Part 2 - Products

            2.01 - ACCEPTABLE MANUFACTURERS

                        A. Model FXTM  as manufactured by Kelley Dock Systems, Milwaukee, WI.

            2.02 - EQUIPMENT

                        A. CURB ANGLES: Eight pieces, 3x3x3/16", to cover all exposed edges of

                             pit and forward dock edge as required for bumper mounting.

                        B. LEVELER:

                                    1. RAMP: Reinforced with twist resistant lamda style cold-roll beams.

                                    Torsionally compliant ramp construction to be three sided without header

                                    plate.  Four hinge pins at rear of ramp assembly.  Lug hinges welded

                                    directly to deck and beam front with a minimum of 15 1/2" of weld.

                                    Open lug style lip hinge construction.  Lip hinge to allow swept debris to

                                    fall to ground between lip and hinge pin and deck and hinge pin.  To

                                    include structural full operating range toe guards with Safety Yellow

                                    markings as required by OSHA as per ANSI - Z535.

                                    2. LIP: Hinge pin lugs to be welded a minimum of 3" from rear edge of

                                    lip towards front edge, or provide 4" of lip support under lip from

                                    rear edge.  Lip hinge welds to run parallel to deck reinforcement beams for

                                    added strength.

                                    3. SUB FRAME: 19" deep to facilitate 20", sloped and 24" deep pit

                                    configurations.  Rear portion equipped with four upright members that

                                    form ramp rear hinges.  Side of formed longitudinal angle members to

                                    connect with rear portion of subframe and front dock leveler support

                                    leg and ramp pads.

                                    4. DOCK LEVEL SUPPORT: Two structural formed dock level

                                    support legs at forward end of ramp to be designed to rest on                                                  subframe ramp support pads for increased positioning accuracy. 

                                    60,000 lb. structural dock level support legs - drop tested to the full

                                    rated capacity of the leveler - provide free fall protection. 

                                    5. LIFTING SYSTEM: Ramp powered by low-pressure system,

                                    driven by a two-stage 10 amp fan motor which directs air into bag

                                    subassembly and lifts ramp and lip assembly.  System to be activated

                                    by push-button and include automatic lip extension.

                                    6. ENVIRONMENT: Lifting system to be free from hydraulic fluids

                                    which may potentially harm the environment and surrounding ground

                                    water supplies.
