1 CHASSIS ENGINEERING GUIDELINES (ISSUE A, AUGUST 2018) DESIGN GUIDELINES FOR: FUSO HD 8x4 MODELS: FS52SS, FS54SS APPLICATIONS - FLAT DECK, CURTAINSIDER, TIPPER, LOGGER These recommendations have been prepared for design engineers and body builders as a guide to assist when selecting and specifying chassis modification and/or body fitment. These guidelines should be read in conjunction with the Mitsubishi Fuso Truck & Bus Body Equipment Mounting Directives available on the FUSO Body Builder Portal. Use these guidelines to determine any reinforcement details required for each application. LOAD CONSIDERATIONS CHASSIS FRAME MATERIAL FLAT DECK U.D.L. CURTAINSIDER LOAD CENTRE TIPPER AT LIFT OFF AT MAX TIP LOAD CENTRE SPREADING Consider as a uniformly distributed load over whole or part of deck length. Consider as a uniformly distributed load over whole or part of deck length in conjunction with point loads imposed by body and taillifts. Determined as water level load 600mm above chassis. Point when body raised just clear of the chassis thus imposing two point loads on the chassis rails at hinge and hoist mount. Point when the body is raised to tip angle of 48, (tail door closed) so loads act at the hoist mounting and hinge pivot points. Determined as water level load 600mm above chassis. Spreader work imposes higher frame loads and may require chassis reinforcement. Hot Rolled Steel, 540 MPa tensile, 380 MPa yield. MAXIMUM DESIGN STRESS Recommended maximum design stress = 35%* of chassis yield stress (133 MPa) for sections of frame that are unmodified or do not contain stress raisers. Appropriate allowance should be made for details in the frame that have been modified or contain stress raisers. Refer to the body builders manual for stress levels using static load applications. For heavy duty, more arduous applications, eg., sidelifter, the stress levels should be reduced a further 33% to enhance frame durability. Recommended heavy duty design stress = 2/3. Recommended max design stress = 90 MPa. CASE 1 CASE 2 MAXIMUM CHASSIS DEFLECTION Between front and rear axis. Maximum permissible deflection: ±8mm. Rear overhang. Maximum permissible deflection: 15mm at 1000mm or greater, rear of rear axis. LOGGER LONGS/SHORTS Consider as a point load applied through bolster mounting positions. Use Bolster attachment code. Frame reinforcements should be balanced in terms of frame strength. Bolster mounts of an appropriate size and shape could contribute to the total frame strength. This specification sheet applies to vehicles supplied by Fuso NZ for the New Zealand market. REF: J22974 / S-HDEURO5SUA.DWG Copyright Fuso NZ (2018) fuso.co.nz
