Laminated wooden heavy equipment mats (HEMs) are increasingly being used at conventional construction sites such as roads and power lines, and in swampy/marshy areas as logging decks and helicopter pads due to growing stringency and enforcement of environmental regulations. Wood is an ideal material to be used in making HEMs because of its light weight, impact absorption ability and low cost. The substantial increase in demand, especially in western Canada, for wooden HEMs has attracted the attention of wood product producers in Atlantic Canada. Truall Inc., in Grand Falls, New Brunswick, is interested in manufacturing and supplying wooden HEMs to natural resources, energy and construction industries across Canada. These HEMs are made of the wood species native to eastern Canada. This project will investigate the potential use of shorter lumber (less than 20ft) and a few fastening patterns in fabrication of HEMs. The specific objective of this project is to identify fastening patterns and eastern wood species that will have potential in fabrication of HEM in the short term. In the longer term the technical information to be generated in this project will assist in the design of a future research project that will lead to an engineering design approach to wooden HEMs marketed by Truall Inc. To achieve the project objective, the project will be conducted using a combination of experimental and finite element modelling work. 3-ft wide and 20-ft long strip HEM specimens will be fabricated to verify the optimal configuration of HEM identified from finite element analysis. The developed product design, incorporating alternative wood species available in Atlantic Canada, use of lumber with shorter length and strategic fastening patterns will be forwarded to Truall Inc., which would revolutionize the HEM industry. No doubt, the increased demand for HEMs in the resource, construction and energy sectors will generate tremendous business opportunities for Truall across Canada.

层压木质重型设备垫 (HEM) 越来越多地用于传统建筑 道路和电线等地点，以及由于伐木甲板和直升机停机坪等沼泽/沼泽地区 环境法规的日益严格和执行。木材是一种理想的材料 制造 HEM 是因为其重量轻、冲击吸收能力强且成本低。大幅增加 对木制 HEM 的需求，特别是在加拿大西部，引起了木制品的关注 加拿大大西洋地区的生产商。 Truall Inc. 位于新不伦瑞克省 Grand Falls，对制造和 向加拿大各地的自然资源、能源和建筑行业供应木制 HEM。这些 HEM 由原产于加拿大东部的木材品种制成。该项目将调查较短的潜在用途 HEM 制造中的木材（小于 20 英尺）和一些紧固图案。此次活动的具体目标 该项目旨在确定在 HEM 制造中具有潜力的紧固模式和东方木材品种 短期内。从长远来看，该项目产生的技术信息将有助于 设计一个未来的研究项目，该项目将导致市场上销售的木制 HEM 的工程设计方法 由 Truall Inc. 为了实现项目目标，该项目将结合使用 实验和有限元建模工作。 3 英尺宽、20 英尺长的条状 HEM 样本将 制造用于验证通过有限元分析确定的 HEM 的最佳配置。所开发的 产品设计，采用加拿大大西洋地区可用的替代木材品种，使用较短的木材 长度和战略紧固模式将转发给 Truall Inc.，这将彻底改变 HEM 行业。毫无疑问，资源、建筑和能源领域对 HEM 的需求增加将 为 Truall 在加拿大各地创造巨大的商机。
