4′ x 14′ ESC ASF4 Steel-Framed Aluminum Trench Box

Description

The ESC ASF4 4′ x 14′ steel-framed aluminum trench box combines a steel frame with aluminum panels to provide a durable trench box for utility, construction, and excavation work. Its 4-foot height and 14-foot length provide an extended protected work area for underground utility projects where additional working length is beneficial.

The ASF4 4×14 has a 751 PSF panel capacity and weighs approximately 4,080 lbs. It provides 24 inches of pipe clearance and 148 inches (12′4″) of length between the spreaders.

Manufacturer data provides maximum depth ratings of 19 feet in B-45 soil, 15 feet in C-60 soil, and 11 feet in C-80 soil, subject to the manufacturer’s tabulated data, proper shield configuration, and evaluation by the project’s competent person.

4′ x 14′ ESC ASF4 Price and Spreader Configuration

The 4′ x 14′ ESC ASF4 Steel-Framed Aluminum Trench Box is priced at $12,875 and comes standard with four 36″ spreaders. This configuration provides a complete trench shield setup ready for assembly and use.

Other spreader sizes are available to accommodate different trench widths and jobsite requirements. Contact Iron Lot for available spreader options, pricing, and assistance selecting the appropriate configuration for your excavation.

Applications

The 4′ x 14′ ASF4 provides a longer protected work area than the shorter 4-foot-high ASF4 models. Potential applications include:

• Water and sewer utility work
• Underground pipe installation
• Utility service connections and tie-ins
• Pipe repair and replacement
• Utility exposure and maintenance
• Street and easement excavations
• General underground utility construction

Suitability depends on the excavation and the dimensions of the pipe, structure, utility component, and equipment involved. Contractors should verify required working clearances and the manufacturer’s allowable shield configuration before use.

Steel-Framed Aluminum Construction

The ESC ASF4 series combines aluminum panels with a steel frame, providing an alternative to conventional all-steel trench shields. The 4×14 weighs approximately 4,080 lbs, so contractors should consider the lifting capacity and operating radius of the equipment used to transport, install, reposition, and remove the shield.

Safety and Proper Use

Trench shields must be selected and used in accordance with the manufacturer’s current tabulated data and all applicable OSHA, state, and local excavation-safety requirements. A competent person must evaluate soil conditions, excavation depth, surcharge loads, groundwater, adjacent structures, equipment configuration, and changing jobsite conditions.

The maximum depth ratings shown above should not be used by themselves to determine whether this shield is appropriate for a particular excavation. Refer to the applicable ESC tabulated data for complete requirements, limitations, and allowable configurations.
