Cal. Code Regs. Tit. 8, § 1605.14 - Hoisting Machines
(a)
Hoisting machines shall be designed, installed, and maintained to vertically
raise and lower the rated load plus the weight of equipment and
ropes.
(b) The hoisting machine
shall be equipped with brakes capable of stopping and holding 125 percent of
rated hoisting capacity under all operating conditions.
(c) The hoisting machine shall be secured in
position so as to prevent lateral movement, shifting, or
dislodgement.
(d) The location and
arrangement of the hoisting machine, tower, and related sheaves shall be such
that proper wrapping of the wire rope on the drum will be assured to prevent
"overriding," fouling, improper spacing, or any other condition which will
cause damage to the wire rope or hoisting machine.
(e) Hoisting machines shall not be left
unattended with the load suspended.
(f) Adequate blocking and bracing shall be
provided between the hoisting machine and the tower to prevent the transmission
of any unbalanced lateral forces to the tower resulting from the pull of the
hoisting ropes.
(g) When hoisting
machinery is set on an elevated platform, such platforms shall be of
substantial construction, properly engineered, and provided with guardrails and
toeboards which conform to these Orders.
(h) Wire hoisting ropes within 7 feet of
floor or ground shall be guarded by an enclosure or fence.
(i) All gears on hoisting machines shall be
completely guarded.
(j) Not more
than one platform winch head, boom, or bucket shall be operated at the same
time by any one hoisting machine.
(k) Brake drums shall be kept free of oil,
grease, or any other substance which reduces their efficiency.
(l) Mechanical brakes shall be so installed
as to stop movement of the winding drum, and equipped with a positive acting
latch or other mechanical device, designed as part of the hoist, which will
hold the brake in the engaged position.
(m) Each manually operated hoisting machine
shall be equipped with an effective pawl and ratchet capable of holding the
rated load capacity when it is suspended.
(n) Internal-combustion-engine exhaust pipes
shall be arranged to exhaust away from workmen so the gases will be dissipated
harmlessly. A muffler shall be installed to reduce the noise.
(o) Only approved safety cans shall be used
for fueling internal-combustion engines. When gravity-type fuel systems are
used, a cutoff valve shall be installed between the internal-combustion engine
and the fuel-supply tank.
(p) Open
light, flames, or spark-producing devices shall be kept at a safe distance
while refueling internal-combustion engines, and no person shall smoke or carry
lighted smoking materials in the immediate area. The engine shall be stopped
during refueling.
(q) A fire
extinguisher which meets the requirements of the General Industry Safety Orders
shall be part of the hoisting equipment.
(r) The operation of every hoist shall be
controlled by an electrically or mechanically designed signal system. Manual
signals may only be used when visibility and distance permit, and the signals
can be relayed directly to the hoist operator. See Section
1605.21 for recommended signal
systems.
(s) The platform, cage, or
bucket shall be brought to its lowest position, the hoisting machine shall be
shutdown and positively secured against accidental start-up when men climb the
hoist tower or work on any part of the tower below the cathead. The platform,
cage, or bucket may be used to raise workmen for authorized maintenance and
repairs that cannot be done otherwise.
(t) All hoisting equipment, including brakes,
gears, levers, and wire rope, shall be visually inspected daily. All broken,
worn, or defective parts shall be repaired or replaced when
discovered.
(u) Electrical
equipment shall be effectively grounded. Ground cables shall be enclosed or
shielded as necessary, and shall be tagged for identification.
(v) Each automatically operated
electrical-motor-driven hoist shall be provided with a mechanical automatic
motor brake, or equivalent device, to hold the load automatically in case of
power failure.
