When not in use, the ramp folds compactly and is latched in an upright position at the rear of the vehicle. The ramp may be unfolded and extended in order to transport goods to and from the vehicle. As used, the ramp also may be latched in a half-ramp arrangement to serve as a bridge or dock plate. In the half-ramp arrangement, the ramp is folded to form two legs of a three-dimensional triangular structure, so that one portion of the ramp supports the other and allows it to bear weight. When you have a health condition that requires use of a wheelchair, you quickly find which establishments have ADA compliance and which do not. When you get in or out of your home, car, or van a portable wheelchair ramp is a handy thing to have around. Here is what you need to consider when purchasing a portable wheelchair ramp.  Ramps according to the present invention are lightweight, sturdy, and... Tue, 16 Mar 2010 09:56:30 +0100 http://www.blogigo.com/zhongxinladder/Aluminum-Ramp-attached-and-used-for-the-loading/32/ http://www.blogigo.com/zhongxinladder/Aluminum-Ramp-attached-and-used-for-the-loading/32/ The current invention relates to the field of household  step ladders , and to the design of step ladders to permit a folding structure to be used as a self-supporting, or free-standing ladder, while maintaining an adequate degree of stability to prevent over-tipping and dangerous falls. Step ladders provided a means for an individual to climb to a height for manipulating objects or performing work where the ladder is essentially free-standing; that is, the ladder depends solely upon its construction and erection to insure its stability, in comparison to standard extension ladders which are braced against a structure to be climbed. A typical step ladder is designed to be folded into a convenient size for storage and carrying, and the requirement that it be portable is a further constraint, restricting the total weight of the ladder. Thus, a typical step ladder will be found to weigh thirty pounds or less weight, in order to insure that it may be easily handled, and it is typically designed to... Tue, 16 Mar 2010 09:36:00 +0100 http://www.blogigo.com/zhongxinladder/Step-ladders-provided-means-for-individual-climb/31/ http://www.blogigo.com/zhongxinladder/Step-ladders-provided-means-for-individual-climb/31/ The invention relates to an Aluminum step ladder with ladder legs and a ladder top or platform, foldably connected to the ladder legs and arranged to receive certain tools. The step ladder can be opened into an A-frame state in which it is free standing. The ladder top is molded from a hardenable flowable material such as a curable polymer forming a rigid shape. The ladder top generally comprises an inverted cup shape having a flat central web serving as the platform for placing articles such as tools, paint brushes, containers of paint and so on. The web has a periphery formed with mined-down flanges and an underside formed with ribs that extend between and interconnect the flanges, wherein the flanges and ribs coact to stiffen and/or strengthen the ladder top. The top side of the web has a pair of protruding eye-loops that are spaced and arranged for removably receiving a pair of hooks on a roller pan such that the pan can be cantilevered over the edge of the platform, away from the step side of...

Make sure the feet of the ladder can’t slip backward. On soft ground, flip up the ladder shoes so the spurs poke into the ground. On decks, screw down a cleat. Make sure the top of the ladder is resting on a flat surface and doesn’t slide or wobble when you put weight against When climbing the ladder grab onto the rungs of the Household ladder using a hand over hand method never letting go of one rung before before grabbing the next. Sliding your hands up the beam (side) of a ladder is unsafe because you may not have as secure a grasp as you would when using the rungs to climb with. Ladders are known to be unstable and often require the assistance of a second person for steadying the ladder when a first person has climbed the ladder. However, another person is not always available when a ladder has to be used. There have been many devices made for Ladder stabilizer , and yet they do...

When not in use, the ladder stabilizer closes flush against the back of the ladder steps. An alternate embodiment includes a ladder stabilizer for an extension ladder comprising an extending leg and a stabilizer arm with the top of the extending leg attaching to a slide lock that slides along a channel mounted on the side of the ladder. Bolts passing through expansion inserts hold the channel onto each side of the ladder. A folding ladder can be a handy tool to have around the home. When unfolded, a Aluminum step ladder makes it possible to access hard to reach places. When folded, it can be easily stored away and kept out of site. There are several things you should consider when purchasing a folding ladder. Setting up an extension ladder at the correct angle is the key to working safely on the... Tue, 02 Mar 2010 10:26:52 +0100 http://www.blogigo.com/zhongxinladder/What-claimed-new-and-desired-secured-Letters-Patent/27/ http://www.blogigo.com/zhongxinladder/What-claimed-new-and-desired-secured-Letters-Patent/27/ For safety, a rigid ladder should be leaned at an angle of about fifteen degrees to the vertical. In other words, the distance from the foot of the ladder to the wall should be about one quarter of the height of the top of the ladder. At steeper angles, the ladder is at risk of toppling backwards when the climber leans away from it. At shallower angles, the ladder may lose its grip on the ground. Ladder stabilizers are available that increase the ladder's grip on the ground. A ladder standoff, or stay, is a device fitted to the top of a ladder to hold it away from the wall. This enables the ladder to clear overhanging obstacles, such as the eaves of a roof, and increases the safe working height for a given length of ladder.     * Rope ladders are used where storage space is extremely limited, weight must be kept to a minimum, or in instances where the object to be climbed is too curved to use a rigid ladder. They may have rigid or flexible rungs. Climbing a rope ladder requires more...

In most cases now it is simply said to be ‘unlucky’, but in previous times to walk under a ladder might result in you never marrying, or dying on the gallows. The first known reference to this belief is little more than 200 years old, in Grose's Provincial Glossary (1787:63). For those unfortunate enough to have walked under a ladder, a number of traditional remedies are prescribed—spit through the ladder, spit over your left shoulder, or keep your fingers crossed till you see a dog, do not speak till you see a four-legged animal, make the sign of the cross, and so on. There have also been a number of attempts to explain the belief: the Devil lurked under the ladder at the Crucifixion, the ladder/wall/floor make a triangle which is symbolical of the Trinity, and the...

Since it’s gutter cleaning season, I’ll focus on the tall extension ladders. Select the right Household ladder Ladders have a duty rating from the American National Standards Institute.  This rating includes the maximum weight it’s designed to handle, which includes the user, material and tools. Type III: light duty - up to 200 lbs Type II: medium Duty - up to 225 lbs Type I: Heavy Duty - up to 250 lbs Type I-A: Extra Heavy Duty - up to 300 lbs* Type I-AA: Special Duty - up to 375 lbs* * If you and your load are getting close to or above 300 lbs, consider renting a lift. Inspect Before Each Use     * Check all bolts and rivets     * Be sure the rungs are clean ...

Because the most important thing to notice, is that there are different levels of participation, ranging from full participation to fake participation, from being in-control to being under control. After this one, other ladders of participation have been described: for example the Ladder of Children’s Participation (also called the Ladder of Youth Participation), from (1997) Roger Hart, Children’s Participation: The Theory And Practice Of Involving Young Citizens In Community Development And Environmental Care MOBILE AND SAFETY STAIRS – Mobile Stairs for access to mezzanine floors or for use in warehouse applications. There are flexible top platform configurations to allow exit ‘to front’ or ‘to side’ off the top platform. WAREHOUSE STEPS – Also known as Ladder stabilizers or rolling ladders they have a large stable platform at the top from which to work. These ladders are fitted with wheels to allow them to be moved easily and the wheels...

Handrails must not be more than 37 inches (94 cm) high nor less than 30 inches (76 cm) from the upper surface of the handrail to the surface of the tread.  Handrails must provide an adequate handhold for employees to grasp to prevent falls.  Temporary handrails must have a minimum clearance of 3 inches (8 cm) between the handrail and walls, stair rail systems and other objects.  Stairways with four or more risers, or that rise more than 30 inches (76 cm) in height— whichever is less—must have at least one handrail.  Winding or spiral stairways must have a handrail to prevent use of areas where the tread width is less than 6 inches (15 cm). Midrails Midrails, screens, mesh,...

Specifically, there are rules for stairs used during construction and stairs used temporarily during construction, as well as rules governing stair rails and handrails. Stairways Used During Construction The following requirements apply to all stairways used during construction:  Stairways that will not be a permanent part of the building under construction must have landings at least 30 inches deep and 22 inches wide (76 x 56 cm) at every 12 feet (3.7 m) or less of vertical rise. Stairways must be installed at least 30 degrees —and no more than 50 degrees—from the horizontal.  Variations in riser height or stair tread depth must not exceed 1/4 inch in any stairway system, including any foundation structure used as one or more treads of the Aluminum step ladder .  Doors and gates opening directly onto a stairway must have a platform that extends at least 20 inches (51 cm) beyond the...

Use wooden ladders built at the jobsite with spliced side rails at an angle where the horizontal distance is one eighth of the working length of the ladder. In addition, the top of a non-self-supporting ladder must be placed with two rails supported equally unless it is equipped with a single support attachment. Aluminum step ladder  Do not use the top or top step of a stepladder as a step.  Do not use cross bracing on the rear section of stepladders for climbing unless the ladders are designed and provided with steps for climbing on both front and rear sections.  Metal spreader or locking devices must be provided on step ladders to hold the front and back sections in an open position when ladders are being used. Portable Ladders The minimum clear distance between side rails for...

(Suited for painting and similar tasks.)     * Type III – Household Ladder : light-duty with a load capacity of 200 pounds.             There are many types of ladders available on the market. If it is intended to be portable and used by a single person, it should fit into one of the three basic categories. It is rare that you just go up and down a ladder.  You use it to do a job, so you could be carrying tools and materials up it.  You could be on it and be sawing or drilling.  You can apply many kilograms of thrust to the ladder, over and above your own weight when you are working on it, so you need a solid support. As far as I know ladder rungs...

There are two types: rigid ladders that can be leaned against a vertical surface such as a wall, and rope ladders that are hung from the top. The vertical members of a rigid ladder are called stringers (US) or stiles (UK). Rigid ladders are usually portable, but some types are permanently fixed to buildings. Rigid ladders are available in many forms, such as: Step ladder:one kind is hinged in the middle to form an inverted V, with stays to keep the two halves at a fixed angle,which is called double sided step ladder. And the other kind is the  vertical ladder, also called straight ladder. Another is household ladder ,it is like double sided step ladder.These Aluminum step ladder are the popular products of Zhongxin.
