To satisfy different clients requirement, we take full advantages of combining design by connecting to site condition, specified fabricate course, possibly make every step easy and customize.

Low headroom single girder overhead crane has such design concepts as small dimension, light weight, energy-conservation and environment protection. Compared with traditional cranes, the limiting distance is minimum from hook to wall, and headroom is the lowest, which makes cranes work more close to the front, and lifting height higher that increases effective working space of workplace.

Features

1.Light Weight Design

Height: The overall height of the crane can be lower 20%~25% of the tradition crane.

Self weight: The self weight reduced by 20%~30%.

Wheel pressure: The maximum wheel pressure can deduct by 15% ~ 20%.

Size: The small limit dimension can increase the working area.

Structure: With the lightness structure it can cut the construction costs.

2. Modular Design

a). Each spare parts on the crane can be design to series standard modulus , it can lavish the product combination.

b). Its independent modulus is convenient for the transportation.

c). Standard modulus production, it can ensure stability quality of the product, it can shorten the delivery period.

3. Advanced Technology

a). Sandblasting pretreatment for the steel plate, its surface quality can reach to Sa2.5.

b).Using digital cutting machine to cut the web plate, ensure the smooth and precision of the camber curvilinear.

c).Main welding seam adopts auto arc merged welding, Ultrasonic, X ray nondestructive inspection.

d).The bridge and trolley frame adopts floor type boring machine to ensure the flatness of the machine side.

4. High Security

a).The safety supervises system equipped with overload limiter, and on the monitor it can display the loads value, it can remind the operator to prevent the overload.

b).Before the start, the entire controller will start self checking, includes: power voltage, default phase, the effective of each safety protective device and zero position of the button.

5. High Reliability

a).Imported motor, the insulation grade is F, and protective grade is IP54, it shall also have over heated and alarming function, the motor cover adopts aluminum alloy to drawing the molding, with better heat dissipation.

b).Germany imported reducer, harden face gear, improve the bearing ability, better sealing of the shell, ensure there no grease penetration.

c).The main electric elements adopts the international brands include Schneider, Siemens, ABB. The protective grade of the electric control box shall no less than IP 54.

d).The wheel forged by 65 Mn alloy steel, with the performance of abrasive resistance, ant fatigue and long service life.

6. Low-energy and Maintenance-free

a).The total power of crane reduce about 30%, energy conservation and environmental protection.

b).The multi -in-one integrated transmission mechanism has less intermediate ring knot and high transmission efficiency.

c).Adopt frequency control, high and low speed ratio 1:10, work efficiency increased by more than 20%.

d).The “Maintenance-free and easy maintenance “design concept reduces customer maintenance costs.

e).It uses advanced processing technology and high -quality imported components. Its failure rate has been greatly reduced compared to traditional GB crane, helping customers reduce operating costs.

FAQs

1. What makes the smooth‑speed monorail crane “low headroom”?

This Euro‑type crane is specifically designed to reduce the distance between the hook and the runway, achieving 20%–25% lower overall height, which maximizes usable overhead space and allows for higher lift capacity in tight-clearance environments 

2. How does its lightweight and compact structure benefit facility design?

Thanks to a lighter frame (20%–30% lower self weight) and reduced wheel pressure (15%–20%), this crane eases building structure requirements, lowers construction costs, and expands operational workspace through minimized dimension constraints.

3. What design and manufacturing technologies support its precision and quality?

It features modular spare parts for streamlined logistics, sandblasted steel plates (Sa2.5 finish), precision digital cutting, auto arc welding with ultrasonic and X‑ray inspection, and flat, bore-machined trolley frames to ensure structural accuracy and durability.

4. What safety systems are integrated for reliable operation?

Built‑in overload limiters display real‑time load values, preventing overloading. A comprehensive controller self-check process covers power voltage, phase correctness, safety devices, and button zero-positioning to enhance operator safety at startup .

5. Which components improve performance and maintenance efficiency?

It uses imported F‑insulation motors rated IP54 with overheating alarms; German reducers with hardened gears for better load bearing; electrical components by Schneider, Siemens, and ABB (≥IP54); and durable 65 Mn alloy wheels for exceptional abrasion resistance and long service life .

6. How does this crane deliver energy savings and maintenance benefits?

The total power requirement is reduced by about 30%. It employs a multi‑in‑one integrated transmission for high efficiency, supports a wide 1:10 speed ratio via frequency control (boosting work efficiency by over 20%), and offers maintenance-free components to cut long-term operating costs.
