Product catalog summary

Specifications Overview
The Cat® 7495 HD Electric Rope Shovel is designed for heavy-duty mining operations. It features a dipper payload capacity of 81.8 tonnes (90 tons) and a dipper capacity ranging from 19.1 to 61.2 m³ (25-80 yd³). The boom length is 20.4 m (67 ft), and the dipper handle's effective length is 10.9 m (35 ft 10 in).

Weights
The working weight with dipper and standard links is 1,306,346 kg (2,880,000 lbs), while the net weight without ballast or dipper is 972,502 kg (2,144,000 lbs). The general-purpose dipper weighs 73,482 kg (162,000 lbs), and customer-furnished ballast is 260,362 kg (574,000 lbs).

Main Structures
The crawler mounting has an overall width of 9.98 m (32 ft 9 in) with standard treads and 10.44 m (34 ft 3 in) with wider treads. The revolving frame is constructed from welded, impact-resistant steel, measuring 8.38 m (27 ft 6 in) in length and 4.29 m (14 ft 1 in) in width.

Operational Ranges
The shovel's optimal working ranges include a dumping height of 10.6 m (34 ft 10 in) and a maximum cutting height of 17.3 m (56 ft 10 in). The maximum dumping radius is 21.0 m (69 ft), and the cutting radius is 23.97 m (78 ft 8 in).

Electrical Systems
The shovel uses an IGBT Acutrol drive system with power requirements of 3 phase, 50/60 Hz, 7200 V. The average 15-minute demand ranges from 832 to 1,165 kW, with a peak power of 3,330 kW. The system voltage is nominally 7200 V.

Front End Components
The boom is made from welded, impact-resistant steel with twin-grooved, flame-hardened sheaves. The boom point sheave diameter is 2.43 m (8 ft), and the handle diameter is 86.36 cm (34 in).

Rope Data
The hoist uses two ropes with a diameter of 69.8 mm (2.75 in), while the crowd and retract ropes are 63.5 mm (2.5 in) in diameter. The boom suspension uses four ropes, each 82.6 mm (3.25 in) in diameter.
