Whenever you lift, make sure you do the job right, from your initial inspection to the end of the lifting operation. PPE Requirements Before you start, you should use all the Personal Protective Equipment (PPE) normally required for a work area, including eye and hand protection, and a hard hat. Any timea load is lifted above 5 feet or shoulder height, there is a greater risk of head injury. Wearing a hard hat will minimize the risk. Pre-Operational Checks Users should follow pre-operation inspection and preparation procedures to identify potential problems, reduce the chances of accidents, and enhance the safety of their work environment. OSHA 1910.179(j)(2) defines the activities performed for frequent inspections (daily). The five components of this inspection are: All function operating mechanisms for maladjustment or excessive wear Air or hydraulic systems for deterioration or leakage Hooks for deformation or cracks Hoist chains for excessive wear, twisting, distorted or stretched links Rope reeving for noncompliance with manufacturers recommendations Columbus McKinnons training department presents a walk-through of a proper pre-operation check of a hoist on their YouTube Channel: http://www.youtube.com/watch?v=HD-n4_fRtlk&feature=digest_fri . Two prime causes of accidents are overloading and poor rigging. To prevent accidents, we suggest these guidelines: Know the hoist lifting capacity Always know the weight of the object you are lifting Never exceed the working load limit Train operators on proper rigging techniques as well as hoist operation Have rigging handbooks and proper equipment available for use. Lever tools and manual hoists or chain falls are designed to lift under the power of one person.

Stationary steam engines were commonly used to power mine hoists through the 19th century and into the 20th, as at the quince Mine, where a 4-cylinder cross-compound corliss engine was used. 6 Modern hoists are powered using electric motors, historically with direct current drives utilizing solid-state converters and find your career.

Katydids are "the potato chips of the rain forest," scientists say. Christian Ziegler/ Minden Pictures / Getty Images Panama's katydids come in all sizes. The big one on the left is a Steirodon careovirgulatum. The little one is likely a new species for Panama. Biologist Sharon Martinson has tentatively named it Pycnopalpa sincordata.

But scientists are discovering that some forest dwellers also communicate in ways humans usually can't hear via ultrasound. A team from Dartmouth College has recorded these signals in treetops on a pristine Panamanian island called Barro Colorado , and slowed them down to make sense of them. The ultrasonic chatter, it turns out, is actually a complicated conversation between mating insects and the bats that aim to eat them.
