SPB Operation Manual
Frequent inspections
Frequent inspections should be performed by a desig-
nated person at daily to monthly intervals, and should
include observations prior to and during operation.
The designated person should determine whether con-
ditions found during the inspection constitute a hazard
and whether a more detailed inspection is required.
Inspect boom and structural support
• Safety devices, such as holding valves, guards
and interlocks, for proper operation
• Boom controls for proper operation and engage-
ment
• Boom and outrigger hooks, straps, and latches
for proper operation and engagement;
• Hydraulic hoses should be checked during rou-
tine inspections. Check for damage to the outer
layer or fittings. For example; Wire reinforcement
is exposed, separation from the fitting, chafing,
cuts, cracks, brittle outer layer or any other type
of deformation like layer separation, blistering,
crushing, corrosion, or kinking. In addition check
for leaking fittings or improper fit.
Hydraulic hoses should be replaced
every six years to avoid the possibil-
ity of accidental rupture and possible
personal injury. The date of manufac-
ture of a hydraulic hose can be found
stamped into the hose fitting
• Hydraulic oil level
• Hydraulic oil leaks
• Remote control boxes and cables for proper op-
eration, exposed wires, broken controls, missing
control guards, or broken plugs
• Boom and outrigger structures for visible defor-
mations, cracks, and damage
• Boom and outrigger pins for visible wear, dam-
age, and missing hardware;
• Tires for sufficient tread, proper inflation, cuts,
and loose lug nuts;
• Proper loading of accessories to prevent loss
while traveling;
• Proper lubrication of moving parts.

mum material pressure, according to the manu-
facturer’s instructions
• dents or cracks;
• missing locking pins;
• leaking gaskets
Delivery system hoses for:
• internal wear, according to the manufacturers
instructions;
• separation of the ferrule from the hose;
• bulges, kinks, soft spots, cuts, or abraded areas

• presence of hardened concrete.
Couplings:
• cracked, broken, distorted, or missing compo-
nents;
• proper operation of the adjusting nut, if so
equipped;
• concrete preventing proper operation;
• system compatibility.
Separately laid pipeline components for:
• sufficient wall thickness to withstand the maxi -
mum material pressure of the material placement
system, according to the manufacturers instruc-
tions.;
• Dents, holes, or deformed ends;
• the presence of old concrete inside the pipeline.
Cables or slings used to secure hanging system com-
