Side-hung Electric Hoist Trolley: the "smart heart" of the single-girder bridge crane
Classification:
Product Introduction
The side-mounted electric hoist trolley is the core functional module of the single-girder crane. Through structural innovation, it breaks through the low clearance limitation and adapts to the efficient lifting needs of workshops, warehouses and other scenarios.

Technical Parameters:
| Lifting Capacity | 0.5~20 tons (customizable up to 25 tons) |
| Traverse Speed | 0~20 m/min (frequency control with stepless speed adjustment) |
| Work Duty | A 3-A 6 |
| Braking response time | ≤0.2 s (instant braking at power failure) |
| Trolley Weight | 0.3~3.5 tons (corresponding to 0.5~20 tons lifting capacity) |
Selection and Application: Precisely Adaptable to Four Scenarios
1. Core Selection Logic
Clearance Priority: Measure the clearance under the beam (e.g., if the clearance is 3 m, select a model with a lifting height ≥ 2.5 m);
Frequency-Driven: For Class A 3, choose the Economy model (gear quenching and tempering); for Class A 5, choose the Reinforced model (gear quenching);
Environmental Adaptability: For humid environments, choose IP 54 protection; for chemical applications, choose a flameproof motor + junction box.
2. Typical Applications
Low-headroom factories: Machine shops (equipment lifting), warehouses (shelf stacking), and light industrial (material handling). Floor heights ≤ 6 m are preferred.
Gantry Extensions: Side-hung gantry cranes (with L-shaped outriggers for increased span capacity) are used for bulk material loading and unloading in freight yards.
Special Modifications: Grab-type (bulk materials), explosion-proof (chemical), and wireless remote control (height work).
