hengjian Fanrong Machinery Parts Co., Ltd., as a professional Manufacturer and Exporter of Sightseeing Elevator Counterweights, delivers precision-engineered cast iron balancing systems tailored for glass-walled elevators in high-traffic commercial and tourist environments.
Our overseas journey began in March 2018 when we welcomed our first international client from Spain. After multiple rounds of technical communication regarding their specific load curve requirements, we customized a counterweight solution that reduced their elevator's motor power loss by 18%—a figure validated by their 12-month operational data.
Glass-walled elevators amplify operational vibrations and metallic sounds—often traced to loose pressure plate bolts or layered shift. Our design incorporates our Utility Model Patent for Forklift Counterweight Inspection Tool principles, applying similar precision alignment to elevator counterweights. Each Sightseeing Elevator Counterweight is dynamically balanced before shipment to ensure <0.5mm runout, minimizing wire rope and sheave wear.
Sightseeing elevator shafts often prioritize transparency over spacious machine rooms. Our modular block system (individual unit weight: 5–50kg), protected by our Adjustable Counterweight Block for Forklifts patent, supports on-site layered stacking and quantity adjustment without custom tooling. Installation time: 0.5–1 hour per unit.

We provide free design consultation within 1–3 working days. Send us your shaft drawings and load parameters—we calculate the ideal weight distribution and block layout. OEM customization is fully accepted, including:
· Shape modifications to fit panoramic elevator curves
· Specific hole patterns matching your OEM rail system
· Weight segmentation for manual handling (max 25kg per block option)
Our Sightseeing Elevator Counterweights have been installed in over 200 projects across Southeast Asia, Europe, and North America. They consistently withstand:
· Temperature extremes from -20°C to +60°C (installation unaffected by weather)
· Humidity up to 95% (anti-corrosion coating passes 120-hour salt spray)
· Repeated impact loads equivalent to 1.5x rated capacity
Our intellectual property portfolio includes:
· 1 National Invention Patent (casting density optimization process)
· 8 Utility Model Patents covering practical innovations such as:
o Forklift counterweight inspection tool
o Conveniently adjustable forklift counterweight device
o Electric forklift counterweight
o Adjustable counterweight block for forklifts
Every shipment includes material test certificates, dimensional reports, and balance verification records.
We package each Sightseeing Elevator Counterweight with:
· Pallet or wooden case (option to add waterproof film)
· Secured strapping and shock-absorbing foam
· Container loading photos and weight distribution report for safe transport
MOQ is 1 full container, and we coordinate with freight forwarders experienced in cast iron cargo to minimize shipping damage.
Glass elevators in atriums, lobbies, and restaurant floors benefit from our quiet operation and aesthetic adaptability. Our counterweights are painted to match interior color schemes upon request.
High-traffic scenic elevators (e.g., mountain cable car stations, tower observatories) require robust anti-overturning properties. Our high-density cast iron lowers the equipment's center of gravity, improving seismic stability by 25% compared to standard designs.
Airports, metro stations, and cruise terminals use sightseeing elevators for passenger flow. Our modular structure allows quick on-site adjustment if load parameters change during refurbishment—no need to replace entire assemblies.
We also supply counterweights for:
· Stage and performance lifts (where silent operation is critical)
· Hospital panoramic elevators (where smooth acceleration protects sensitive medical equipment)
· Residential panoramic units (where space is severely limited)
Q: What problems often occur with sightseeing elevator counterweights, and how do you address them?
A: Two main issues based on field feedback: (1) Counterweight shift—regular vibration or metal collision sounds during operation, mainly due to loosening of pressure plate bolts. Our pre-torqued bolts with locking washers solve this. (2) Improper installation—if not fixed in layers or stacked illegally on the car top, the balance coefficient changes, increasing squatting risks. We provide clear layering instructions and color-coded block labels to prevent this.
Q: Can I get a sample before placing a bulk order?
A: Yes, samples are available. Sample costs and shipping are borne by the buyer; we deduct the sample fee from your first full container order.
Q: How long does delivery take?
A: Two scenarios— • You provide the mold: 25–30 days. • You need us to develop the mold: 25 days for mold making + 25 days for production = 50 days total.
Q: Do you have stock for urgent projects?
A: We maintain a safety stock of standard sizes (500kg, 800kg, 1,000kg) for quick dispatch. Contact our sales team to check current availability.
Q: What certifications do your products hold?
A: Our factory strictly implements ISO 9001, ISO 14001, and ISO 45001. We also hold national High-Tech Enterprise certification and utility model patent certificates. International certifications (CE, etc.) are available upon request and are applied per shipment.
With our headquarters in the Beijing-Tianjin-Tangshan industrial belt, we source raw materials from state-certified foundries and maintain a dedicated QC team of 24 inspectors. Our 209 employees—including 18 R&D engineers—continuously refine our casting process, achieving a 97%+ first-pass yield rate. Sightseeing Elevator Counterweights now operate in Japan, South Korea, Germany, and the United States.
Supply chain reliability: With two independent electric furnaces and a 15,000-ton annual raw material inventory capacity, we maintain production continuity even during peak seasons.
We provide balancing solutions backed by verifiable data, patents, and a 12-month warranty against manufacturing defects. Every unit carries our brand promise: "Standardization for safety, management for efficiency, quality for growth, and credibility for survival."
