Selecting the Right Hoist for your Application

Every contractor has two main goals at the start of a new project: to do the job right in a timely manner, and to minimize accidents on the job site by providing workers with superior safety. The chances of a dangerous accident occurring can be greatly reduced, even eliminated, just by choosing the appropriate equipment and following the safety guidelines specified. Too often, safety is sacrificed in the hands of cost. However, it is possible to specify an option that will eliminate safety dangers without breaking the bank.

Choosing the right method
To ensure that the proper hoist is being chosen for the task at hand, the contractor first needs a clear idea of whether the hoist will be transporting materials or personnel. It is imperative that a passenger hoist be used whenever the transportation of people is involved. If both people and material need transporting, contractors must take into account the volume of people that need to be moved versus the volume of materials. If there is a large amount of materials and a considerably smaller group of workers, it may be in the contractor's best interest from both a safety and budgetary standpoint to have two smaller hoists running side by side. Many people are conditioned to believe "bigger is better" when it comes to hoists, and do not always recognize that there are other more cost-effective options available to them.

In addition to determining what the hoist will be carrying, the project's budget and the height and weight requirements should also be considered when choosing a hoist. Some lifting methods like forklifts, cranes, or rope and pulleys may well be the most suitable options for the project. However, these more traditional methods do come with limitations. Forklifts typically have a reach of only 50 to 60 feet, which restricts how high material can be lifted. Cranes can be very expensive (costing up to $1,000 per day) and can not always fit into tight, hard to reach areas. Rope and pulleys run solely on manpower, and can thus slow down productivity over the course of a day.

Chris Ionta, a project manager at NER Construction, faced this problem and chose a platform hoist for a recent granite façade restoration project when cranes, forklifts and pulleys proved to be insufficient and failed to offer the range or stability he needed.

"Safety is always a paramount concern when you're working with materials as heavy as granite slabs," said Ionta. "For this project, I needed a hoist light enough to set up on rooftops with a minimal amount of cribbing, and motorized to provide workers with a stable platform to move around safely upon."

Training
Choosing the proper hoist is imperative, but really only the first step to ensuring worker safety. In order to effectively prevent hoist accidents and promote material handling safety, operators should be fully educated on the proper use of the hoisting equipment on the jobsite. There is no special licensing required to operate a hoist, but most companies will offer certificates upon completion of the training. All hoists come with an operator's manual, and some manufacturers go so far as to offer factory, video, or even on-site training.

When learning how to operate the hoist, the contractor should also take initiative and determine the best place to serve as a staging area for the hoist prior to the installation. Important considerations include figuring out where and how the hoist will be tied into either the scaffolding or the building wall.

Safety considerations
Clearly, all hoists should meet the safety standards set forth by OSHA, as well as address ANSI specifications. In addition to meeting those requirements, most hoists come equipped with standard safety features including limit switches, over-speed brakes, overload sensing devices, and multiple controllers. These features allow the operators to use the hoist correctly and with better control.
