Lifting equipment: how to choose by load capacity

Before choosing lifting equipment, look at the load to be raised and the point where you will fix it: the capacity of the equipment and that of the structure (scaffolding, wall, floor slab) must both exceed it. In our collection the capacities range from 150 to 2,500 kg: jib hoists, tripod hoists and scaffold hoists are used to take site materials up high, magnetic lifters for steel parts, and props to support rather than lift.

Types

• Jib hoist: it has an arm that projects from a fixed support and carries the load out beyond the support, for example from one floor to another. One example is the DM 100E jib hoist Iori Officine.
• Ground and scaffold hoist: used either resting on the ground or fixed to the scaffolding. One example is the DM 100AT.
• Tripod and trestle hoist: a structure on legs that stands on the ground, with no need for a wall to fix it to. Examples are the DM 300 AP Elefantino and the Gruetta GT 350.
• Winch: the drum unit that pulls or lifts the load with a rope. Check the rope, the hook with safety catch, the limit switch and the brake.
• Hydraulic mini crane, lifting table and platform: equipment for handling and raising loads in workshops and warehouses.
• Magnetic lifter: it picks up steel parts with a magnet, without chains or slings.
• Lifting clamps and grips: used to attach the load to the hook. For details on the clamps you can also find the dedicated blog articles.
• Props: they do not lift, they support. They are used to hold a load or a structure in position at height.
• Accessories: bucket holder, extensions, kits such as the Tradelift pack with Stanley extension.

How to choose for the job

Key features to check

• Capacity (kg): this is the maximum load. In the collection it ranges from 150 to 2,500 kg, with intermediate values such as 285, 300, 670, 800, 1,000 and 2,000. Also take into account the weight of slings and containers, not just of the material.
• Equipment weight (kg): from a few kg for accessories and clamps to 64-90 kg for hoists. If you have to assemble it by hand on site, the weight matters.
• Power (kW), frequency (50 Hz) and rpm: these are motor data for electric hoists. In the collection the power ranges from 0.75 to 6 kW. Check that the site power supply is compatible.
• Dimensions (width, length, height): you need them to know whether it will go through the door, whether it fits in the van and how much space it takes up.
• Outreach: on the data sheets of some models the arm distance is shown. The more outreach, the further from the support you can take the load.

Common mistakes

• Checking only the capacity of the equipment. The structure you fix it to (scaffolding, wall, floor slab) must also be able to bear the load.
• Standing under the suspended load. No one must pass or stop under a raised load.
• Lifting with a jerk. The load is lifted slowly.
• Attaching with unsuitable accessories. Chains, slings and hooks each have their own capacity and their own safety catch: use those suited to the load.
• Skipping the checks. Before use, check the rope, hook, limit switch and brake; the periodic inspections required are carried out on time.

Frequently asked questions

What is the difference between a hoist and a winch?

The hoist is a complete structure with motor, rope and support, designed to lift material. The winch is only the pulling unit: it requires a suitable fixing point.

When is a magnetic lifter enough?

When you have to move steel parts with a flat, clean surface. It does not work on non-magnetic materials.

Can I use a scaffold hoist for people?

No, unless the manufacturer's data sheet expressly allows it. These hoists are designed for materials: if in doubt, ask the AMES technicians.

Are periodic inspections required?

Yes, lifting equipment is subject to periodic inspections. The intervals depend on the equipment and on the regulations: ask the AMES technicians.

To choose the right capacity, see the Lifting collection, or ask for a quote or advice from the AMES technicians, stating the load, the height and the fixing point.
