protected by a barrier at least as high as the cab. The
barrier shall be capable of stopping the weight of the load
capacity of the vehicle if the vehicle were to be stopped

mechanics shall start the motor of, or operate any log or
lumber handling vehicle.
(15) All vehicles shall be equipped with brakes capable
of holding and controlling the vehicle and capacity load upon
any grade or incline over which they may operate.
(16) Unloading equipment and facilities.
(a) Machines used for hoisting, unloading, or lowering
logs shall be equipped with brakes capable of controlling or
holding the maximum load in midair.
(b) The lifting cylinders of all hydraulically operated
log handling machines, or where the load is lifted by wire
rope, shall be equipped with a positive device for preventing
the uncontrolled lowering of the load or forks in case of a
failure in the hydraulic system.
(c) A limit switch shall be installed on powered log
handling machines to prevent the lift arms from traveling too
far in the event the control switch is not released in time.
(d) When forklift-type machines are used to load
trailers, a means of securing the loading attachment to the
fork shall be installed and used.
(e) A-frames and similar log unloading devices shall have

loads above operator's head shall be equipped with overhead
protection.
(g) Unloading devices shall be equipped with a horn or
other plainly audible signaling device.

or cores shall have tusks or a similar type hold down device
to prevent the blocks or cores from rolling off the forks.
(17) Where spinners are used on steering wheels, they
shall be of the automatic retracting type or shall be built
into the wheel in such a manner as not to extend above the
plane surface of the wheel. Vehicles equipped with positive
antikickback steering are exempted from this requirement.

openings shall be guarded.
(29) Guarding lower landing area. The lower landing area
of stackers and unstackers shall be guarded by enclosures that
prevent entrance to the area or pit below the hoist platform. Entrances should be protected by electrically interlocked
gates which, when open, will disconnect the power and set the
hoist brakes. When the interlock is not installed, other
positive means of protecting the entrance shall be provided.
(30) Lumber lifting devices. Lumber lifting devices on
all stackers shall be designed and arranged so as to minimize
the possibility of lumber falling from such devices.
