Lift-It® Manufacturing offers the largest range of standard products available to satisfy many different lifting applications. In addition to our standard line is the ability to create a custom designed solution to meet your lifting challenges.
We are proud to distribute products designed and manufactured by The Caldwell Group. They have been manufacturing engineered Material Handling Equipment for over 55 years. The goal is to design and manufacture high quality, long lasting lifting products that will safely increase productivity and reduce operating cost.
BENEFITS OF MATERIAL HANDLING EQUIPMENT
- Increased productivity.
- Increased safety from an engineered product that is compliant to applicable regulations and standards.
- Durability for long lasting service.
- Registered metal tags with unique serial numbers for traceability.
- Rated capacities and safety warnings.
The American Society of Mechanical Engineers (ASME) has developed standards that apply specifically to the Material Handling Equipment we supply. ASME B30.20 provides detailed information on the classifications, marking, construction, installation, inspection, testing, maintenance and operation of Below the Hook (BTH) Lifting Devices.
ASME BTH-1 provides detailed information on the design criteria of Below the Hook Lifting Devices.
ASME B30.9 provides detailed information on the fabrication, markings, usage, inspection and maintenance of lifting slings. These standards serve as a guide to government authorities, manufacturers, purchasers and users of lifting devices.
PROOF TESTING AND CERTIFICATION
Please specify if new material handling devices are to be proof tested and certified. There is a nominal charge for this service.
Experienced engineers and technicians provide first-class service to keep your equipment running at peak performance. From training and maintenance, consultations to inspections, modernizations and repairs, we are committed to helping you prolong the life of your lifting equipment and accessories. We will save you time and money, improve safety and productivity and reduce downtime. Our team utilizes the latest technologies and adheres to all American Society of Mechanical Engineers (ASME) standards, keeping you and your equipment safe.
TRAINING & MAINTENANCE CONSULTATIONS
A Service Team member works with your operators to ensure proper use of equipment and can create a customized maintenance plan around key considerations and trouble spots to keep your equipment running at peak performance.
Our custom maintenance programs minimize costly downtime, increase safety and dramatically extend the life of your lifting equipment, protecting your investment. Maintenance is extremely important because identifying small repair issues early can prevent major damage and failure later in the life of your equipment.
Once the Service Team has completed an inspection, we will provide a complete report describing the extent of damages and repairs required, including a firm quote, for your review before any repairs are made to the equipment. An experienced technician can be sent to your location to inspect equipment through operational tests and visual examination. Minor repairs, once identified and approved, often can be performed on-site to help minimize downtime.
Once major repairs are complete, the equipment is tested; repainted and new capacity and safety labels are applied. Our commitment to quality and service holds true for our repairs, as each piece of equipment repaired by our team carries with it the same new product warranty that accompanies all of our products.
Our team uses the latest design technologies to determine if your equipment can be: upgraded, modified or refurbished to help you tackle bigger loads, severe duty cycles, extreme weather, correct recurring issues and improve performance. After modernization, equipment is tested, repainted, labeled and covered by the same new product warranty that accompanies all of our products.
|KEY ASME STANDARDS
DESIGN OF BELOW-THE-HOOK LIFTING DEVICES (BTH-1)
ASME BTH-1 designates design criteria for Below-the-Hook Lifting Devices (ASME B30.20) and serves as a guide to designers, manufacturers, purchasers and users of these types of Material Handling Devices.
All Below-the-Hook Lifting Devices shall be designed for specific rated loads and load stresses as they affect the components of the lifting device.
A design category and service class shall be designated and marked on lifters and all quotations, drawings and other documents relating to the Material Handling Device.
Design Category B should be designated when conditions of the lift are not always defined or predictable or when load conditions could be severe. Design factors for Design Category B Lifting Devices shall not be less than 3 for limit states of yielding or buckling.
Service class is the specified fatigue life of the lifter.
- Service Class 0: 0 to 20,000 load cycles
- Service Class 1: 20,001 to 100,000 load cycles
- Service Class 2: 100,001 to 500,000 load cycles
- Service Class 3: 500,001 to 2,000,000 load cycles
- Service Class 4: Over 2,000,000 load cycles
STRUCTURAL AND MECHANICAL LIFTING DEVICES (B30.20)
Structural and mechanical lifting devices shall be designed according to ASME BTH-1, Design Category B, taking into consideration the load, including the weight of the Lifting Device. The design service class is determined by the expected fatigue life of a lifter based on the number of load cycles.
- All welding shall comply with ANSI/AWS D14.1 and ASME BTH-1.
- Guards should be provided for exposed moving parts.
- Electrical equipment and wiring shall comply with ANSI/NFPA 70 and ASME BTH-1.
- Contact us for information on modifications or repairs to maintain compliance with ASME standards.
- The rated capacity shall be marked on the Lifting Device.
- Lifting Devices shall be marked with the following information:
Manufacturer’s name and address
Lifter weight, if over 100 lbs. (45 kg)
Cold current (amps), when applicable
Rated voltage (when applicable)
ASME BTH-1 Design Category
ASME BTH-1 Service Class
- Product Safety Labels.
When possible, all Lifting Devices shall have labels that include the appropriate signal word, according to ANSI Z535.4
including the proper cautionary notice to operators warning against improper use. When it is not possible to include the
above, a label shall be affixed, referring users to the manufacturer’s instruction manual for product safety information.
Before use, a new, altered, modified or repaired Lifting Device should be load tested and inspected. Contact the manufacturer for information regarding the appropriate test load for the Lifting Device.
Please Note: Definitions: Should = a recommended procedure. Shall = a required procedure.
|CARE AND USE
Material Handling Devices purchased from Lift-It® Manufacturing have been designed for specific tasks and to withstand particular forces imposed. Product specific information will be sent with each product. Guidelines for installation, inspection, maintenance and repair, safe operation and operator training follows:
Lifting equipment shall be assembled and installed in accordance with the manufacturer’s instructions, unless other specific arrangements have been approved in writing by manufacturer. When lifter/auxiliary power supply is required, user inspection shall ensure that the power source complies with ANSI/NFPA 70, National Electrical Code and shall include a power disconnect switch as required by ANSI/NFPA 70, based on the equipment requirements. If electrical connections are made, the power supply and corresponding power disconnects shall be connected to the line side (power supply side) of the crane disconnect or to an independent circuit as specified in the manufacturer’s operating instructions.
Check for correct rotation of all pumps and power units, lubrication of moving parts and filling of reservoirs, all in accordance with manufacturer’s instructions.
