The calculator I wrote for anything under 150lbs does not require a UPS account. I was hoping to do the same for the freight calculator, however, I am unable to find any information on how to accomplish this.

Any help will be greatly appreciated.

EDIT

As per request by Nicolaesse, I have added some code snippets that I wrote in 2009 to solve my problem.

Demo can be seen here: http://cart.jgallant.com (Add product to cart, checkout, and enter zipcode for shipping estimate)

Core UPS class:

<?php
    class ups {

    function getMethod() {
        $method= array(
                '1DA'    => 'Next Day Air',
                '2DA'    => '2nd Day Air',
                '3DS'    => '3 Day Select',
                'GND'    => 'Ground',
            );
        return $method;
    }

    function get_item_shipping($weight, $zipcode)
    {
        unset($_SESSION['zipcode_error']);
        if($weight > 150) {
             $_SESSION['zipcode_error'] = "A cart item requires freight.";
        }
        if (!isset($_SESSION['zipcode_error'])) {
            $services = $this->getMethod();
            $ch = curl_init();
            foreach ($services as $key => $service) {
                $Url = join("&", array("http://www.ups.com/using/services/rave/qcostcgi.cgi?accept_UPS_license_agreement=yes",
                "10_action=3",

                );

                    curl_setopt($ch, CURLOPT_URL, $Url);

                    $Results[]=curl_exec($ch);
            }
            curl_close($ch);
            $pre = "";
            $shipping_list = array();
            foreach($Results as $result) {
                $result = explode("%", $result);
                if ($services[$result[1]] != ''){
                    if ((($result[1]=='XPR') && ($pre == 'XPR')) || (($result[1]=='XDM') && ($pre == 'XDM')) || (($result[1]=='1DP') && ($pre == '1DP')) || (($result[1]=='1DM') && ($pre == '1DM')) || (($result[1]=='1DA') && ($pre == '1DA')) || (($result[1]=='2DA') && ($pre == '2DA')))
                        $shipping_list += array($services[$result[1]."L"] => $result[8]);
                    else if (($result[1]=='GND') && ($pre == 'GND'))
                        $shipping_list += array($services[$result[1]."RES"] => $result[8]);
                    else
                        $shipping_list += array($services[$result[1]] => $result[8]);
                    $pre = $result[1];
                }
            }
        }
        $shipping_list = array_reverse($shipping_list);
        return $shipping_list;
    }
