How to Select a Tilting Spreader?

Below is a practical, readily applicable method for selecting a tilting spreader, following the sequence of "First determine the working conditions → Then select the type → Then calculate parameters → Finally verify safety." This method is suitable for factories, hoisting operations, equipment installation, and other similar scenarios.

I. First, clarify 5 core selection criteria (must be determined first):

Type of object to be lifted:
Steel plates / steel profiles / steel structural components
Precast concrete components (wall panels, beams, slabs)
Glass, stone
Large equipment / enclosures. Different materials, surfaces, and weights determine the type of spreader.

Weight of the object to be lifted (maximum rated lifting capacity):
Must be calculated based on the maximum single-piece weight plus a safety margin, generally 1.1 to 1.25 times.

Tilting method:
90° tilt
180° tilt
Any angle tilt
Different tilting angles correspond to different spreader structures.

Surface condition of the object being lifted:
Smooth surface (steel plate, glass)
Rough/Coated/Easily damaged surface
With holes, lugs, or lifting points
Determines whether protective pads, special clamps, or special lifting beams are needed.

Site Conditions
Is space limited?
Does it need to be matched with a crane/overhead gantry?
Does it need quick switching of lifting equipment?
II. Selecting Lifting Equipment Category by Type of Object (Most Critical)
1) Steel Plate/Sectional Steel/Steel Structure Tilting
Common Types:
Tilting Beam (Horizontal Beam Type)
Suitable for: Long strips, plates, box-shaped structures
Advantages: High versatility, stable stress
Dedicated Tilting Clamp (Mechanical/Hydraulic)
Suitable for: Steel plates, section steel, precast components
Advantages: High clamping force, automatic locking, high safety
Tilting Lifting Equipment Combination (Beam + Clamp)
Suitable for: Large, irregular components
Selection Points:
Steel plate thickness, width, length
Whether coated, whether susceptible to indentation
Whether anti-fall and anti-slip structures are required
2) Concrete Precast Component (Wall Panel, Beam, Slab) Tilting
Common Types:
Dedicated Concrete Tilting Lifting Equipment
With soft straps/slings + clamps, protecting the corners of components
Four points/ Six-point tilting hoist
Suitable for large wall panels and precast beams
Selection points:
Component size and weight
Whether lifting point positions are reserved
Whether crack prevention and edge/corner damage prevention are required
3) Glass/Stone tilting
Common types:
Vacuum suction cup hoist
Suitable for flat, non-porous, and uncoated glass
Dedicated glass tilting frame/lifting beam
Suitable for large-size, heavy glass
Selection points:
Glass size and thickness
Whether the surface is coated and susceptible to scratches
Vacuum system reliability and backup pump
4) Large equipment/box tilting
Common types:
Dedicated tilting lifting beam
Customized according to equipment center of gravity and lifting lug position
Combined hoisting equipment (wire rope + balance beam + dedicated clamp)
Selection points:
Center of gravity position
Whether the equipment is susceptible to impact or deformation
Whether multi-point balancing is required
III. Selection by tilting method
90° tilting: Ordinary tilting lifting beam/clamp is sufficient
180° tilting: Preferably use tilting clamps with self-locking or dedicated tilting frame
Any angle tilting: Must use hydraulic/ Mechanically self-locking tilting lifting devices must not be tilted directly with ordinary wire ropes.

IV. Mechanical Calculations and Safety Factors (Required)

Rated Lifting Capacity QQ = Maximum Weight of Lifted Object × 1.1～1.25 (Safety Margin)

Safety Factor
General Structure: ≥ 5
Important Equipment/Personnel Coordination Lifting: ≥ 6～8
Hydraulic/Mechanical Locking Mechanism: ≥ 4
The tilting torque must ensure that the lifting device will not tilt itself or loosen during the tilting process.

V. Final Selection Steps (Can be followed directly)

Determine the object to be lifted: weight, dimensions, material, surface, lifting points

Determine the tilting angle and method

Select the main type of lifting equipment (tilting beam / clamp / vacuum suction cup / special frame)

Calculate the rated load and safety factor

Confirm the need for: anti-indentation, anti-fall-off, self-locking, hydraulic, quick-change

Check manufacturer's samples or customized solutions

Acceptance: No-load test → Static load test → Dynamic load test

VI. Common Selection Mistakes (To be avoided)

Selecting only based on weight, without considering the center of gravity and tilting torque

Using ordinary steel wire rope for direct tilting (extremely easy to fall off, dangerous)

Ignoring surface protection, leading to indentations and scratches

Insufficient safety factor

Selecting large lifting equipment despite insufficient site space
