Cal. Code Regs. Tit. 8, § 1605.9 - Hoist Platforms and Cages
(a) Workmen shall be prohibited from riding
the hoist platform except for authorized inspection and maintenance.
(b) When wheelbarrows or other rolling
equipment are transported, they shall be held securely in place on the hoist
platform.
(c) Overhead protective
covering of two-inch planking, ¾ -inch plywood or other solid material
of equivalent strength shall be provided on the top of every material hoist
cage or platform to prevent objects falling on the workmen loading or unloading
the hoist.
(d) The protective
covering on the top of the cage or platform may be made in hinged sections that
may be raised when hoisting long material.
(e) When using a cage or platform for long
material, the several pieces of the material shall be securely fastened
together and made fast to the cage or platform, so that no part of the load can
fall or project beyond the sides of the cage or platform.
(f) Platform floors covered with metal, shall
have a non-slip surface.
(g) When a
hoist tower is not enclosed, the hoist platform or car shall be totally
enclosed (caged) on all sides including the roof, for the full height between
the floor and the cage top. The walls of the cage shall be constructed of
½ -inch mesh of No. 14 U. S. Standard gage wire or the equivalent. The
hoist-platform enclosure will include the required gates for loading and
unloading.
(h) A stamped plate
indicating the manufacturer's rated load of the hoist in pounds shall be
conspicuously displayed in the hoist cage.
(i) Broken-rope safety devices, if and when
used in conjunction with material platforms or concrete buckets, shall conform
to the following conditions. However, under no circumstances shall they be
construed to satisfy the requirements of Section
1604 of these Orders.
(1) The safety device when engaged shall be
capable of stopping and holding the platform or bucket with its rated
load.
(2) The safety device shall
be securely attached to the frame of the platform, or bucket, in such manner
that the platform, or bucket, will not become separated from the safety device
under the conditions cited in (1) above.
(3) Any platform, or bucket, used in
conjunction with safety devices shall be capable of meeting the conditions
cited in (1) above without resultant failures or loss of its load.
(4) Any material hoist structure including
tower components, guide rails, and their attachments, and any parts affected by
the action of the safety device, when subjected to the conditions cited in (1)
above shall sustain the platform or bucket with its rated load without
structural failure.
(5) The safety
device shall be activated by a positive means in the event of rope failure, and
when engaged shall be released only by raising the platform or bucket from the
stopped position.
(6) The ability
of the equipment to satisfy the requirements of (1) and (2) above, shall be
established by tests witnessed by the enforcing authority, an independent
testing laboratory, or registered professional engineer.
