Product Description
steel Painting hook with red color(HX6024)
The following additional features have been incorporated in the new 320A Eye Hoist Hooks. (Sizes3/4 metric ton Carbon through 22 metric ton Alloy.)
• Metric R ated at 5:1 Design Factor for (Carbon Steel); 5:1 Design Factor for 1t - 22t (Alloy Steel).
• Can be proof tested to 2 times the Working Load Limit.
• Low profile hook tip.
• New integrated latch (S-4320) meets the world-class standard for lifting.
• Heavy duty stamped latch interlocks with the hook tip.
• High cycle, long life spring.
• When secured with proper cotter pin through the hole in the tip of hook, meets the intent of OSHA Rule 1926.1431(g) and 1926 1501(g) for personnel hoisting.
Hoist hooks incorporate markings forged into the product which address two (2) QUIC-CHECK® features.
• Deformation Indicators -- Two strategically placed marks, one just below the shank or eye and the other on the hook tip, which allows for a QUIC-CHECK® measurement to determine if the throat opening has changed, thus indicating abuse or overload. To check, use a measuring device (i.e. tape measure) to measure the distance between the marks. The marks should align to either an inch or half-inch increment on the measuring device. If the measurement does not meet this criteria, the hook should be inspected further for possible damage.
• Angle Indicators -- Indicates the maximum included angle which is allowed between two (2) sling legs in the hook.These indicators also provide the opportunity to approximate other included angles between two sling legs.
WARNING ! |
• Loads may disengage from hook if proper procedures are
not followed.
• A falling load may cause serious injury or death.
• See OSHA Rule 1926.1431(g)(1)(i)(A) and 1926.1501(g)(4)(iv)(B)
for personnel hoisting by cranes and derricks, and OSHA
Directive CPL 2-1.36 - Interim Inspection Procedures During
Communication Tower Construction Activities. A Crosby
319, 320 or 322 hook with a PL latch attached and secured
with a bolt, nut and cotter pin (or toggle pin) may be used
for lifting personnel. A Crosby 319N, 320N or 322N hook
with an S-4320 latch attached and secured with cotter pin
or bolt, nut and pin; or a PL-N latch attached and secured
with toggle pin may be used for lifting personnel. A hook
with a Crosby SS-4055 latch attached shall NOT be used for
personnel lifting.
• See OSHA Directive CPL 2-1.36 - Crosby does not
recommend the placement of lanyards directly into the
positive locking Crosby hook when hoisting personnel.
Crosby requires that all suspension systems (vertical
lifelines / lanyard) shall be gathered at the positive locked
load hook by use of a master link, or a bolt-type shackle
secured with cotter pin.
• Threads or Split-Nut may corrode and/or strip and drop the load.
• Remove securement nut to inspect or to replace S-322 and
S-3319 bearing washers (2).
• Hook must always support the load. The load must never be
supported by the latch.
• Never apply more force than the hook's assigned Working
Load Limit (WLL) rating.
• Read and understand these instructions before using hook. |
IMPORTANT SAFETY INFORMATION - READ & FOLLOW
• A visual periodic inspection for cracks, nicks, wear, gouges and
deformation as part of a comprehensive documented inspection
program, should be conducted by trained personnel in compliance
with the schedule in ANSI B30.10.
• For hooks used in frequent load cycles or pulsating loads, the hook
and threads should be periodically inspected by Magnetic Particle or
Dye Penetrant. (Note: Some disassembly may be required.)
• Never use a hook whose throat opening has been increased, or
whose tip has been bent more than 10 degrees out of plane from the
hook body, or is in any other way distorted or bent. Note: A latch will not work properly on a hook with a bent or worn tip.
• Never use a hook that is worn beyond the limits shown in Figure 1.
• Remove from service any hook with a crack, nick, or gouge. Hooks
with a nick or gouge shall be repaired by grinding lengthwise,
following the contour of the hook, provided that the reduced
dimension is within the limits shown in Figure 1. Contact Crosby
Engineering to evaluate any crack.
• Remove from service any hook which has threads corroded more
than 20% of the nut engagement length.
• Never repair, alter, rework, or reshape a hook by welding, heating,
burning, or bending.
• Never side load, back load, or tip load a hook.(Side loading, back
loading and tip loading are conditions that damage and reduce the
capacity of the hook). (See Figure 2.)
• Eye hooks, shank hooks and swivel hooks are designed to be used
with wire rope or chain. Efficiency of assembly may be reduced when
used with synthetic material.
• Do not swivel the S-322 or S-3319 swivel hooks while supporting a
load. These hooks are distinguishable by hex nuts and flat washers.
• The S-3322 swivel hook is designed to rotate under load. The S-3322
is distinguishable from the S-322 by use of a round nut designed to
shield bearing.
Company Profile
Baoding Jiazhong Hoisting Machinery Plant. was founded in 1999 in Baoding. Its main development and production facility in Baoding, offers future-oriented solutions with chain systems and components for a wide range of applications.
We specializes in manufacturing standard heavy duty lifting chain (4MM -12MM), including European Standard chain for rigging, electric block chain and also undertake other special standard chain. Each lifting chain we produced was inspected by our experienced technician who had over 30 years research and producing lifting chain experience, and we also use strict quality control testing system to ensure the products' stability and durability.
Jiazhong' s primary purpose is produce heavy duty and more reliable lifting chain for lifting application to achieve superior performance and usage, withstand more abuse, high abrasion resistance, greater lifting load. Each bundle of raw materials come with alloy steel quality inspection report issued by the steelmaker, including the component analysis, production date, produced furnace number, and so on, to ensure the traceability of each batch of raw materials.
As the second largest chain manufacturer, our other hoisting machineries have a huge cost advantage. For hoisting, moving, pulling, driving and conveying, our Jiazhong lifting means, Jiazhong hoist chains, Jiazhong Chain block and Jiazhong Electric hoist are a guarantee of quality, innovation and safety.
In Tradition of Dynamic Innovation "that is in the tradition of a modern and dynamically growing family organization, the Jiazhong Group has officially been nominated as a Hidden Champion of the 21st Century because we are in our defined sectors worldwide leader in quality and technology.
