Bobob LIFT 25-ton Truck-mounted Crane Lifting Test Complete Record: Strength Witness, Heavy Load Worry-Free!

I. Test Background: Why does a 25-ton truck-mounted crane need extreme testing?

In the field of construction machinery, "parameters do not equal true performance"! BOB-LIFT conducted a full-condition pressure test on a 25-ton truck-mounted crane to verify three core issues:

Is the nominal lifting capacity of 25 tons true?

2. Can the stability under a long arm span ensure safety?

3. Will the hydraulic system deteriorate after continuous operation?

Ii. Full Test Documentation: Data Never Lies

Static load testing

Challenge: Hoisting a 25-ton counterweight block with a maximum working radius of 18 meters

Result:

The counterweight blocks lift off the ground smoothly without any visible structural deformation

The torque limiter gives real-time alarms and automatically cuts off power when overloaded by 0%

2. Dynamic stability test

Challenge: 360° continuous rotation + Simulation of 7-level wind load (wind speed 13.9m/s)

Result:

The rotary accuracy error is less than 1cm

The anti-sway system keeps the swing amplitude of the lifted object within 5°

3. Durability Marathon

Challenge: 72-hour continuous cycle operation (hoisting - translation - unloading)

Result:

The hydraulic oil temperature is always kept below 65℃ (critical value: 90℃).

The wear of key parts (steel wire rope, pin shaft) is only 60% of the industry average

Iii. Technical Analysis: Where Does Hard Power Come From?

1.Strengthen structural design

It adopts BS700MC high-strength steel, and the thickness of key pressure-bearing parts is increased by 20%

Finite element analysis (FEA) optimizes the stress distribution and eliminates weak points

2. Intelligent hydraulic system

The Rexroth proportional valve from Germany and the dual-pump combined flow technology increase the flow rate by 30%

It features a unique "thermal balance loop" design to prevent performance degradation at high temperatures

3. Safety redundancy configuration

Triple protection: torque limiter + Angle sensor + emergency manual pressure relief

Optional AI anti-sway system (real-time correction of the lifted object trajectory through the camera)

Iv. Purchasing Suggestions: Is your working condition suitable for the 25-ton class?

Recommended scenarios:

Steel structure factory building hoisting (H-shaped steel ≤22 tons)

Port standard containers (20/40-foot containers)

Wind power equipment maintenance (nacelle components ≤25 tons)

Unrecommended scenarios:

Super-radius hoisting (larger models should be selected for hoisting over 18 meters)

Extreme low temperature (< -30℃, customized hydraulic oil formula required)

Every second we test is for the safety and efficiency of every minute on your construction site.
