Street Sweeper Body and Hopper Repair Serving Placentia

Dump hinge bosses wear oval and the hinge pins knock. Once that happens, the hopper no longer lifts square, one side leads, and the resulting twist works the hopper body shell and the lift cylinder mounts. We bore, sleeve and reweld the bosses and replace pins rather than oversizing a pin into a worn hole.

Hopper floors and lower sidewalls corrode from the inside because they are wet with abrasive debris for most of the working day. We cut out corroded sections, replace with plate matched to the wear environment, and weld continuous seams so water does not sit in a stitch weld gap and start the cycle over.

Lift cylinder mounts and the hopper-to-chassis mounting get checked at the same time. A hopper that has been lifting out of square for months has been putting off-axis load into those mounts, and cracks there are common on higher hour units.

Gutter broom arms and main broom mounting take direct curb strikes. Bent arms, cracked mounting brackets and worn pivot bushings all change broom contact pattern, which is why an operator reports the unit is no longer sweeping clean. We straighten, replace cracked sections, and reinforce mounting where the design keeps failing in the same spot.

Water tanks, spray bars and the plumbing between them corrode and chafe. Spray line routing that rubs on a frame member will wear through, and a nozzle that has been fed by a partially blocked line for months will have caused dust complaints on the route. We repair tank mounts, reroute and secure lines, and correct corroded fittings.

On regenerative air units, the suction hose, blast orifice and conveyor components wear from the inside out. We replace hose sections, repair conveyor structure and mounting, and check the pickup head geometry, because a pickup head sitting at the wrong angle sweeps poorly no matter what condition the brooms are in.

Chassis corrosion on a sweeper is concentrated at frame crossmembers, tank straps, air and hydraulic line clamps and any bracket that traps water. Placentia area sweepers running curb and gutter routes see this constantly. We cut back to sound metal, replace brackets, and coat with a system chosen for continuous wet exposure rather than a general fleet primer.

Dual steer cabs add their own damage set. A right hand station used for curb work means the right side of the cab, mirror, glass and door see far more contact and wear than the left, and the second control station itself is subject to damage that a single station truck never sees.

Low-speed impact is chronic rather than dramatic. A sweeper accumulates dozens of small curb, bollard and parked-car contacts over a service life, and it usually arrives here with two or three of them layered on top of each other. We document the whole picture rather than repairing only the newest dent.
