TramBeam and Louden Systems
Underhung "patented track" cranes using high strength alloy steel track in single and double girder types to 30 tons capacity. Trambeam and Louden cranes can be provided for interlocking applications to transfer loads to another crane or monorail. Patented track monorail systems provide versatile handling that includes switches, lift sections and long life rugged track.

Types of TramBeam and Louden Systems:
TRAMBEAM SINGLE GIRDER
are available for rated loads to 10 tons. They are cataloged as 2-runway cranes with spans to 100′-0″. Longer span cranes with multiple runways are also available. Single girder cranes may be hand propelled, hand racked or motor drive.
TRAMBEAM LOW HEADROOM CRANES
provide maximum lift by framing the bridge girder into the end trucks. These cranes are limited in span and rated load because of the special girder construction. Also, loads cannot be transferred to other cranes or monorail spurs when the girder is framed into the end truck.
TRAMBEAM DOUBLE GIRDER CRANES
are available for rated loads to, 30 tons. They are generally used for heavier loads and longer spans, but may also be used for lighter loads where maximum hook lift is desirable. Double girder cranes are cataloged as 2-runway types with spans to 100′-0″. Longer span cranes with multiple runways are also available.
TRAMBEAM TRANSFER CRANESÂ
provide complete coverage of large areas without re-handling of the load. Interlocking mechanisms on the ends of girders allow loads to be transferred from cranes to monorail spurs or to other cranes. These mechanisms can be either manual or motor operated.
TRAMBEAM GANTRY CRANES
are used where a repeated work operation or a particular work area is of an unusual nature. These cranes can be either single or double girder construction and can be hand propelled, hand racked or motor driven.

EQUIPMENT SELECTION
ANALYZE YOUR APPLICATION
determine the sizes, shapes and weights of loads, frequency of lifts and moves and best method of handling, i.e., crane or monorail.Â
PLAN LOAD HANDLING
determine what below the- hook devices may be needed and the weights of these devices.Â
SELECT HOIST AND CARRIER
hoist is rated to handle the heaviest load plus the weight of any below-the-hook device that may be used.
SELECT CRANE
determine crane catalog number for span and rated load.
SELECT CONTROLS AND ELECTRIFICATION
evaluate operating controls and power supply methods.
SELECT RUNWAY OR MONORAIL TRACK AND SUSPENSION
determine load on track, centers between suspension supports and load on building

WHEEL SPECIFICATIONS
A variety of wheel assemblies are available for the many service conditions encountered in Trambeam underhung crane and monorail systems. Flanged wheels are satisfactory for most applications. Flangeless wheels with side guide rollers are used where an application requires high service factors or where speeds are greater than 200 FPM.
Wheels when assembled into carrier heads can be removed for servicing or replacement without removing the carrier head from the track. Wheels used in carrier heads with one piece yokes have removable axles or the axle is short enough to allow removal.
Wheels are machined from steel forgings and are induction hardened to a 45 Rockwell “C” (425 Brinnell) minimum hardness. After hardening, the bore is finished to the bearing manufacturer’s recommended tolerance. Axles are alloy steel. Rated SECTION: CARRIERS
Bearings provide the minimum B-10 bearing life as stated in ANSI MH 27.1 Specifications for Underhung Cranes and Monorail Systems. Bearing life varies with each application and depends on equipment speed and wheel load; consult factory for bearing life on specific applications. Pregreased bearings are factory “lubricated-for-life”; regreasable bearings are furnished with grease fittings in the wheel axles for periodic lubrication. Bearings are designed for a maximum operating temperature of 150 Deg. F; consult factory for higher temperature applications.
Bronze wheels are available for spark-proofing and operation in hazardous locations; consult factory for recommendations.
Wheel assemblies are illustrated on Page CA-3. Dimensions, rated loads and other pertinent data are listed in the table on this page
